Change directories into the directory with the repo
-
Connect your Pybadge to your computer using a USB cable
-
Make sure to turn on the badge, flip the switch at the top of the board next to
select
to theon
position. The screen should light up and might be showing a sine wave display (if it was not already flashed to something else). -
Run this command to compile and flash the code to your Pybadge:
If you are running Mac or Linux, or have make installed you can run the following:
make flash
otherwise run tinygo directly
tinygo flash -target pybadge .
Note: if you get a permision denied
error; please, consult this page for possible solution. You many need to restart the computer; afterward to get the group to stick.
- To display a conference logo on your badge, use one of the following targets (depending on GC for Europe, UK, or US):
make flash-gceu
make flash-gcuk
make flash-gcus
- To customize the Gobadge with your own name and information, use the
NAME
,TITLE1
, andTITLE2
variables like this:
make flash-gcus NAME="@TinyGolang" TITLE1="Go compiler" TITLE2="small places"
- 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.
๐ Congratulations! It is now a GoBadge.
