Tried these two below on micropython esp32 but dont seem to work. I can get macOS to see it as a keyboard but can't send any keystrokes.
- example here: https://github.com/micropython/micropython/pull/6559/files

how to launch an applescript from a keyboard shortcut? https://apple.stackexchange.com/a/276839
Had a problem with making the zwift initial laucher window click the "Let's Go" button, had to hack around it by clicking the menu items as here: https://apple.stackexchange.com/questions/350940/use-applescript-to-raise-and-focus-on-window

seems like tasko would freeze up the MCU randomly :/
Found this repo and pulled the trackball module from it: https://github.com/mchobby/esp8266-upy/blob/master/trackball/lib/trackball.py Had to fix it up a bit to get running on esp32 micropython, not sure if the interrupt stuff works yet but should be easy enough to get going. Took a little bit of trial and error to figure out the i2c bus, had to define the pins D22 and D23 in the i2c constructor.
Then rewrote it for circuitpython and created the pimoroni_trackball.py module. It was easy once I figured out the adafruit_register module to read and write to i2c registers.
