attack on titan characters playing league headcanons

guys im in my final year of my undergrad and i have exams and this is what im doing w my time LMAO

eren (ultimate rage quitter)

eren is the ultimate tryhard. bro mains riven and screams into the group call "i will carry!" he charges into fights like he’s fighting titans, only to get instantly melted. after dying for the fifth time, you can hear him scream into the mike, “i’m not mad, i’m just... passionate! WE GOT THIS GUYS DONT GIVE UP” while furiously typing “ff 15” in chat.

mikasa the overprotective bodyguard

mikasa is the ultimate support, but she’s less about healing and more about throwing daggers at anyone who dares touch eren. if someone tries to gank him, she’ll sprint across the map like a ninja, yelling, “no one touches my eren!” while simultaneously saving him from certain doom… and then getting herself killed in the process.

armin the strategist (and coward)

armin is the brains of the operation, but he spends half the game hiding in a bush, whispering strategies to himself. when he finally decides to engage, he shouts, “guys! let’s flank them!” only for everyone to be dead by the time he finishes his sentence. he’s basically a walking “how not to play” guide.

sasha the snack master

sasha is the adc, but her real focus is on her snack stash. she’s munching on chips while trying to farm minions and will often say things like, “just one more potato chip before i go back!” she ends up feeding because she can’t resist grabbing a snack during team fights. “i’m just… multitasking!”

connie the confused support

connie thinks he’s playing support, but he keeps accidentally stealing kills with his abilities. when everyone yells at him, he responds with a confused, “but i thought we were playing catch!” he’s just trying to help, bless his little heart.

jean's leadership failures

jean wants to be team captain (literally no one cares) and constantly tries to direct everyone like he’s leading a military operation. “okay, guys! we need a five-man engage!” but when eren charges in solo again, jean just facepalms and mutters, “why do i even try?”

marco the cheerleader

marco is the wholesome cheerleader of the group. he’s always encouraging everyone with phrases like, “good job, team! you can do it!” unfortunately, he gets so distracted by his own positivity that he forgets to ward properly and walks straight into a bush full of enemies. “oops! my bad!”

reiner's tanking fail

reiner plays tank but thinks he’s invincible. he charges into fights yelling, “i’m here to save you!” only to get one-shot by an enemy assassin. his teammates are left screaming, “we needed you alive for that!”

ymir's sneaky shenanigans

ymir plays an assassin and loves sneaking around for picks. she’ll shout things like, “i’m going in!” but then accidentally reveals her position by stepping on a ward. when historia asks her what happened, she just shrugs and says, “it was tactical misdirection!”

annie’s solo queue dominance

annie is a solo queue legend who plays mid-lane like it’s her personal arena. she rolls her eyes at her teammates’ antics and mutters things like, “if you all just let me carry…” she has zero patience for anyone who doesn’t understand how to play properly—and she’ll mute them faster than you can say “teamwork.”

bertolt's unexpected support skills

birthcontrol is surprisingly good at support, using his size as an accidental shield for his teammates. when someone asks how he does it, he just says softly, “i’m just… really good at standing still.” and somehow that works....

erwin's confusing speeches

erwin gives motivational speeches before every match that leave everyone more confused than inspired. “remember: victory is not just about winning; it’s about… uh… being brave?” anywyas by the end of it, everyone is just staring blankly at him while eren types in chat: “can we just play already?”

hange's chaotic jungle adventures

hange plays jungle with chaotic energy that keeps everyone on their toes. they dive into fights yelling, “let’s go! science rules!” but often end up accidentally initiating fights they can’t win. then they die spectacularly the end

levi's silent judgment

levi lurks in the background, silently judging everyone while occasionally throwing out sarcastic comments like, “great job feeding.” when asked why he doesn’t play more often, he simply replies with a deadpan stare: "because i don’t want to ruin my kda." and yet somehow still manages to carry every game when he does play

