Sensor Digital de presión para medir la hermeticidad en cañerías de Gas con el celular

En Argentina, cuando el Gasista matriculado realiza una instalación nueva, la debe someter a una prueba de hermeticidad antes de aprobar la obra, para realizar esa prueba el gasista conecta un manómetro, con escala de 1 kg/cm² luego infla la cañería hasta llegar a una presión de 0,2 kg/cm², en una primera etapa las llaves de paso de los artefactos deben estar cerradas, se debe comprobar que la aguja del manómetro quede inmóvil durante 15 minutos, luego se repite la prueba pero con las llaves de paso de los artefactos abiertas, y los robinetes del artefacto cerrados.

La cañería se infla con aire, con un compresor o un inflador de bicicleta.

Un dato importante, la presión nominal del gas natural es de 20 gr/cm² y 28gr/cm² para el gas envasado, y la prueba de hermeticidad se haría a 200 gr/cm² que sería lo mismo que 0,2 kg/cm²

Esta es una foto del d1 mini con el sensor bmp280

//Código para quemar con el arduino ide:

#include <ESP8266WiFi.h>

#include <WiFiClient.h>

#include <Adafruit_BMP280.h>

// Cambia estos valores para conectarte a tu red Wi-Fi

const char* ssid = "cursodegas";

const char* password = "12345678";

// Crea un objeto BMP280

Adafruit_BMP280 bmp;

// Crea un objeto servidor

WiFiServer server(80);

// Variable para almacenar el tiempo de la última actualización

unsigned long lastUpdate = 0;

// Variable para almacenar la presión atmosférica local (en hPa)

float localPressure = 0.0;

void setup() {

// Inicializa el monitor serial

Serial.begin(115200);

// Conéctate a la red Wi-Fi

WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {

delay(1000);

Serial.println("Conectándose a la red Wi-Fi...");

}

Serial.println("Conexión WiFi establecida.");

Serial.println("Dirección IP: ");

Serial.println(WiFi.localIP());

// Inicializa el sensor BMP280

if (!bmp.begin()) {

Serial.println("No se pudo encontrar el sensor BMP280, revisa las conexiones.");

while (1);

}

// Lee la presión atmosférica local para la calibración

localPressure = bmp.readPressure() / 100.0F; // Lectura de presión en hPa

// Inicializa el servidor

server.begin();

Serial.println("Servidor iniciado.");

}

void loop() {

// Declarar variables

float temperature;

float pressure;

// Espera a que se conecte un cliente

WiFiClient client = server.available();

if (!client) {

return;

}

// Lee la petición HTTP

String request = client.readStringUntil('\r');

Serial.println(request);

client.flush();

// Actualiza los valores del sensor si han pasado al menos 2 segundos desde la última actualización

unsigned long now = millis();

if (now - lastUpdate >= 2000) {

temperature = bmp.readTemperature();

pressure = (bmp.readPressure() / 100.0F) - localPressure; // Lectura de presión calibrada en hPa

lastUpdate = now;

}

// Construye la respuesta HTTP

String html = "<html><head><meta http-equiv=\"refresh\" content=\"2\"></head><body>";

html += "<h1>PRESION </h1>";

html += "<p>Temperatura: " + String(temperature) + " &deg;C</p>";

html += "<p>Presion: " + String(pressure,2) + " g/cm2</p>";

html += "</body></html>";

// Envía la respuesta HTTP

client.println("HTTP/1.1 200 OK");

client.println("Content-Type: text/html");

client.println("Connection: close");

client.println("");

client.println(html);

}

// copiar hasta acá

Así se ve en el teléfono, muestra la temperatura tambien

Les cuento que el sensor es muy preciso, si tocan la cañería el calor de sus manos va a aumentar la presión y lo van a poder ver instantáneamente, al igual que si la cañería pierde, esto va a poner a prueba sus instalaciones

Vamos a usar:

sensor de presión barométrica bmp280

un esp8266 d1 mini

una pila 18650

un cargador de batería de litio

opcional, si arman la capsula con termo-fusión, o accesorios de pvc, pero no quieren desarmar para cargar la batería van a necesitar un módulo emisor y receptor cargador de celular inalámbrico

Conexiones: del bmp280 solamente vamos a usar 4 pines

vcc lo conectamos a la salida de 3.3 voltios del d1 mini

gnd a gnd

SCL va al pin D1

SDA va al pin D2

Por ultimo hay que alimentar al d1 mini, primero usaba un módulo dc-dc y lo calibraba a 3.3 voltios, pero en los otros modelos directamente conecté una batería de litio 18650 al pin de 5 voltios del d1 mini

