Remove dependency on wiringpi

[mgrouch]

WiringPi is not working on pi5 and bookworm. wiringPi is no longer maintained and is deprecated

thanks

[seandepagnier]

wiringpi should be optional. Are you getting an error message from it?

[mgrouch]

I’ll try without wiring pi. Thanks

[mgrouch]

It runs without wiringpi on bookworm. (So far tested on pi4, not - pi5). It gets heading from IMU fine.

However pypilot_calibration fails on start under bookworm:

user@lysmarine:~ $ pypilot_calibration

    sys.exit(load_entry_point('pypilot==0.36', 'console_scripts', 'pypilot_calibration')())

    raise error.NullFunctionError(

could it be that glut or at least glut in python is broken?

[seandepagnier]

Maybe it works now?

[mgrouch]

It goes further but now fails with this:

I am going to need to reproduce this on my end to fix I think...

[mgrouch]

@seandepagnier

easy way to reproduce is just burn latest test bookworm image of BBN OS and load it on pi4.

https://cloudsmith.io/~bbn-projects/repos/bbn-repo/packages/

and just start pypilot_calibration from command line.
