Documentation for the machine package for the Adafruit QtPy
The QtPy comes with the UF2 bootloader already installed.
Flash your TinyGo program to the board using this command:
tinygo flash -target=qtpy [PATH TO YOUR PROGRAM]
The QtPy board should restart and then begin running your program.
If you have troubles getting your QtPy board to receive code, try this:
Now try running the tinygo flash
command as above:
tinygo flash -target=qtpy [PATH TO YOUR PROGRAM]
Once you have updated your QtPy board the first time, after that you should be able to flash it entirely from the command line.
You can use the USB port to the QtPy as a serial port. UART0
refers to this connection.