Le pueden colocar un interruptor así queda mas práctico

Funcionamiento del dispositivo, el esp8266 D1 mini se va a conectar por wifi al celular, previamente, hay que configurar el hot-spot del celular, se debe colocar la misma ssid y contraseña del código, entonces una vez que el esp8266 se conectó, nos fijamos que dirección ip le asignó el teléfono, luego pegamos esa dirección ip en el navegador y podremos ver los valores del sensor de presión en el teléfono, la pagina se va a actualizar cada 2 segundos

Un dato importante es que el sensor bmp 280 entrega el resultado de la presión en pascales, en el código se cambia ese valor a hecto pascales y para que tengan una idea 200 hectopascales es igual a 0,204 kg/m² que serían 204 gr/cm².

Recuerde que si requiere una precisión mas exacta, por mas que la pagina diga el valor en gramos sobre centímetro cuadrado, en realidad son hecto pascales, puede usar una página web que haga la conversión, como no es una diferencia significativa para mi lo deje así.

Entonces si leemos 200 g/cm² en realidad son 204 gr/cm²

o si tenemos una lectura de 28 hectopascales en realidad es 28,55 gramos/cm²

para mi es lo mismo, no es un error muy grande, probé con otras ecuaciones en la parte que hace la conversión y divide por 100F pero me daba errores de medición

Para que sea mas fácil tomar la lectura de la presión, lo primero que hace el código es tomar una lectura y luego restarla a las siguientes lecturas, de ese modo se calibra el sensor a cero, para que entiendan, por ejemplo, antes de hacer esa modificación, el sensor media mas o menos desde los 946 hecto pascales, que es la altura a nivel del mar a donde estoy, entonces tenía que inflar la cañería a 1146 hecto pascales, obviamente el valor de cero se va a ir corriendo a medida que pasa el tiempo, entonces si dejan pasar mucho tiempo entre lectura y lectura van a tener que resetear el d1 mini, habría que ver si se puede colocar un botón de reset en la página así no hay que desarmar el instrumento

Acá se ven las cápsulas de pvc

La librería del bmp280 la pueden descargar de:

Deben recordar cambiar un valo, sino da error, tienen que entrar al directorio donde esta instalado el arduino ide, luego van a librerías, entran a (Adafruit_BMP280_Library), y al archivo (Adafruit_BMP280.h) lo tienen que abrir como archivo de texto y en la linea 37 cambian (0x77) por (0x76) guardan y cierran, y reinicien el arduino ide

La cápsula que vincula el aparato este a la cañería debe ser de pvc, probé con cañería epoxi pero cuando cerraba la tapa se cortaba la conexión wifi entre el d1 mini y el teléfono

habría que probar de colocar un módulo emisor y receptor cargador de celular inalámbrico y el módulo de carga para baterías de litio, el que trae protección y hacer la capsula totalmente sellada, con termo-fusión

Al principio usaba un arduino nano y el sensor bmp 280. Sacaba 4 cables desde dentro de la cañería para visualizar los datos en una pantalla oled, pero por mas sellador que colocaba, siempre, el aire se escapaba por los cables, así que opté por usar el esp8266 d1 mini que es uno de los módulos mas chicos, e introducir el sensor dentro de la cañería.

El código lo pueden quemar con el ide de arduino, antes tienen que instalar las librerías del esp8266, en este tutorial explican como es el procedimiento:

En esta parte del código pueden cambiar las credenciales del wifi que liberan desde el teléfono, obviamente tienen que coincidir así el d1 mini se conecta al wifi que libera el teléfono

const char* ssid = "cursodegas";

const char* password = "12345678";

Bueno eso es todo por ahora, esto es un prototipo, y lo comparto por si quieren probarlo o hacerle alguna modificación, muchas gracias a la gente del CEDER de Villa Carlos Paz, a mi primer profesor, que le gustaban mis proyectos y me alentaba a seguir adelante, se llama Roberto Muñoz y también al profesor actual, Andrés Bustos, me brindaron muchos consejos

Si alguien quiere que le venda un prototipo listo, la parte electrónica, la envío por correo, puede contactarme al 351-3854282

AZ-Envy - Sensordaten auf einer Webseite

In diesem Beitrag möchte ich dir zeigen, wie du die Sensordaten vom AZ-Envy auf einer Webseite anzeigen lässt.

