rp-pico - Board Support for the Raspberry Pi Pico

You should include this crate if you are writing code that you want to run on a Raspberry Pi Pico - the original launch PCB for the RP2040 chip.

This crate includes the rp2040-hal, but also configures each pin of the RP2040 chip according to how it is connected up on the Pico.


To use this crate, your Cargo.toml file should contain:

rp-pico = "0.4.0"

In your program, you will need to call rp_pico::Pins::new to create a new Pins structure. This will set up all the GPIOs for any on-board devices. See the examples folder for more details.


General Instructions

To compile an example, clone the rp-hal repository and run:

rp-hal/boards/rp-pico $ cargo build --release --example <name>

You will get an ELF file called ./target/thumbv6m-none-eabi/release/examples/<name>, where the target folder is located at the top of the rp-hal repository checkout. Normally you would also need to specify --target=thumbv6m-none-eabi but when building examples from this git repository, that is set as the default.

If you want to convert the ELF file to a UF2 and automatically copy it to the USB drive exported by the RP2040 bootloader, simply boot your board into bootloader mode and run:

rp-hal/boards/rp-pico $ cargo run --release --example <name>

If you get an error about not being able to find elf2uf2-rs, try:

$ cargo install elf2uf2-rs

then try repeating the cargo run command above.


Flashes the Pico's on-board LED on and off.


Reads a push button attached to GPIO 15 and drives the on-board LED to match it (i.e. on when pressed, off when not pressed).


Demonstrates the use of the Real-Time Interrupt-driven Concurrency Framework on the Raspberry Pi Pico.


Another LED blinking example, but using a Timer in count-down mode.


Puts out an analog 'triangle wave' on GPIO 25, using the PWM hardware.


Demonstrates handling a micro servo, using the PWM hardware.


Creates a USB Serial device on a Pico board.

The USB Serial device will print HelloWorld on start-up, and then echo any incoming characters - except that any lower-case ASCII characters are converted to the upper-case equivalent.


Creates a USB Serial device on a Pico board, but demonstrating handling interrupts when USB data arrives.


Demonstrates emulating a USB Human Input Device (HID) Mouse. The mouse cursor will jiggle up and down.


Example that shows how to use the embedded_sdmmc crate with the Raspberry Pi Pico.
