Hi,

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.

@Li-YiFan Thank you for the quick response, I solved the problem. The issue was realated to the FTDI converter I was using, I tried with another one and it worked.
I uploaded the IMU app on the openIMU with the ST-Link and this is what I get from Nav-View:
I can also connect to the unit using the Python server and now I can see data from ANS.

Hello everyone,
I have a brand new IMU 300RI Evaluation kit but I'm facing with some problems. As you suggest, I connected the IMU to my laptop with the ST-Link in order to save the .bin file, but I didn't menage to read data from the serial port through RS-232 yet.

I'm connecting pin 2, 3 and 5 of the RS-232 db9 connector to an FTDI232 in order to convert serial data to USB. The evk is powered with a 9V battery.

When I run the python server it is continuosly scannig the same COM port without establishing any connection.

I also tried to read data using NAV-VIEW 3, the bar on the bottom says that the IMU is connected without sending any packets, but atfer a while (~5 sec) the bar becomes red.

Am I doing something wrong? Thank you in advance.
