PlatformIO VS circuitpython

For the ESP32 in read mode, we've successfully developed a project using PlatformIO that accepts the key during build time and stores it in memory.

Check out Zephyr OS and Platform IO. Zephyr is part of the Linux foundation and has similarities to Linux with how it performs hardware abstraction (device tree). Platform IO integrates with other frameworks including mbed and Arduino.

PlatformIO together with avr-stub can be used to do source level debugging but there are some caveats.

Look into https://platformio.org/, it can abstract over a few RTOSes, and can show you which OSes work with which chips/boards.

If the HW looks like it works, you could also try alternate programming software. (e.g. TinyGo or PlatformIO)

You might have better luck with PlatformIO than the Arduino IDE; it's better at automatically choosing the serial port, though I can't say I've used it under Windows.

My other suggestion takes more work but will make your life oh so much better. Professionally I have used and highly recommend. https://platformio.org/ which is free!

Will you be doing embedded Linux? Embedded RTOS? Bare metal? Microcontrollers? SoC (say, FPGA with a hard processor core)?

You can do a lot with QEMU. https://bootlin.com/ has a lot of great, free training material.

https://bootlin.com/doc/training/embedded-linux-qemu/embedde...

is one of my favorites.

Learning to cross-compile, do embedded debugging, the process of booting an embedded system (which varies depending on the answers to the above questions), learning how to read a technical reference for the processor you’re using as well as for peripherals you’re likely to interact with - SPI, i2c, UART, maybe PCIe, are all handy skills. Learn a bit about JTAG, hardware, reading schematics, etc. Even being able solder is helpful.

There may be books (I had a great embedded Linux book when I started) but there are lots of online materials too. Check out https://platformio.org/

There are fun embedded boards and projects for microcontrollers too - micropython on an rpi pico, tinygo, eLua, etc.

As another point for those interested, it (to my knowledge) is currently the ONLY implementation of a scoring machine that the firmware for the device is written in Circuit Python. which gives this unit an advantage when it comes to any and all multi tasking that the unit may need to do.

The barrier to entry has never been lower. Last night I prototyped some code in Python on my Mac to talk to a Bluetooth peripheral, and then had ChatGPT translate it to Arduino C++ code for a $5 ESP32 which mostly worked on the first go.

You can even run Python on microcontrollers these days. See Adafruit's https://circuitpython.org for which they publish modules for many (almost all?) of the sensors they sell. The modern microcontroller frameworks hide much of the complexity of Wi-Fi, Bluetooth, filesystems, etc. so you can do complicated things with minimal effort. You can really cobble something together in an afternoon.

The Pico runs CircuitPython and uses Adafruit's HID library to emulate a keyboard. It's also possible to emulate a mouse and a gamepad (there are some experiments for gamepad emulation in experiments).

Asked your question in the adafruit discord and they said there's no HT1632c library for circuit python yet. There is a library for micropython. You can request to have it ported from the Micropython library I linked to by opening a feature request in the Circuit Python Github. That would be your best option for now or attempt to port the library yourself.

Microcontrollers can run Python now https://circuitpython.org/

I'm aware of two versions of Python for microcontrollers. Micro Python and Circuit Python

I tried to look in https://github.com/adafruit/circuitpython/tree/main/shared-bindings at audiocore, audioio, an audiomixer looking for a way to access the sample counter manually but I have no clue what I'm looking at :(

Try CircuitPython 8.0.3. The commit log has a couple networking changes for the Pico. My MQTT client seems to have fewer connection issues though they could be a fluke https://github.com/adafruit/circuitpython/compare/8.0.2...8.0.3
