Re: Timer handler won't work when calling callback function inside the handler

MicroPython is open source. See https://github.com/micropython/micropython/blob/master/ports/stm32/timer.c . Thanks so much, I didn't know stm32 folder is meant for Pyboard, this explains a lot! Nevertheless, I have investigate a little while and realise all ports have different way of implementing...

Re: Timer handler won't work when calling callback function inside the handler

I notice you use mp_call_function_0(self->callback); but the callback is a lambda that takes one argument. So this will always fail (although it doesn't explain why your board locks up, but have you confirmed that NLR is definitely working correctly in your port) Thanks for the reply, yes I used "m...

Re: Timer handler won't work when calling callback function inside the handler

I'm not sure about your Python code. Here is what I had to do to make this run on a Pyboard: >>> from machine import Timer >>> t = Timer(-1) >>> t.init(period=1000, mode=Timer.PERIODIC, callback=lambda x : print('test')) Please don't post the same query under multiple forum headings. [co-mod] Hi, t...

Timer handler won't work when calling callback function inside the handler

Hi I am currently porting MicroPython to Realtek’s RTL8722 WiFi+ BLE dev. board, and it has been mostly done except the Timer module which takes in a callback function but never returns. here is the C code I wrote for Timer: STATIC mp_obj_t timer_start(mp_uint_t n_args, const mp_obj_t *args) { enum ...

Re: What is minimal requirement to have REPL running?

I think that the minimal requirements are to have the heap initialized, and have the mp_hal functions related to the uart implemented. This is essentially what the minimal port does: https://github.com/micropython/micropython/tree/master/ports/minimal Thanks!! Just as I suspected, I got heap and ua...

What is minimal requirement to have REPL running?

Hi! I am currently working on porting micropython to a new board. I came to the stage where my firmware compilation was ok, safely uploaded and having logs printed, but just couldn't see REPL (three ">") running. I am new to project of this magnitude and complexity, so any information or direction i...
