ICM-20948 (QWIIC) setup or standard i2c - esm - 2021-06-14
I am trying to configure my pilot with an i2c ICM-20948 imu, but I am not having any luck. I initially tried to do so through the Pican-M QWIIC connection, and then by trying a standard i2c connection with jumper wires. I have seen some previous post about this being added soon, but have also seen that this is one of the IMUs of preference for Pypilot. The system will not recognize the sensor. Does anyone have suggestions, or have successfully interfaced this? Thanks in advance for your help.

what does "i2cdetect -y 1" show?

It shows 69

well it works at 0x68, the code should support either 0x68 or 0x69
Can you run rtimulibdrive demos? It may be your version of rtimulib2 is not new enought

I am getting this back:

I tried to update the latest RTIMULib but richards-tech is inactive now

You must use this repository:
https://github.com/seandepagnier/RTIMULib2
try rtimulibdrive

Hi Sean I ran the RTIMULib2, and I can see the sensor's values, however, when opening Pypilot in openplotter, the IMU is still not detecting the ICM-20948 to calibrate.

So, rtimulibdrive is working ok?
Ensure no other program is using the device, and try running "pypilot_boatimu" from the console. Please include the output from the console.

Yes rtimulibdrive is working.

you must already be running pypilot
perhaps the two processes conflict?
what does "ps aux | grep python" show you?
