This repository contains some code that I wrote for my Raspberry Pi Pico, using Microzig. The code here is relies heavily on code from the official Microzig examples.

The files in the src directory do the following:

• three_leds.zig: toggle three LEDs connected to GPIO18-20 (they don't have to be LEDs, that's just what I used)
• i2c.zig: a basic driver for sending data over I2C to an SDD1306 OLED display
• uart.zig: communicate over UART, showing different message types; this is very similar to the official Microzig example

Build

Clone the repository

$ git clone https://github.com/andrwcnln/picozig

Build the files by running zig build at the root of the project

$ zig build

The files will be in $PROJECT_ROOT/zig-out/firmware

Run

Just copy the desired .uf2 file over to your Raspberry Pi Pico when connected in BOOTSEL mode.
