IMU calibration process:

// Note* the Longfly dRehm uses a MPU6050 imu

1) Command + F the function "Calculate_IMU_error" within the dRehmflight code, uncomment it so that it is active. 

2) Lay the Longfly dRehm board on a flat surface with the teensy installed in it. Make sure that no other Print-functions are uncommented, then upload the code with the "Calculate_IMU_error" function active. You should see a list of values in the serial monitor that looks like this:

float AccErrorX = *****;
float AccErrorY = *****;
float AccErrorZ = *****;
float GyroErrorX = *****;
float GyroErrorY = *****;
float GyroErrorZ = *****;
Paste these values in user specified variables section and comment out calculate_IMU_error() in void setup.



Where each ***** is replaced with an decimal value. Command + F "User-specified Variables" within the code and delete the old AccError and GyroError values, replace them with the copy and pasted values from the serial monitor.

 

3) Comment out "Calculate_IMU_error" and flash the teensy4.0. Your IMU is now calibrated.
