9DoF Razor IMU - Just Poll Accelerometer

Sensors Environmental
1

Hello,

I have the 9DoF Razor IMU.

I am fairly confused. The accelerometer sample rate can be set up to 1khz, but the FIFO for the DMP is at max, 200 hz.

How do I go about polling the accelerometer at 1khz? I don’t need the fancy DMP.

Thanks.

Hi Platypus86.

The example firmware that comes with the board is rate limited to 100Hz and can’t go faster than that. You’d need to write your own firmware to go faster than 100Hz and unfortunately SparkFun doesn’t offer assistance with code. You might be able to find another forum user that would be willing to help you with that though.
