Issue on Data ready interrupt of MPU-9250

Hello,

I am a complete newbie to microprocessor and I'm trying to use InterruptIn function to get data from MPU-9250 using new data as a trigger of interrupt but I have no idea on how to a accomplish it. I have been reading a Register Map but I still don't understand how things work. I’m wondering if someone could give me any input.

I'm using Nucelo F411RE.

The MPU9250 uses I2C to communicate with the MCU, so don't use an InterruptIn for this. Instead, use a library like MPU9250AHRS which has an example program which shows you how to read the data from the sensor.

Hello,Jongboom

Thank you for your response! I have already used Mr.Winer's program and have been able to get data, but I need to use to a interrupt to control timing. The problem I have been through is that I want to make the INT pin high when a sensor has new data to be read but I don't know which register's setting to change. Sorry for my bad english :(
