Example Zig project for the Raspberry Pi Pico microcontroller.

To build the firmware:

zig build

The firmware will be placed in zig-out/bin.

While you could upload code the USB bootloader, it's more fun to do everything from zig instead!

You will need:

1. A Raspberry Pi Pico.
2. A Raspberry Pi Debug Probe or a second Pico running picoprobe.
3. An installation of OpenOCD.
4. An installation of the GNU ARM embedded toolchain for arm-none-eabi-gdb.

Connect your hardware up as follows:

Then run:

zig build xrun

This will flash the firmware onto your device, then monitor for RTT output. You should see:

hello world

Printed to the terminal.
