Strange behavior I2C #2059
Description
Microcontroller stm32f401ccu6
Connecting by I2c SDA-PB7, SCL-PB6
IMU MPU-9250
This sketch
Works good
I2C device found at address 0x68 !
But when I try to use sketch
I get a message
Error initializing communication with IMU
Which says that the wire does not work.
I can't find the reason for this behaviour.
The author of the library says the reason is incorrect initialization of I2C.
Help me to understand.
