The PIO is something unique in the microcontroller world.

Since rustc 1.61.The microcontroller chip (RP2040) used on the Pico was designed by the Raspberry Pi foundation and features a dual-core Arm Cortex-M0+ processor with 264KB internal RAM, support for up to 16MB of off-chip Flash and a wide range of flexible I/O options which includes I2C, SPI, and Programmable I/O (PIO). Import the rust_gpiozero crate, and program an LED to alternate between on and off every second: use rust_gpiozero::* īe sure to add the dependency to the Cargo.toml file: Start by creating a new Rust project, and opening the main.rs file in your favourite text editor: my-pc:~ $ cargo new blink Linker = '/rpi_tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc' Tell Cargo to use a specific linker version for your target: Specify the Linkerĭownload the raspberrypi/tools repository into a directory named rpi_tools: my-pc:~ $ git clone $HOME/rpi_toolsĮdit the ~/.cargo/config file using your favourite text editor: my_pc:~ $ sudo nano ~/.cargo/config Use rustup to install the necessary target for your Raspberry Pi: my-pc$ rustup add target arm-unknown-linux-gnueabihfĪppendix for more information about targets in Rust. How to Set Up Cross Compilation Install the Target Complete the CircuitĬonnect negative to ground, and positive to BCM pin 17 as shown below: Once that is done, you can insert the SD card into the Raspberry Pi, and power it up. This is a headless distribution, which means it does not come with a GUI. Use the Raspberry Pi Imager which can be downloaded from the Raspberry Pi Software Webpage.Ī distribution I'd suggest is Raspberry Pi OS Lite. How to Code a Text-to-Morse-Code Translator.How to Program an Embedded 'Hello World'.

Starting with an embedded 'Hello World' equivalent, and advancing to a text-to-morse-code translator, this article will walk you through the process. Using a Raspberry Pi Zero W, you can quickly get up and running with embedded Rust. Embedded programming in Rust requires a whole new knowledge base.
