Additional data lines on Proffieboard v2.2

Proffieboards

I’m looking to go beyond the four data lines on the Proffieboard v2.2 soundboard that I have on-hand & I’d like to use one of the pads such as the button 3 pad as a data 5 pad, if it is possible.

Better minds than mine will know for sure, but I imagine it would need extensive rewriting of key parts of the OS to make it work. Can you not achieve the same thing using sub-blades for your install?

That’s what I said. But for what it’s worth,

  aux2Pin = 22,                   // AUX2 button   PB4
  bladePin = 16,                  // blade control, either WS2811 or PWM PA0
  blade2Pin = 1,                  // PB10
  blade3Pin = 17,                 // PB3
  blade4Pin = 0,                  // PA4
  blade5Pin = 8,                  // PA15 (also UART)
  blade6Pin = 9,                  // PA02 (also UART)

You can use any pin that hooks up directly to the CPU to drive pixels. This includes data1-4, rx,tx and button1-3 for a total of 9 possible data lines.
