RP2xxxPIO: writing PIO programs inline in Swift

Hi everyone! I’d like to share RP2xxxPIO, a Swift DSL for writing PIO programs directly inside your Embedded Swift firmware. PIO is programmable I/O hardware on Raspberry Pi’s RP2040 and RP2350 microcontrollers. Think of it as small processors dedicated to reading and writing pins with precise timing, independently of the main CPU. It’s useful for things like custom serial interfaces, LED drivers, and digital audio. Instead of writing a separate assembly file, you can write this: import RP2x...
