Jimmo, I followed your advice about testing Pin B10 in mode "OPEN_DRAIN" and found that was finally a connection problem. I used a small low cost logic analyser with Sigrok/PulseView and observed that Pin B10 was always at level zero. I read again the documentation about NucleoWB55 board and found i...

I performed some complementary tests using micropython tagged v1.13 (and not daily version). I compile STM32 port with BOARD=NUCLEO_WB55 with mpconfigboard.h including the I2C3 configuration : #define MICROPY_HW_I2C3_SCL (pin_C0) // Arduino A0, pin 28 on CN7 #define MICROPY_HW_I2C3_SDA (pin_C1) // A...

Thank you jimmo for your response.
I will test your solution as soon as I have the board (left at my work this week).
Best Regards.

Hello everybody, It's my first post on this forum. I encounter some difficulties to use I2C bus using B10 and B11 pins on a NUCLEO-WB55 board and a custom STM32WB55 board. I'm using MicroPython version v1.13-94-g817b89a10-dirty (NUCLEO-WB55 port). Using NUCLEO-WB55 board and an I2C MPU device (BMP28...
