Backplane MCU

System 0.0.8

On this sheet, in the MCUBP column, we have defined how the 48 I/Os of the backplane’s microcontroller will be used to drive our 8 rotary encoders. And now that we have plenty of I/Os to play with, we will revert to RGB illuminated knobs. As a result, each rotary encoder will require 6 I/Os:

  • Clockwise rotation
  • Counter-clockwise rotation
  • Single-pole, single-throw switch
  • Red
  • Green
  • Blue
