Not sure what I accomplished with this...
An example of getting the Pico to control the Atari 7800... and trying to get my Bluetooth for free.
Basically, I'm just trying to learn how to use the Pico to control the Atari while I wait for David to update the schematic for the joystick PCB.
This will also work with a standard SNES controller. Not counting the controller, or the wires, this is about $6 in parts including the Pico.
And, unlike the Pi Zero with an OS that I was previously working with, this boots instantly. The only thing that sucks is waiting for the Hyperkin Bluetooth to pair.
Where I was using Python before, this is written in Pico SDK for C.
Anyway, check out the video.
