Documentation for the machine package for the Waveshare RP2040-PiZero
Flashing
UF2
The Waveshare RP2040-PiZero comes with the UF2 bootloader already installed.
CLI Flashing
-
Flash your TinyGo program to the board using this command:
tinygo flash -target=waveshare-rp2040-pizero [PATH TO YOUR PROGRAM] -
The Waveshare RP2040-PiZero board should restart and then begin running your program.
Notes
You can use the USB port to the Waveshare RP2040-PiZero as a serial port.
TinyGo has support for the RP2040’s on-board Programmable Input/Output (PIO) block.
