I am trying to imlpement serial protocol form PC to pyboard as well. Here are my intermediate findings: 1) RAW REPL console is started with Ctrl+d (translate that into bytes) and finished with Ctrl+b (works like Enter in normal REPL) 2) on my mac in other embedded projects, usually \n does not cut i...

Thank you for hints.

This is a question of "how to debug with breakpoints".

Minicom, screen or serial tools are not going to cut it., moreover, the REPL freezes because of a code bug, which is hard to reproduce, because random.

Does anybody debug C / micropython code with breakpoints ?

My pyboard v3 with current code causes the following: REPL "freezes" when in minicom serial terminal on mac and becomes unresponsive. It happens randomly, from 1 minute to 3 hours range. It happens in all serial console tools. The only solution is to close the serial port and re-open, sometimes hard...

The plan: - pressing USR button resets the board - press&hold for 2 seconds powers off the board When a pin is activated, external IC cuts-off the main power to processor. The issue: SDcard is still plugged in and the OS comp...

Does it mean the garbage collector should be active from the start? I usually check free memory with: import pyb pyb.info() However, after each REPL command, the free memory decreases, until "Out of Memory". Tried to solve this with garbage collector and it works only in manual mode: import gc # low...

Thank you,
great answer, I will try not to code at 3am again.

Will dig deeper into interrupt handling and callbacks.

Can someone confirm this behavior, or is it just me?
This comes after having 260 lines of code in main.py, so maybe it is just my implementation...

Thank you.

Any idea where I might start searching for an error in this code? sw = pyb.Switch() def BTN_callback(): pyb.udelay(4000) pyb.LED(1).toggle sw.callback(BTN_callback) >>> Uncaught exception in ExtInt interrupt handler line 0 MemoryError: sw.callback(lambda: does work, however, what if one wants to imp...