Den AZ-Envy habe ich dir bereits in den beiden nachfolgend verlinkten Beiträgen vorgestellt und gezeigt wie dieser programmiert wird. - Vorstellung AZ-Envy - AZ-Envy - auslesen der Sensordaten Hier soll es lediglich darum gehen, wie du eine HTML-Seite mit einem Liniendiagramm schreibst und dort die Sensordaten für die Luftqualität, Temperatur sowie rel. Luftfeuchtigkeit darstellst.

AZ-Envy im Überblick

Der AZ-Envy verfügt wie erwähnt über einen Luftqualitätsmesser vom Typ MQ-2 sowie ein Luftfeuchtigkeits-/Temperaturmesser SHT30.

Aufbau des Boards "AZ-Envy"

Aufbau einer Wi-Fi-Verbindung

Auf meinem Blog habe ich dir bereits einige Beiträge veröffentlicht, wo ich dir gezeigt habe, wie du eine Wi-Fi-Verbindung am Mikrocontroller mit ESP Chip aufbaust. Du benötigst von deinem lokalen WLAN die SSID sowie das Passwort. Der ESP8266 arbeitet im 2.4 GHz WLAN daher musst du hier ggf. im Router darauf achten welches Netzwerk bei dir aktiv ist! //Bibliothek zum Aufbau einer WiFi Verbindung #include //SSID aus dem Router const char* ssid = ""; //Passwort für den Zugang zum WLAN const char* password = ""; //Aufbau eines Webservers mit HttpPort 80 WiFiServer server(80); void setupWiFi() { //Ausgabe der SSID auf der seriellen Schnittstelle Serial.print("Aufbau der WiFi Verbindung zu "); Serial.print(ssid); Serial.print(" "); WiFi.begin(ssid, password); int index = 0; //Warten bis die Verbindung aufgebaut wurde, //oder 10 Versuche gescheitert sind. while (WiFi.status() != WL_CONNECTED || index < 11) { delay(500); index++; //incrementieren des Indexes Serial.print("."); } Serial.println(); //Wenn die Verbindung erfolgreich aufgebaut wurde, //dann soll die IP-Adresse ausgegeben werden. if (WiFi.status() == WL_CONNECTED) { Serial.print("IP-Adresse: "); Serial.println(WiFi.localIP().toString()); } } void setup() { //begin der seriellen Kommunikation Serial.begin(9600); //Aufrufen der Funktion setupWiFi //zum Aufbau der WiFi-Verbindung. setupWiFi(); } void loop() { // bleibt erstmal leer } Wenn das Programm erfolgreich auf den Mikrocontroller gespeichert / hochgeladen wurde, dann sollten wir nachfolgende Ausgabe im seriellen Monitor der Arduino IDE sehen.

Die IP-Adresse können wir nun im Browser eingeben, jedoch werden wir zunächst nur eine Fehlermeldung.

Damit du den Code nicht abtippen musst, kann du dir diesen hier bequem als ZIP-Datei herunterladen.

Erstellen einer Webseite für die Sensordaten

Zunächst schreiben wir die Webseite in einem einfachen Editor wie dem Notepad++. Da wir diese Webseite später vom Mikrocontroller ausliefern möchten, müssen wir diese komprimiert in einer Variablen im Quellcode ablegen (aber dazu später mehr). Im ersten Schritt möchten wir lediglich die Daten anzeigen lassen. Die Uhrzeit & das Datum ermitteln wir per JavaScript und sparen uns somit einen Zugriff auf NTP-Server, wie ich es im Beitrag ESP8266 – NTP Protokoll für das lesen eines genauen Zeitstempels erläutert habe.

Der Code für dieses kleine Projekt ist schon jetzt recht umfangreich, daher biete ich dir hier einfach die ZIP-Datei zum Download mit allen Ressourcen an. Die Bibliothek jQuery sowie die CSS-Stylesheets und JavaScript Dateien habe ich auf meiner Domain unter http://progs.ressourcen-draeger-it.de/azenvy/ abgelegt, somit kannst du dir diese recht einfach einbinden.

14 Awesome Arduino Cloud Features You Never Knew Existed

Tweet

There are dozens, if not hundreds of amazing Arduino Cloud features. So it’s perfectly understandable if you’ve missed some of them.

So we’ve put together a list of our favorite Arduino Cloud features that you might not know existed.

