I'm still working with IMU300RI evk, but now I want to use it as an AHRS in order to obtain yaw measurements. I downloaded the Custom Example from the VS Acienna's OpenIMU Platform (OpenIMU 300RI/VG_AHRS), then I upgraded the firmware using the ST-Link. I tried to read output data from the serial port through RS-232, but when I select the "a1" or "a2" packet from ANS even acceleration data look freezed.
I get the same results even if I upgrade the firmware directly from ANS (https://developers.aceinna.com/code/apps) by choosing AHRS_testing app (PUBLIC apps page).
Is there something missing or wrong? Should I calibrate the magnetometer before? If so, how can I do that without using CAN messages? Thank you.
