basic question: how to install?

[barnaclebill22]

You may need to install the openplotter-pypilot package to get that script.  It mostly just installs services and configures them for pypilot.  It is not required but could be helpful.

It should be possible to run "pypilot_boatimu" to only get the intertial data, but it wont push it into signalk.  For this you could just run pypilot.    I am not sure what spi probing you refer to but,  if you could post the output it would help.    Maybe it is probing for a motor controller, but you could potentially block this by blacklisting all the serial ports.

I will look into better methods for running imu only mode.

Thanks. I installed as per the wiki/workbook and the SPI errors went away. Not sure what changed but I don't want to roll back unless I need to.
When you say "install openplotter-pypilot package", what do you mean specifically? I tried "pip3 install openplotter-pypilot" and didn't get anything. pypilot (3.2.13-stable) is already installed in openplotter; as is the pypilot plugin.
Is there a list of supported IMUs anywhere? I have several; the one on my RPI uses the LSM303AGR sensor but does not appear to be supported...it doesn't show up here:
