TinyGo powered badge using the Adafruit Pybadge hardware.

https://www.adafruit.com/product/4200

• Install TinyGo using the instructions from https://tinygo.org

• Clone this repo

• Change directories into the directory with the repo

• Customize the file data.go with your own name and information

• Connect your Pybadge to your computer using a USB cable

• Run this command to compile and flash the code to your Pybadge:

make flash

or

tinygo flash -target pybadge .

• To display a conference logo on your badge, use of the following target:

make flash-gceu
make flash-gcuk
make flash-gcus

• Create an image with a 160x128 pixels size, copy it into cmd/assets folder.
  For the moment only jpeg images are supported.
• In cmd/main.go add the path to your file here

const (
gopherconEU22Logo = "./cmd/assets/gopherconeu-2022.jpg"
gopherconUK22Logo = "./cmd/assets/gopherconuk-2022.jpg"
gopherconUS22Logo = "./cmd/assets/gopherconus-2022.jpg"
yourPathLogoHere = "./your/path/to/the/logo"
)

• Add the corresponding flag to the conf map:

func confs() map[string]string {
	return map[string]string{
		"gceu22"    : gopherconEU22Logo,
		"gcuk22"    : gopherconUK22Logo,
		"gcus22"    : gopherconUS22Logo,
		"flagLogo"  : yourPathLogoHere,
	}
}

Add a new target to the Makefile:

flash-yourconf:
	go run cmd/main.go -conf=flagLogo
	tinygo flash -target pybadge .

You can run:

make flash-yourconf

It will use cmd/logos/logo-template.txt to generate the image into a []color.RGBA. Then it is stored in variable in logo.go file.

package main

import "image/color"

var logoRGBA = []color.RGBA{ {255, 255, 255} }

After the image has been generated, the make command will flash it to the board.

👏 Congratulations! It is now a GoBadge.