PCM1840 Quad Input Microphone I2S ADC with Hardware Pin Configuration 🔊🎤🛠️

We looked up this chip in 2021, right before we got smacked with a chip shortage and couldn't get any to prototype with - but we're back in biz and respinning a prototype up. While looking up the TLV320ADC quad microphone I2S ADC, we also bumped into the PCM1840. These chips are similar (almost identical pinout) but have analog-only inputs and no I2C or SPI configuration. Yep, it's completely hardware pin bootstrapped, which makes setup much easier because you can use any I2S driver. It can act as an I2S controller (it clocks all I2S pins out) or the I2S peripheral (I2S clocks input and data is output). We whipped together a breakout to figure out how to get TDM I2S input working without dealing with the I2C setup. Looks awesome for spatial audio algorithms and voice recognition projects. You can pick up the PCM1840 ADC on DigiKey - lots are in stock!

dream log 194

apparently it was an adrians digital basment / amazing digital circus crossover. that's weird lol i feel weird writing a story about a real person.

(in case people dont know, adrians digital basement is a guy on youtube who repairs vintage computers)

so he got in a new computer. pretty generic looking beige late 90s pc. seemed very normal except for a big connector on an expansion card in the back labeled "helmet"

he opened the computer up, again pretty standard stuff for the era. the only other unusual thing was the ethernet card, adrian theorized it may have been a business machine. he pulled out the weird expansion card and it said "adc v2.0" and had two large chips labeled "caine" and "bubble" with cryptic part numbers, along with a variety of normal components. a quick google search didn't turn up anything relevant.

the hard drive was in the computer so he decided to turn it on. some text flashed across the screen, clearly not windows or dos. it didn't resemble linux either. a custom os? then an intro played. "the amazing digital circus, hmm must be some kind of video game" adrian remarked. on screen, caine said "hello new user! welcome to the amazing digital circus. you cant do much without putting on your helmet but if you want to learn more click on the things! also you need a network connection if you want to play with others, or else it's just gonna be you and me in here." so adrian clicked around and caine blathered on, but in the end the system was incomplete without the helmet. "must be some kind of early vr thing. that's interesting. maybe i could reverse engineer the interface". when adrian hit the power button to turn off the computer, caine said "nope cant do that" the only way he could turn off the machine was to unplug it. signing of at the end of his video, adrian asked us the viewers if we knew anything else about this computer or the game that was installed on it, and remember to like and subscribe. the end.

[synths-and-sensibility]

Good news! I figured out my quantization algorithm! I still need to translate it from Python to C and get it on an Arduino, but I've pretty much got the core of it figured out. General concept is when the note selection is changed, a new array of allowed notes (in the form of DAC values) is generated. Then when the input analog signal is read, it will do a binary search to determine the next lowest allowed note*. It's probably not optimized at all, but if it runs fast enough, I don't know that it really matters.

(*crap, I forgot to test it with the root note unselected... but it wouldn't be too hard to throw a check in there if the input is below the lowest allowed value)

I still got a lot of functionality to flesh out for the sequencer, but I'm excited the quantization seems to have a solution. I guess the next step is to get an external ADC chip running since I actually do have an MCP3008 and a bunch of pots lying around.

i probably could make a long (11s @ 8 bit, 22KHz, but clock varies from 5k to 100k) digital signal delay line without using a microcontroller at all.. i could just smoosh the ADC, DAC and memory on a data bus and just sequence their enable/disable pins etc to make things tick. I probably will try doing that this year. Probably slap some fun antialiasing out there too while i'm at it..

"But Auby you could take teensy ARM microcomputer raspberry micro and have minutes of 16-bit delay" do i look like a coward. the reason is not just function but also making funny chips do as i say with proper connections.

What is BSP? Top 8 Advantages of BSP Development.

“BSP”(Board Support Package Development) term was first used in the year 1981 when the developers of the VRTX, Hunter & Ready described the hardware-dependent software which is needed to run on a specific hardware platform.

A BSP is a necessary code provided for a computer hardware device that enables that specific device to function with the computer's operating system. The Board Support Package includes a small program popularly called a boot manager or bootloader that places the device drivers and the operating system into memory.

