Que? what schematic ?

What PicoMite VGA are you wanting to interface a controller with ?

For digital joystick and 6 buttons your "obvious" choices are:

- 12-bit shift register (probably 2 x 8-bit chained together), requires 3 GPIO, e.g. SNES
- I2C, e.g. Wii Classic or Mick's controller of the day, this option will also support analog joysticks
- drive 12 GPIO pins directly (Atari joystick does 5, Game*Mite does 8)

The currently distributed PETSCII Robots for PicoMite has Wii Classic support, but not SNES support, easy enough to add, but I don't actually have a working controller ... going to bother @Mixtel90 (or eBay) in the New Year.

Best wishes,

Tom
