I have a few of these, well, will have a few more over next week...

I am tweaking the design but all of them do 2A 3.3V power for many peripherals, and ALL the GPIOs for an ESP32-S3-MINI-1-N4-R2, and a single WS2812 LED.

USB-C and DC 5V-17V

They are ideal for anyone wanting to play around with these processors, whether native ESP IDF, #micropython, #arduino, or whatever.

For those not following #m68kMicroPython development, a lot has been happening rather quickly in the last couple of weeks!

There's enough support for the Toolbox now that I've been able to re-create the #Macstodon splash/loading screen with it - see below.

Big thanks to @stylus for all his hard work developing the port and making this possible!

Why Lua Beats MicroPython for Serious Embedded Devs

｢ Lua isn’t just compatible with embedded systems; the Lua ANSI C library was designed for them. Its architecture is clean, compact, and deterministic.

MicroPython, on the other hand, is a reimplementation of Python 3. It works well for many embedded use cases, but it inherits assumptions from a desktop-oriented language ｣

It's teacher Tuesday!!

If you're teaching with or learning Raspberry Pi Pico programming using #MicroPython I've just shared five introductory programming activities for BEAPER Pico that you can easily adapt to other circuits!

Check them out: https://github.com/mirobotech/BEAPER-Pico

I just published a #micropython #mqtt server and #python client for accessing a remote filesystem on a micropython device by mqtt.

See:

https://github.com/dov/upython-mqtt-file-server

Meanwhile I have used it for uploading photos to my #pimoroni #presto device.

This library solves the "grandma problem" of how to place a photo frame on grandma's mantle piece and push images to it without her interaction.

I am a sucker for opto-electronics, so got this discarded kit (ex CNN's London studio?)

Each button has a 36x24 LCD display and red+green LEDS.

Well-designed hardware: ColdFire (=68k) CPU, plenty of RAM, plenty of FLASH, serial port, ethernet etc.

Firmware ? Not so impressive, but very easy to get rid of:

Anybody can flash new firmware from ethernet: No userid, no password, all you need to know is the IP# and how they botched their CRC-16 implementation.

Now it runs #MicroPython :-)

My latest blog post: Metronalmost

https://mikecoats.com/metronalmost/

This metronome, by design, will never, ever, tick exactly once per second. This infuriating object is designed to thwart the goals of @hackaday's One Hertz Challenge contest.

I found a nice way to interact with the S0 counting bus of my three energy meters. Every single used GPIO pin gets it's own interrupt for measuring the time in between last 1->0 change. Every 15 seconds a mqtt broadcast is done to report the average consumption. In addition a one hour and 24 hour sum array is filled too. So no need for PIO operations any more.

#CC2tv #403 Vom `print()` zum #Bit

So spricht dein #Mikrocontroller
Wir zeigen, wie ein einziger #MicroPython-Befehl – `print("Hallo Welt")` – Schicht für Schicht bis zum elektrischen Signal am TX-Pin zerlegt wird. Wir starten in der Hochsprache, werfen einen Blick auf den erzeugten #Bytecode und zeigen, wie die MicroPython-VM ihn in C-Routinen übersetzt. Von dort gelangt der String über den #UART-Treiber als #ARM- #Maschinencode auf den RP2040-Prozessor

Is there anyone in the room with knowledge about #ESP32 microcontrollers?

I am playing with a #Waveshare development board that has an #AMOLED and a touchscreen, and it says it has built-in #SH8601 display driver and #FT3168 capacitive touch chip, using #QSPI and #I2C communication respectively.

https://www.waveshare.com/product/arduino/boards-kits/esp32-s3-touch-amoled-1.8.htm

It directly works in #Arduino with #C, but I am trying to make it work with #MicroPython.

Before I spend effort trying to compile it with #LVGL, I want to know if I could print a "Hello World" to the screen as is, and while my mind tells me that I need a driver, the sentence "built-in display driver using QSPI" makes me think that I could eventually use the display without code drivers, but I don't know how.

I'd love to see an example, if it's possible, or to be pointed to any resources that I can read in this regard. I am complete newbie.

Re-posts are appreciated.

Thank in advance
