pico

Support for Raspberry PI microcontrollers

Embedded Go supports the RP2350 family, aka Pico 2 (there is no support for RP2040).

Your program will run on both ARM cores (the RISCV mode is not supported).

Getting started

1. Install the Embedded Go toolchain.

   go install github.com/embeddedgo/dl/go1.24.5-embedded@latest
   go1.24.5-embedded download
   

2. Install egtool.

   go install github.com/embeddedgo/tools/egtool@latest
   

3. Create a project directory containing the main.go file with your first Go program for RPi Pico 2.

   package main
   
   import (
   	"time"
   
   	"github.com/embeddedgo/pico/devboard/pico2/board/leds"
   )
   
   func main() {
   	for {
   		leds.User.Toggle()
   		time.Sleep(time.Second/2)
   	}
   }
   

4. Initialize your project.

   go mod init firstprog
   go mod tidy
   

5. Copy the go.env file suitable for your board (here is one for Pico 2 and another one for a board with 16 MB flash).

6. Compile your first program.

   export GOENV=go.env
   go build
   

   or

   GOENV=go.env go build
   

   or

   egtool build
   

   The last one is like GOENV=go.env go build but looks for the go.env file up the current module directory tree.

7. Connect your Pico 2 to your computer in the BOOT mode (press the onboard button while connecting it to the USB).

8. Load and run.

   egtool load
