Hi all, I am a new sensor user and am struggling to get my head around some of the code I’m encountering.
I’m working with a SparkFun 9DOF_Razor_IMU sensor and I was hoping to be able to set the accelerometer sampling rate at 1000Hz.
The config files states the following:
#define IMU_AG_SAMPLE_RATE 1000 // Accel/gyro sample rate Must be between 4Hz and 1kHz
However also included in the firmware is the following statement:
// Set gyro/accel sample rate: must be between 4-1000Hz
// (note: this value will be overridden by the DMP sample rate)
#define DMP_SAMPLE_RATE 100 // Logging/DMP sample rate(4-200 Hz)
I am confused why the seemingly possible 1kHz Accel sampling rate would be overwritten by the DMP sampling rate which is limited to 200Hz.
Is anyone able to assist me?
Regards, Kelly.
