PWM on Trinket M0

[obiben]

Hardware: Trinket M0
Bootloader: 3.10.0
CircuitPython: 6.0.1

I'm having trouble using PWM on Trinket M0.

Examples point me towards a library called pulsio, but I cannot find it anywhere, including the CircuitPython 6 library bundle.

pulseio is a built-in (C) module, but is not available on SAMD21 boards that don't have external flash chips ("Express" boards), for space reasons. [EDIT: it is on the Trinket and many other small builds]

You could make a custom build, at the expense of removing some other things that you might not need. Or just switch to a more capable Express board.

What's on which board: https://circuitpython.readthedocs.io/en/latest/shared-bindings/support_matrix.html

Thanks @dhalbert, that matrix clearly shows I'm either dyslexic or an idiot. pulseio is included on the M0, pulsio just doesn't exist!
