Lichtspiele

Letzte Woche habe ich renoviert, denn mein Sohn sollte in das Zimmer seiner Schwester umziehen die nun bei ihrem Freund wohnt. Und ein Wunsch des Sohnes war ein LED-Streifen, im alten Zimmer hatten wir einen billigen Streifen aus dem Baumarkt direkt an sein Hochbett geklebt, für das neue Zimmer hatte ich aber besseres im Sinn.

Proof of Concept

If you've ever played around with TI microcontrollers, you've probably had to use the Code Composer Studio, which is fine and all, but I found out recently they made their own open source C compiler.

It's nice to know that they not only have a compiler I can use (meaning I'm not locked into using an IDE), but that it's also on the AUR!
(`yay -S msp430-elf-binutils msp430-elf-gcc msp430-elf-gdb` :-) )

I am ALL for #AI and #Claude and #GPT, etc. I do however, in my free time outside of work, school and creating STEM tutorials to help the next generation, believe that spending time in pure #Assembler in a bare-metal #Embedded #microcontroller will help you understand #Computer #Science in a way that can help you drive the future in #technology. I have and will continue to post pure Assembler drivers to help others achieve this utilizing #Arduino and #STM32 products.

If i would lile to attach some sort of keyboard onto an microcontroller what are my options? #microcontroller #electronics #diy

I have something terrible to admit... until today I never have done something with a microcontroller (if you ignore some tinkering with the Raspberry Pi Pico and flashing Meshtastic nodes).

Today I compiled the blinking example and flashed it to the ESP32C3 - easy thanks to these guides:

docs.espressif.com/projects/es

or

wiki.seeedstudio.com/XIAO_ESP3

I added a lithium battery which was quite easy. Next step: Charging by solar panel ☀️

#ESP32 #Microcontroller

A small breadboard with a small ESP32C3 microcontroller attached to it. Instead of a USB-C cable a lithium battery is attached with two cables. On The breadboard there is also a blinking LED and a resistor for the LED.

The microcontroller is running the ESP32 blinking example. It's just a picture so you can not see it blinking but at the moment I took the picture the LED was turned on.

Oh joy, another flavor of pretending to revolutionize the world by squeezing itself onto a . 🦾🔧 AtomVM: because nothing says "cutting-edge" like running a "limited but functional" subset of decades-old . 🕰️💡

7-Segment-Anzeige Grove TM1637 mit #Microcontroller NodeMCU LoLin V3 #ESP8266. Es wird über WiFi eine Verbindung ins Internet aufbebaut und von einem NTP-Server die aktuelle Uhrzeit geholt. Danach zählt der Prozessor selbst weiter und zeigt die Uhrzeit an.
Nachdem es technisch funktioniert hat, habe ich selbst aus Klemmbausteinen ein würfel-förmiges Gehäuse gebaut. #diy

Eine Digitalanzeige in einem würfel-förmigen Gehäuse aus türkisen Klemmbausteinen zeigt die Uhrzeit an (09:17).Eine Digitalanzeige in einem würfel-förmigen Gehäuse aus türkisen Klemmbausteinen zeigt die Uhrzeit an, Im Hintergrund rosa Blüten von Pfingstrosen.

Inspired by ‪Youtube's Patt Vira‬, I implemented the Reaction Diffusion algorithm in C++ on my testbed for my 64x64 matrix. Next step is to port this to my #esp32 #microcontroller and have it output directly on the #HUB75E #LED Matrix display.

In my implementation, I have three different rendering modes

Every 0.5 seconds I add/subtract a bit of B value to keep the sim alive, and reset the entire thing if the balance goes over 50%

Sometimes I hate projects! I wrote a PS/2 host for a Microcontroller. I have a logic analyzer that even delivers output ... but this god damn trackpad doesn't send coordinates -.-

The final #Zephyr episode is out today! Zephyr works with "boards" and creating a custom board definition can be a pain. But I've got you covered! Check out the full video to learn more 📺

Do you know an low power #SBC which has got both an #AP(Application Processor) and an #MCU(micro controller) and TRMs(Technical reference manual) are available in English in the public?

I don't need something fancy. A Cortex-A7 for the AP with at least 128MB RAM is enough. #riscv is okay too.

The only one I know is #milkvduo. The SoC has got an application processor(either RISC-V or 1xCortex-A53), and two MCUs.

Also I want the SBC to have #Wifi.

Also I want something cheap. not more than 25 USD.

I want use it to build a #customkeyboard which could also act as a micro PC:

There don't seem to be many RF modules that use the newish Semtech LR1121 IC. And even fewer that don't have a built-in microcontroller, but Murata does make one (they call it a 2GT). I don't like LoRa modules with micros in them, if there's a Semtech chip inside I'd prefer to talk to it directly.

Embedded folk, I have a question: Is the only point of STM32 dual-bank flash the ability to erase and write one partition without blocking execution? Is that it?

There aren't a lot of applications where that is all that important, so I was kinda hoping it was more impressive. Did I miss something else about it?

A few years ago, I started wondering if there is a way to program an AVR microcontroller without the Arduino IDE which is slow on older computers that I have. This was the starting point for the projects ucmf and yauclib:

While ucmf is a framework for compiling microcontroller projects similar to CMake, yauclib is for hardware abstraction similar to the Arduino software library. Both are in development and only support a few AVR microcontrollers so far (and Arduinos based on them).

I consider ucmf to be ready to use. yauclib still needs a lot of work, especially drivers and hardware-independent interrupt handling mechanisms.

The code for both projects is on Codeberg:
