<![CDATA[Increasing angular rate data range on OpenIMU300RI]]>Hello,
We've been using the OpenIMU300RI for taking some measurements. We're interested in increasing the angular rate range from +/- 250 deg/s to closer to the stated range of +/- 400 deg/s. We're currently using the 210630-152704-VG_AHRS project and I can find the 250 deg/s limit in UserMessagingCAN.c. Are there any other modifications I will have to make to the FW on this? Concerned I'm missing something with filtering or some other subfunction.

I think the range was 400 dps in default IMU App before you updated to VG_AHRS App, right?

Assuming you check data in 'a1' or 'a2' packet via RS232, could you please switch 'z1' or 's1' packet to see the rate range?

Say if I wanted to increase the range to 1000 deg/s and subsequently the resolution to 32.8 deg/s/bit would that work or is there a fundamental limit to the gyro's output?
