(Work in progress)

Code to create a Function Generator using a RPI pico.

  • Development + Debug environment:
    • VSCode on Win 7
    • Picoprobe running on 2nd RPI pico
    • OpenOCD and GDB
  • Rotary encoder input using State Machine 0
  • Onboard LED flashing using State Machine 1
  • Nixie tube display
    • Multiplexed to reduce hardware
    • 170 volt PSU for tubes created from 4 x 1.5v batteries + custom SMPS
  • Software generated table of Sine wave values
  • 5 bit R2R ADC creating Sine wave output for oscilloscope
