An Uno and Golang

Recently, I saw a posting about installing a light weight version of Golang on an Arduino Uno, and I was hooked. Overall, it’s beautiful, and takes me back to the 1980s when electronics was fun:

And so, I don’t want to develop using Sketch and with the default GUI, so it was off to Golang for me [here]:

And, as I have Mac, it’s an easy install:

$ brew tap tinygo-org/tools
$ brew install tinygo
$ brew tap osx-cross/avr
$ brew install avr-gcc
$ brew install avrdude
$ git clone --recursive https://github.com/tinygo-org/tinygo.git
$ cd tinygo
tinygo$ brew install llvm
tinygo$ go install

And so with the code of:

package main
// This is the most minimal blinky example and should run almost everywhere.
import (
 “machine”
 “time”
)
func main() {
 led := machine.LED
 led.Configure(machine.PinConfig{Mode: machine.PinOutput})
 for {
 led.Low()
 time.Sleep(time.Millisecond * 500)