1) Auto-generate Sketches

We’ve talked elsewhere about getting an understanding of what cloud computing really is, and how it’s not just the domain of experts. The cloud is how total beginners can get started much more easily. There’s no better demonstration of that than our first top Arduino Cloud feature; auto-generated sketches.

When you create a new “Thing” in your Arduino Cloud, you add various bits of info to it. Wi-Fi connection credentials, and any variables you want to control or monitor. The Cloud automatically generates a starting sketch from this info. That sketch can then be sent to your boards, so all your initial configuration is taken care of, without a single line of code.

2) Device-to-Device Communication

There’s simply no easier way to make two microcontroller boards talk to each other than Arduino Cloud. We’ve covered in detail how easy it is to wirelessly connect your boards.

This isn’t just for Arduino devices either. If you want any combination of Arduino, ESP32 and ESP8266 devices to work together, this is how you do it.

3) Over-the-Air Updates

Working through your Arduino Cloud means you don’t have to disconnect any Arduino boards when updating them. If you want to edit or add a new sketch, it can all be done wirelessly, over-the-air.

Anyone who’s had to dismantle a project or device to get to a board’s USB socket will appreciate the simple, vital value of this feature. It’s one of those things that you’ll wonder how you ever lived without.

4) Support for ESP Boards

There’s a reason we call it the Arduino IoT Cloud. This is an all-encompassing platform for Internet of things, home automation, and electronics project control and management. So first we added support for ESP8266 devices. More recently, experimental support for ESP32 boards became available.

So even if your project doesn’t actually have any Arduino products in there, the Cloud is just as useful. Secure, private, and accessible to all kinds of IoT and maker devices.

5) Trigger Actions on Cloud Events

Arduino Cloud makes it super easy to do things that you might normally need the IDE for. But it’s also got lots of exclusive features that you only get in the Cloud.

For example, there are actions that can be triggered based on your board’s interactions with your Arduino Cloud. You can include actions within your sketches when a Cloud connection is successful, and when the Cloud has synced with a device. Or perhaps most useful of all, trigger an action if Cloud connectivity is lost. Getting an indication that a project has disconnected could be incredibly useful!

Here’s an example of using these actions within a sketch.

6) Sharing Your Dashboards

Dashboards are control panels within your Arduino Cloud. It’s one of the most powerful Arduino Cloud features, and essential to making full use of Cloud control. But what’s often overlooked is that you can share dashboards with anyone you want.

For example, let’s say you’re using Arduino Cloud to control your home automation. You can set up a dashboard for a tablet in the living room that the whole family can use, but doesn’t have sensitive admin controls in there. And then another for people to use on their phones. 

All Cloud plans include unlimited dashboards. And anyone can have a free Cloud account. So you can create as many dashboards as you like, and share them with literally anyone, anywhere.

7) Alexa Integration

Natural language voice control is genuine Star Trek stuff. So it’s no wonder people love the functionality of Alexa. Did you know it’s incredibly easy to connect your Arduino Cloud to Alexa? And once you have, it effectively adds voice control to every board, and every project. Nothing else needed.

There’s literally no easier way to make an Alexa-controlled device or project than with your Arduino Cloud. You’ll never look back, and you’ll always have someone to talk to.

8) Full API Integration

For the engineers, coders, developers and those among you who’ve been using Arduino for a long time, API integration is the powerhouse secret feature you’ve been looking for.

The API can be called with any HTTP client, or with languages like Javascript, Python, Golang and more. It’s what you need to incorporate the power of Arduino Cloud features into your systems, platforms and projects.

9) Use IFTT, Zapier and More with Webhooks

There are lots of reasons you might want to include control platforms outside of your Arduino Cloud. Like sending an email or a Tweet when you press a button on a Nano, or a device disconnects from the Cloud (see above).

That’s what webhooks are for, and they give you a universal way to send commands out of Arduino Cloud, and into… well, anything!

IFTTT and Zapier are great examples of services that can do almost anything from a webhook. Get to know this feature, and connected projects suddenly have easy access to the whole web.

10) Easy Firmware Updates

When you connect a new Arduino board, your Arduino Cloud automatically checks its firmware version. If there’s an update available, it offers you the option of applying that update.

Very easy, and you don’t have to worry about finding the correct/latest firmware version yourself. This simple, background function makes sure your boards and projects always have the latest features, security updates and bug fixes.

For people who use a lot of Arduino devices, it’s worth adding them to the Cloud for this feature alone.

11) Full Dashboard Customization

We’ve already talked about unlimited dashboards in your Arduino Cloud. Creating them is easy, but did you know you can customize them too?

