Waveshare 2.13 V3 Golang driver

Working E-paper waveshare 2.13 V3 Golang driver

Due to the change of the chipset used in the waveshare 2.13 epd, the old v2 driver is not compatible. This implementation of the python drivers tries to mimic into V3 version to make it work

• Original driver : here
• Heavily inspired by This project from bestbug456

How can I try this driver?

If you are wandering whether your E-paper is compatible you can try this snippet of code.

func main() {
	e := CreateEpd()
	defer e.Close()
	defer e.Clear()
	e.Init()
	e.Clear()

	fmt.Printf("Display\n")
	e.Display(getData())
	fmt.Printf("sleeping\n")
	time.Sleep(5 * time.Second)
}

// getData return a image from the gotchi project, more info at https://github.com/GaelicThunder/Chao-Pi-Adventure
func getData() []byte {
	return []byte{255, 255, 255, 255, 255, 255, 255, 255, 255, 255, 255,