A board-specific or board family-specific Board Support Package is created. It is a library that provides application layer control over low-level hardware drivers via APIs. The major APIs provided will be to Configure, Initialize, Enable and Disable the peripheral.

It aids in the development of any applications for the Real-Time Operating System and the customer hardware. To put it simply, BSP offers an interface that allows Real-Time Operating Systems to be supported with both standard and custom embedded hardware designs. Software templates, such as skeleton device driver code and code for lower-level system functions needed by some of the specific hardware devices, are made possible with the assistance of BSP. Complete understanding of the low-level architecture of the Board and Hardware Software Interface is required to perform BSP development.

Advantages of Board Support Package Development.

Standard peripherals include Clock, SPI,12C, ADC, DAC, BLE, UART. BSP targets the APIs for hardware peripherals specifically, which is the primary distinction between it and SDK.  On the Contrary, SDK is not tied to the underlying hardware and instead tries to hide it.

BSP was primarily created to facilitate applications using bare metal. It's beneficial because it speeds up deployment by letting the user concentrate on developing algorithms rather than the finer points of hardware, register, and memory-specific implementation details.

BSP offers an abstraction for high-level programming and readable code, which simplifies working with the board.

BSP helps in reducing the chances of writing incorrect code as it is standardized and released by vendors. The Board Support Package (BSP) is popularly used not only for a start-up but also to run the embedded target processor.

Because Board Support Packages are user-customizable, users can choose which routines and drivers to include in the build according to their preferred hardware and software combinations. Any single-board computer, for instance, can be paired with any of the several graphics cards. In such a case, the Board Support Package might contain a driver for each supported graphics card. The user could specify which graphics drive needs to be included when creating the image of the Board Support Package, depending on their personal preference for hardware. You've come to the right spot if you're looking for the best BSP development companies.

Along with the Board Support Package, some suppliers also offer a root file system, a toolchain for creating programs that run on the embedded system, and utilities that must be configured according to the device.

BSP is used to assemble a custom image of the specific operating system when building a new board or development kit. One of the software packages designed to be used with an evaluation board or a particular chip is the board BSP. A few environmental variables and peripherals may be started by the BSP so they can function with the embedded operating system.

There are some specific tasks that Board Support Package performs by initializing the following.

Processor

Bus

Interrupt Controller

Clock

Configuring the segments

Run the boot loader.

RAM (random access memory) settings

Hardware parameters, compilation parameters, and operating system configuration instructions can all be found in the Board Support Package. To know more information, please subscribe to our Blog, and for any sales queries, wait no further contact us at info@siliconsignals.io

Coming soon - CH552 QT Py is a tiny 8051 board

We designed this CH552-based QT Py board before the chip shortage, but now parts are plentiful so we made some prototypes and are trying out the CH55xduino (https://github.com/DeqingSun/ch55xduino) board support package. and, it works! but watch out, its C not C++ so you can't use the huge collection of existing libraries and drivers. however, for about '40 cents' per chip, you get a 8051 with native USB that can do CDC/HID, has 4x 8-bit ADCs, hardware serial, I2C, SPI and doesn't need a crystal or a lot of passives. obviously there's down sides to such a minimal 8-bit microcontroller chip but we think it could be super fun for some very basic USB projects!

Der XIAO RP2350 im Vergleich mit dem originalen Pi Pico 2

Neben dem originalen Pi Pico 2 habe ich mir den XIAO RP2350 aus China gekauft und dieser wurde recht schnell innerhalb von 5 Tagen geliefert. (Abzüglich der üblichen Probleme mit dem Zoll.) Dieser kleine Zwerg kommt mit etwas weniger Pins daher, hat jedoch den Vorteil, dass dieser zumindest über eine fortschrittliche USB-Typ-C Schnittstelle verfügt und sofort programmiert werden kann (dazu später mehr).

