7.5inch e-Paper
This is an interface for the Waveshare 7.5inch e-paper display (wiki).
The GPIO and SPI communication is handled by the awesome Periph.io package; no CGO or other dependecy needed.
Tested on Raspberry Pi 3B / 3B+ with Raspbian Stretch.
For more information please check the examples and doc folders.
Installation:
go get -u github.com/gandaldf/rpi/
Load an image:
func main() {
log.Println("Starting...")
epd, _ := epd7in5.New("P1_22", "P1_24", "P1_11", "P1_18")
log.Println("Initializing the display...")
epd.Init()
log.Println("Clearing...")
epd.Clear()
// Test image
log.Println("Opening test image...")
imgFile, err := os.Open("mypic.png")
if err != nil {
log.Panic(err)
}
defer imgFile.Close()
img, err := png.Decode(imgFile)
if err != nil {
log.Panic(err)
}
log.Println("Displaying test image...")
epd.Display(epd.Convert(img))
}
