Flashing
UF2
The Sparkfun Thing Plus RP2040 comes with the UF2 bootloader already installed.
CLI Flashing
-
Flash your TinyGo program to the board using this command:
tinygo flash -target=thingplus-rp2040 [PATH TO YOUR PROGRAM] -
The Thing Plus RP2040 board should restart and run your program.
Troubleshooting
Any troubleshooting tips go here.
Notes
You can use the USB port to the Thing Plus RP2040 as a serial port.
The Neopixel LED and the SD Card are supported by tinygo drivers
TinyGo has support for the RP2040’s on-board Programmable Input/Output (PIO) block.
