I want to use the I2C interface of the H743ZI microcontroller to communicate with the BM1422AGMV (3-axis magnetic sensor).
Code is programmed by arduino IDE, the link of code example is:
The problem is:
- This code can work in Arduino Uno board, but can not work in H743ZI.
- SCL and SDA have no signal.
- I'm not find any information about I2C connection in data sheet.
What do I need to set on the H743ZI??
Does this code be used only for the Arduino board??
Or just the board is broken??