Anyone who’s dipped their toe in the home automation waters knows how essential dashboard editing is. Some platforms work great, but offer very little when it comes to controlling your dashboard layout. For many people, that’s a deal breaker.

Your Arduino Cloud widgets can easily be added, edited, removed, repositioned and resized in any configuration you want. It’s as simple as drawing and resizing boxes, but the result makes your Cloud projects infinitely more useable.

12) Watchdog Timer

The Arduino Cloud automatically runs a watchdog timer that will reset your board, hardware or project if it crashes. This is a small feature, but a powerful one that can keep your projects running while unattended. 

It means you never have to manually reset it when you eventually realize it’s not been running all day. You can have devices running remotely (very remotely, with SIM or LoRa connectivity) and be sure they’re robust enough to keep on ticking.

It’s included and running automatically, but can easily be disabled if you don’t need it.

13) Node-RED Integration

Arduino provides a super easy way to use Node-RED for IoT automations. This is a powerful, but very easy-to-use visual programming platform specifically designed for IoT projects.

Complex automations using advanced triggers like sunrise or sunset, presence detection, combined actions or sensor readings and so much more. The possibilities are endless, and learning Node-Red is incredibly easy. Get to grips with this feature, and you’ll be creating IoT automations that would otherwise need an experienced coder.

13A) Fully Functional Free Account

One of the best kept secrets of the Arduino Cloud is that if you’re registered on the Arduino website or forum, you already have a free Cloud waiting for you. Simply head on over to the Cloud site and get started with unlimited dashboards and unlimited sketches. The free tier of Arduino Cloud is fully functional, and it’s ready and waiting for you to give it a try.

In fact, it’s the perfect option especially if you haven’t used Arduino before! Give it a shot and let us know what you think. No credit card required; just your creativity and a passion for connected projects.

Swordsoft layout serial number

SWORDSOFT LAYOUT SERIAL NUMBER HOW TO

SWORDSOFT LAYOUT SERIAL NUMBER CODE

However, if you have peripherals connected to those pins, you may have trouble trying to upload new code, flashing the ESP32 with new firmware, or resetting the board. More information on the ESP32 Boot Mode Selection can be found here. The board puts the pins in the right state for flashing or boot mode. On most development boards with built-in USB/Serial, you don’t need to worry about the state of these pins. These are used to put the ESP32 into bootloader or flashing mode. The ESP32 chip has the following strapping pins:

SWORDSOFT LAYOUT SERIAL NUMBER HOW TO

Learn how to use interrupts with the ESP32: Learn more about SPI communication protocol with the ESP32 using Arduino IDE: ESP32 SPI Communication: Set Pins, Multiple SPI Bus Interfaces, and Peripherals (Arduino IDE) InterruptsĪll GPIOs can be configured as interrupts. Learn more about I2C communication protocol with the ESP32 using Arduino IDE: ESP32 I2C Communication (Set Pins, Multiple Bus Interfaces and Peripherals) SPIīy default, the pin mapping for SPI is: SPI If you want to use other pins when using the wire library, you just need to call: Wire.begin(SDA, SCL) When using the ESP32 with the Arduino IDE, the default I2C pins are: The ESP32 has two I2C channels and any pin can be set as SDA or SCL. Learn how to use ESP32 PWM with Arduino IDE: ESP32 PWM with Arduino IDE I2C GPIO where you want to output the signal.To set a PWM signal, you need to define these parameters in the code: All pins that can act as outputs can be used as PWM pins (GPIOs 34 to 39 can’t generate PWM). The ESP32 LED PWM controller has 16 independent channels that can be configured to generate PWM signals with different properties. Learn how to use the RTC GPIOs to wake up the ESP32 from deep sleep: ESP32 Deep Sleep with Arduino IDE and Wake Up Sources PWM The following GPIOs can be used as an external wake up source. These RTC GPIOs can be used to wake up the ESP32 from deep sleep when the Ultra Low Power (ULP) co-processor is running. The GPIOs routed to the RTC low-power subsystem can be used when the ESP32 is in deep sleep. There are 2 x 8 bits DAC channels on the ESP32 to convert digital signals into analog voltage signal outputs. View source Digital to Analog Converter (DAC) You’ll get a behavior similar to the one shown in the following figure. You need to keep that in mind when using the ADC pins. You’ll probably won’t be able to distinguish between 0 and 0.1V, or between 3.2 and 3.3V. The ESP32 ADC pins don’t have a linear behavior.

