Function Generator on a RP2040.

  • Features:

    • Direct Digital Synthesis (DDS) Function Generator
    • Independant control of either channel through Putty terminal session over USB port
    • Dual 8 bit R-2R Digital to Analog converter
    • 1Hz => 1MHz frequency range.
    • X-Y mode for Analog clock
    • Variable output level 0=>100%
    • External, 3 digit, SPI display
    • Target device = Pico (also works on Pimoroni PGA2040)

  • Limitations:

    • USB serial requires Windows (10 or later)
    • Phase sync mechanism not effective at high frequencies
    • Target device must be overclocked for 1MHz operation

Two independanty controled, phase locked, DMA channels...
