MicroPython Forum (Archive)

I did this a few months ago for a personal project: https://github.com/AsensioL/smbus2/blob/master/smbus2/smbus2.py I only recently got a chance to upload it. Check the last 2 commits. In the most recent one I add some support for the existing machine.i2c functions. Maybe it can help. Good luck Edit...

This is what has worked for me in the past on STM32 L4s and F0s: import pyb timer2 = pyb.Timer(2, freq=1000) ch1 = timer2.channel(1, pyb.Timer.PWM, pin=pyb.Pin.board.PA0, pulse_width_percent=50) Note that, the information about which pins are connected to each combination of Timer+Channel is availab...

After a few weeks of work, I finally got the STM32 G0 port working on the NUCLEO_G0B1RE.
I will be working over the next few days to make it available for everyone.
I haven't done this before, so any help/guidance would be greatly appreciated.

I found the issue.
I was copying the stm32g0xx_hal_conf_base.h too closely from the template provided by ST.

The LL UART headers are normally imported through stm32##_hal_conf_base.h.

Hi, I am working on porting the MicroPython to the STM32G0B1 Nucleo64 board (now that we finally have a 512 KB flash ROM). After several days, I have gotten stuck in the UART/USART module ... CC uart.c arm-none-eabi-gcc -I. -I../.. -Ibuild-NUCLEO_G0B1RE -I../../lib/cmsis/inc -I../../lib/stm32lib/CMS...

Hi,
There is a new 512 KB of flash STM32 G0 MCU (see NUCLEO-G0B1RE).
Are there any hard limitations that would prevent me from getting MicroPython running on it?

Thank you