SWORDSOFT LAYOUT SERIAL NUMBER CODE

You can also set the resolution of your channels on the code and the ADC range. This means that you can get analog readings ranging from 0 to 4095, in which 0 corresponds to 0V and 4095 to 3.3V. The ADC input channels have a 12-bit resolution. So, if you’re using Wi-Fi and you’re having trouble getting the value from an ADC2 GPIO, you may consider using an ADC1 GPIO instead. Note: ADC2 pins cannot be used when Wi-Fi is used. The ESP32 has 18 x 12 bits ADC input channels (while the ESP8266 only has 1x 10 bits ADC). These are the GPIOs that can be used as ADC and respective channels: Learn how to use the touch pins with Arduino IDE: ESP32 Touch Pins with Arduino IDE Analog to Digital Converter (ADC) Those internal touch sensors are connected to these GPIOs: The capacitive touch pins can also be used to wake up the ESP32 from deep sleep. These pins can be easily integrated into capacitive pads and replace mechanical buttons. So they can detect variations induced when touching the GPIOs with a finger. These can sense variations in anything that holds an electrical charge, like the human skin. The ESP32 has 10 internal capacitive touch sensors. So, don’t use these pins in your projects: However, these pins are connected to the integrated SPI flash on the ESP-WROOM-32 chip and are not recommended for other uses. GPIO 6 to GPIO 11 are exposed in some ESP32 development boards. They can’t be used as outputs, so use these pins only as inputs: These pins don’t have internal pull-up or pull-down resistors. GPIOs 34 to 39 are GPIs – input only pins. GPIOĬontinue reading for a more detail and in-depth analysis of the ESP32 GPIOs and its functions. The pins highlighted in red are not recommended to use as inputs or outputs. The ones highlighted in yellow are OK to use, but you need to pay attention because they may have an unexpected behavior mainly at boot. The pins highlighted in green are OK to use. The following table shows what pins are best to use as inputs, outputs and which ones you need to be cautious. Additionally, there are pins with specific features that make them suitable or not for a particular project.

Arduino Tutorial 61: NodeMCU ESP8266 mit OLED Display

In diesem Tutorial möchte ich einen Mikrocontroller mit einem verbauten OLED Display vorstellen. Der Mikrocontroller ist ein NodeMCU mit einem ESP8266 Wi-Fi Chip.

NodeMCU mit OLED Display Einen NodeMCU habe ich bereits im Tutorial NodeMCU – “Einer für (fast) Alles!” vorgestellt und möchte hier nun auf den betrieb mit dem OLED Display eingehen. Der Microcontroller wurde mir vom Onlineshop Makershop.de für ein Review zur Verfügung gestellt. 

Bezug

Den Mikrocontroller kannst du auf ebay.de im Shop von Makershop.de für 14,45 € erwerben (Versandkosten fallen nicht an).

Technische Daten des NodeMCU mit OLED Display

NodeMCU - 12 digitale Pins - 1 analoger Eingang - Micro-USB Buchse - Eingangsspannung 4,75V bis 12V - Abmaße 6,2 cm x 2,7 cm OLED Display - Abmaße 0,96 Zoll (2,7 cm x 1,5 cm)

Besonderheiten

Der NodeMCU mit OLED Display ist breiter als der NodeMCU.

Vergleich von einfachen NodeMCU mit einem mit Display Wenn der Mikrocontroller auf ein Steckbrett verbaut wird, so kann man nur eine Pinreihe verwenden.

NodeMCU auf einem Steckbrett verbaut Auf dem NodeMCU mit OLED Display ist bereits ein Sketch installiert, welcher auf dem Display einige Funktionen zeigt.

  Quellcode

In den nachfolgenden Beispielen möchte ich aufzeigen wie das Display des Mikrocontrollers betrieben wird. Installation der benötigten Bibliothek Für den Betrieb des Displays wird eine Bibliothek benötigt, diese kann man bequem über die Arduino IDE installieren. Dazu wird über das Hauptmenü der Eintrag "Sketch" (1) -> "Bibliothek einbinden" (2) -> "Bibliotheken verwalten ..." (3) navigiert. 

Öffnen des Boardverwalters Es sollte sich nun nach einer kurzen Ladezeit der Boardverwalter öffnen. In diesem Dialog suchen wir zunächst nach dem Eintrag "SSD1306" (1) danach wird der Eintrag "ESP8266 and ESP32 Oled Driver for SSD1306 ...."(2) ausgewählt. Nun noch die Schaltfläche "Installieren" (3) betätigen. Nachdem die Installation erfolgreich war, kann der Dialog mit der Schaltfläche "Schließen" (4) geschlossen werden.

