Using tinyGo on an Adafruit ItsyBitsy M0 board #Golang #tinyGo #Microcontrollers #Adafruit @Adafruit @DeadProgram @tingGolang

User LarryP in the Adafruit forums writes about experiencing the use of tinyGo to program an Adafruit ItsyBitsy M0 microcontroller.

I’m pleased to report success installing and testing tinyGo ( on an Itsy Bitsy M0. Just blinking the red LED, but I find golang on bare silicon pretty promising!

A few key details:

The #tinygo channel of is *invaluable*. I got help from the compiler developer and another helpful expert; can’t beat that!

FYI, the key help was the (unintuitive-to-me-at-least) need to unset both GOROOT and GOPATH to get tinygo to work

What is tinyGo?

TinyGo ( lets you run Go directly on microcontrollers.

TinyGo has support for 14 different boards such as the Arduino Uno/Adafruit Metro, Adafruit Circuit Playground Express, Adafruit Feather M0, Adafruit Trinket M0, Adafruit ItsyBitsy M0, and BBC micro:bit. Click to see the supported hardware.

LarryP points to this demo video  (below) at FOSDEM discussing tinyGo. Great job LarryP!