Dieser kleine Mikrocontroller besitzt zusätzlich eine RGB-LED, die über GPIO22 gesteuert werden kann. Zudem kann die als USER-LED bezeichnete LED über GPIO25 angesprochen werden. Die USER-LED wird ebenso verwendet, um den aktuellen Status anzuzeigen (UART Übertragung und POWER).

Der Mikrocontroller wird wie über die Micro-USB Buchse mit dem Computer verbunden und wird dort als RP2350 Boot erkannt.

In der Arduino IDE sowie Thonny wird dieser jedoch nicht erkannt und ich musste diesen Mikrocontroller erstmal flashen. Dazu habe ich mir die UF2-Datei von der Seite https://micropython.org/download/RPI_PICO2/ geladen und auf den Mikrocontroller kopiert. Der Mikrocontroller war dazu bereits im korrekten Modus versetzt gewesen, d.h. es war das Laufwerk RP2350 im Explorer sichtbar. Nachdem der Mikrocontroller selbständig neu gestartet ist, war dieser in Thonny einsatzbereit und man kann nun diesen mit MicroPython programmieren.

Raspberry Pi Pico 2 - RP2350 geflasht für MicroPython Nachrüsten der fehlenden Bluetoothschnittstelle mit dem seriellen HC-06 Modul Zumindest kann man die fehlende Bluetoothschnittstelle mit dem seriellen Bluetoothmodul HC-06 sehr einfach nachrüsten. Es gibt auch ESP8266 Module, welche ebenso via serieller Schnittstelle angeschlossen werden können (jedoch habe ich derzeit keines zur Hand, ist aber bestellt).

Für den Aufbau der Schaltung benötigst du: - einen Raspberry Pi Pico 2* - ein Micro-USB Datenkabel* - vier Breadboardkabel*, 10 cm - eine LED* - ein Bluetoothmodul HC-06* - ein 400 Pin Breadboard* Hinweis von mir: Die mit einem Sternchen (*) markierten Links sind Affiliate-Links.

Vielen Dank für deine Unterstützung! Die Schaltung hierzu ist recht einfach, für die serielle Kommunikation benötigen wir lediglich zwei Breadboardkabel und für die Stromversorgung des Modules ebenso zwei. In meinem Fall verwende ich eine 10 mm LED, welche eine Spannungsversorgung von 3.3V hat, somit direkt mit dem Mikrocontroller verbunden werden kann (quasi ohne 220 Ohm Vorwiderstand).

Schaltung - Raspberry Pi Pico mit Bluetoothmodul HC-06 & LED Im Beitrag Raspberry Pi Pico W & Bluetooth habe ich dir erläutert, wie man das Vorgängermodell mit dem CYW43438 Chip über das HC-06 Modul Bluetoothfähig macht. Der Chip CYW43438 verfügt neben WiFi auch über Bluetooth, jedoch kam dieses erst mit einem Firmwareupdate und somit gab es eine Zeit wo der Pico W ohne Bluetooth geliefert wurde. # Import der benötigten Module # zum kommunizieren über # die serielle Schnittstelle from machine import Pin, UART # definieren der seriellen Schnittstelle # der Pi Pico verfügt über mehrere serielle Schnittellen # es wird hier die erste verwendet mit # einer Geschwindigkeit von 9600 baud uart = UART(0, 9600) # die LED ist am GPIO6 angeschlossen led = Pin(6, Pin.OUT) # starten der Endlosschleife while True: # Wenn Daten empfangen wurden, dann... if uart.any() > 0: # auslesen der Daten data = uart.read() # ausgeben der Daten auf der seriellen Schnittstelle # diese können via Putty oder # in der Shell von Thonny abgelesen werden print(data) # Wenn der gelesene Wert gleich 'on' ist, dann... if "on" in data: # aktivieren der LED led.value(1) # absenden der Zeichenkette an den Sender uart.write('LED on n') elif "off" in data: # Wenn der Wert 'off' ist, dann... # LED deaktivieren led.value(0) # absenden der Zeichenkette an den Sender print('LED off n') uart.write('LED off n') Read the full article