Boardverwalter, installieren der SSD1306 Bibliothek für das OLED Display Wie üblich bringt auch diese Bibliothek einige Beispiele mit, welche nach einer kleinen Konfiguration lauffähig sind.

ESP OLED Display Bibliothek - Beispiele SDA & SCL Das Display ist über die digitalen Pins D1 - SDA & D2 - SCL angeschlossen, dieses muss in den Beispielen geändert / angepasst werden. Dann sind diese jedoch lauffähig. Hello World! Als Erstes ein Klassiker "Hello World!". Für die Darstellung von Text kann man zwischen 3 Schriftgrößen wählen.

Schriftgrössen auf dem OLED Display Für unser "Hello World!" reicht die Schriftgröße 16 völlig aus. #include //Bibliothek für die Arduino IDE setTextAlignment(TEXT_ALIGN_LEFT); display->setFont(ArialMT_Plain_16); display->drawString(0, 0, "Hello World!"); } //Array mit den Frames für das Display. //Jeder Eintrag in diesem Array repräsentiert eine Darstellung //des Displays. FrameCallback frames = { helloFrame}; //Anzahl der maximalen Frames welche angezeigt werden sollen. const int frameCount = 1; void setup() { //Setzen der Bildwiederholungsfrequenz ui.setTargetFPS(60); //Setzen der Frames sowie die Anzahl der Frames. ui.setFrames(frames, frameCount); //Initialisieren der Oberfläche. ui.init(); //Bildschirm drehen, ansonsten ist die Darstellung auf dem Kopf. display.flipScreenVertically(); } void loop() { int remainingTimeBudget = ui.update(); } Textausgabe auf dem OLED Display

Ausgabe des Textes "Hello World!" auf dem OLED Display Einfache Grafiken Auf dem OLED Display können einfache Grafiken angezeigt werden. In dem Sketch, welcher ab Werk auf dem NodeMCU installiert wurde ist  das Wifi Zeichen zu sehen. Wollen wir uns also nun mal ansehen wie eine Grafik auf dem Display erzeugt werden kann. X BitMap Image Die Bilder, welche auf dem Display angezeigt werden können, müssen im X Bitmap Format vorliegen. Auf Wikipedia ist ein kleiner Beitrag zum X Bitmap Format zu finden: X BitMap (XBM) ist ein Format für die Darstellung von monochromen Rastergrafiken, hauptsächlich Cursors und Icons. Das XBM-Dateiformat wurde 1989 durch XPM für X11 ersetzt. Die Grafiken bestehen aus reinen Textdateien; sie können mit einem einfachen Texteditor bearbeitet und direkt in C-Quellcode eingebunden werden. Seite „X BitMap“. In: Wikipedia, Die freie Enzyklopädie. Bearbeitungsstand: 21. November 2017, 09:08 UTC. URL: https://de.wikipedia.org/w/index.php?title=X_BitMap&oldid=171218654 (Abgerufen: 17. August 2018, 10:06 UTC) Umandeln von PNG nach XBM Um ein Bild in das XBM Format umzuwandeln, muss man nicht unbedingt spezielle Software erwerben, man kann dieses bequem online mit dem Tool https://www.online-utility.org/image/convert/to/XBM erledigt. Hier lädt man das gewünschte Bild hoch und kann die XBM Datei herunterladen.

