pw_digital_io_rp2040

pw_digital_io_rp2040 implements the pw_digital_io interface using the Raspberry Pi Pico SDK.

Setup

Use of this module requires setting up the Pico SDK for use with Pigweed. Follow the steps in Raspberry Pi Pico to get setup.

Examples

Use pw::digital_io::Rp2040DigitalIn and pw::digital_io::Rp2040DigitalInOut classes to control GPIO pins.

Example code to use GPIO pins:

#include "pw_digital_io_rp2040/digital_io.h"

using pw::digital_io::Rp2040DigitalIn;
using pw::digital_io::Rp2040DigitalInOut;

Rp2040DigitalInOut out(/*gpio_pin=*/ 15);
out.Enable();
out.SetState(pw::digital_io::State::kInactive);

Rp2040DigitalIn in(/*gpio_pin=*/ 16);
in.Enable();
auto state = in.GetState();
