  • There's one more option, which is pretty hardcore:

    • Create some in-line assembler to bit-bash out the display output
    • Set up PWM on a pin with a frequency of 1kHz (to enable the timer)
    • Use poke32 to set the interrupt vector table to point to your inline assembler
    • Enable interrupts for that timer.

    As I say, pretty hardcore, and probably not recommended :)