Online PNG to XBM Converter Ich habe mein Logo im Format 48x48 Pixel hochgeladen und eine Datei mit folgendem Inhalt heruntergeladen: #define 1534500608686_width 48 #define 1534500608686_height 48 static char 1534500608686_bits = { 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xF7, 0xBE, 0xEF, 0xFB, 0xFE, 0x07, 0x00, 0x00, 0x00, 0x00, 0xE0, 0x07, 0x00, 0x00, 0x00, 0x00, 0xC0, 0x03, 0x03, 0x00, 0x00, 0x00, 0xC0, 0xA3, 0x3B, 0x8D, 0xA3, 0x69, 0x8E, 0x21, 0x19, 0xCE, 0xB6, 0x6D, 0xC3, 0x73, 0x8B, 0xD9, 0x90, 0x1D, 0xC2, 0x63, 0x1B, 0xCB, 0xB5, 0x1D, 0xC2, 0x03, 0x00, 0x20, 0x80, 0x01, 0xC0, 0x03, 0x00, 0x78, 0xF4, 0x01, 0xC0, 0x03, 0x00, 0x3C, 0x01, 0x02, 0x80, 0x01, 0x00, 0x9E, 0xC2, 0x01, 0xC0, 0x03, 0x00, 0x67, 0xF5, 0x01, 0xC0, 0x03, 0x80, 0x97, 0xFE, 0x03, 0x40, 0x03, 0xC0, 0x6D, 0x7D, 0x06, 0xC0, 0x03, 0xF0, 0xD6, 0xFD, 0x0E, 0xC0, 0x03, 0xF0, 0x5F, 0xBE, 0x39, 0xC0, 0x01, 0xFC, 0x7F, 0xFF, 0x36, 0xC0, 0x03, 0xEC, 0xBF, 0x5F, 0x63, 0xC0, 0x03, 0xFE, 0xDF, 0x7F, 0xDB, 0xC0, 0x03, 0xFF, 0xFF, 0xEF, 0xBD, 0x81, 0x03, 0xFF, 0xEF, 0xDF, 0x9B, 0xC1, 0x83, 0xFF, 0x7F, 0xF7, 0xFF, 0xC3, 0x01, 0xFF, 0xEF, 0xFF, 0xFF, 0xC3, 0x03, 0xFF, 0xFF, 0xFF, 0xFF, 0xC1, 0x03, 0xFF, 0x77, 0xFF, 0xFF, 0xC1, 0x03, 0xFE, 0xF7, 0xFF, 0xFF, 0x80, 0x03, 0xF8, 0xFF, 0xFF, 0x7F, 0xC0, 0x03, 0xF8, 0xFF, 0xFF, 0x3F, 0xC0, 0x01, 0xF0, 0xFE, 0xFF, 0x1F, 0xC0, 0x03, 0xF0, 0xFE, 0xFF, 0x0F, 0xC0, 0x03, 0x00, 0xFF, 0xFF, 0x0F, 0xC0, 0x03, 0x80, 0xFB, 0xFF, 0x03, 0xC0, 0x03, 0xC0, 0xFD, 0xFF, 0x01, 0x40, 0x03, 0xC0, 0xFD, 0xFF, 0x00, 0xC0, 0x01, 0x40, 0xF8, 0x77, 0x00, 0xC0, 0x63, 0x00, 0xFC, 0x2F, 0x00, 0xC0, 0x43, 0x06, 0x1C, 0x0D, 0x00, 0x40, 0x63, 0x06, 0xDC, 0xCD, 0x6E, 0xC6, 0x63, 0xC6, 0xCD, 0x4C, 0x6C, 0xC6, 0x63, 0x06, 0xCC, 0xEC, 0x6E, 0xCE, 0x21, 0x04, 0x24, 0x88, 0xC2, 0x4E, 0x03, 0x00, 0x00, 0x00, 0x00, 0xC6, 0x03, 0x00, 0x00, 0x00, 0x00, 0xC0, 0x07, 0x00, 0x00, 0x00, 0x00, 0xE0, 0x7F, 0xDF, 0xF7, 0xFD, 0xFD, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xBF, 0xFF, }; Quellcode Ich musste den Datentyp für das Bild von "static char " in "const uint8_t" ändern. Ansonsten habe ich mich am Beispiel orientiert. #include //Bibliothek für die Arduino IDE drawXbm(x + 34, y + 14, img_Width, img_Height, image); } //Array mit den Frames für das Display. //Jeder Eintrag in diesem Array repräsentiert eine Darstellung //des Displays. FrameCallback frames = { imageFrame}; //Anzahl der maximalen Frames welche angezeigt werden sollen. //Wenn der Wert 0 ist dann wird nur das erste Frame angezeigt und //die Seitenanzeige im Display entfällt. const int frameCount = 0; void setup() { //Setzen der Bildwiederholungsfrequenz ui.setTargetFPS(60); //Setzen der Frames sowie die Anzahl der Frames. ui.setFrames(frames, frameCount); //Initialisieren der Oberfläche. ui.init(); //Bildschirm drehen, ansonsten ist die Darstellung auf dem Kopf. display.flipScreenVertically(); } void loop() { int remainingTimeBudget = ui.update(); } Ausgabe des Bildes auf dem OLED Display Das Logo wird relativ gut dargestellt, jedoch wird deutlich das bei einem weniger aufwändigen Bild das Display seine stärken zeigen kann.
