I recently got the SEN0140 10 DOF IMU from DFRobot. I'm trying to upload a program to an Arduino Mega 2560 that will output the accelerometer, gyroscope and magnetometer data to an SD Card. This IMU uses an I2C interface, which has been my main problem. I cannot figure out how to receive the data from all three sensors simultaneously. Thanks to projects likethis I have been able to receive the accelerometer and magnetometer data in Simulink to a scope, but not at the same time. At this point I'm completely lost. Any advice?
