This small project is based on this article by Anders
Holmberg, in which he describes how to call C functions defined in
the Pico SDK from Zig. This program only reads the signal input from GPIO 15
on a Raspberry Pi Pico (W) and prints out if GPIO 15 is set or not. I made a personal addition to the build.zig file
to get the Pico SDK path environment variable from an .env file.
# .env
PICO_SDK_PATH=/path/to/your/pico-sdkThe GPIO 15 pin can be connected an removed to see the output difference in the program.
