I managed to solve the problem, for some reason Wire.begin() must be called before Serial.begin(), I also had to reset the SDA and SCL pins to PB9 and PB8. My code was like this: #include <Wire.h> void setup() { Wire.setSDA(PB9); Wire.setSCL(PB8); Wire.begin(); Serial.begin(9600); Serial.println(&qu...

I'm trying to use the Arduino Wire library for the Nucleo F446RE board (STM32 boards groups 2.2.0), but I don't get any signal on the SDA and SCL, both have pullup resistors (I've tested 10k, 1k, 4k7). I've already tried to configure the SDA and SCL pins with Wire....
