Hi again,

on my LisaM the IMU is on the downside.

He all
thx 4 the answer

Stupid question to LisaM: Has the Aspirin to be upside or downside? ;-) The sign of the Z-Axis on the Aspirin shows a circle with a dot, so I was guessing that the IMU should be on top.

I managed to get my RAW datas by using the normal AP firmware and changing the telemetry mode in the GCS Settings to RAW.
I got some values out of the script. See attachment.

The PFD is still rotating.....

Terminal output:

I got my File. But an idea: Perhaps the test program doesn't support
the xbee api? Or is it transparent? If it is using the api i would
suggest to connect directly to the UART.

Good luck

Hi all
Has anyone successfully created a Aspirin IMU calibration file
according to this tutorial?

I've never received the calibration file from jobyrobotics so I
tried to create my own.

I tried "test_imu_aspirin" on lisa_m_1.0 board but then the Xbee
gets no data.

Any hint?

Thx Bruzzlee
