Arduino for STM32

You can also do the same in the new version of the Arduino IDE, but the folder you need to access is more hidden. You can find more information in the *Board platforms and cores* section at the following link:

I am using a Blue Pill STM32103FC8T6 for flight control of a drone and an MPU6050 as an IMU connected to the I2C2 port (PB10-SCL and PB11-SDA).

With this code everything works normally:
#include <SoftWire.h>
SoftWire HWire(PB10, PB11, I2C_FAST_MODE);

With this code the Blue Pill crashes after ...

I also had the same problem, with exactly the same hardware (Blue Pill STM32F103C8T6 and an MPU6050).

If it is connected to the I2C1 port it works correctly with the Wire.h library, when connected to the I2C2 port (PB11 - SDA and PB10 - SCL) and using TwoWire the code crashes after a few seconds ...

A few months ago, I bought a Blue Pill board and conducted several tests with it, always using the Arduino IDE on a breadboard. Today, I wanted to create a more final project, so I used a universal PCB. After finishing it and double-checking all the connections, I attempted to upload a program and ...
