epd
Interface to ePaper HAT
INSTALL
This assumes you are using RaspberryPi Zero W(H)
Install go for armv6l
curl https://dl.google.com/go/go1.10.1.linux-armv6l.tar.gz | sudo tar xz -C /usr/local
Add the path to Go in your environment, such as /etc/profile
export PATH=$PATH:/usr/local/go/bin
Fetch this repository
If you have not already done so, create ~/go, which will host all of your Go code.
If you know what you are doing, use git to clone the library. Otherwise, use go get
go get github.com/lestrrat-go/epd
Install dependencies
This may take a while, because, well, you're running on a RP Zero
cd ~/go/src/github.com/lestrrat-go/epd
go get -u ./...
Run the tests
cd ~/go/src/github.com/lestrrat-go/epd
go test .

type EPD ¶
type EPD struct {
// contains filtered or unexported fields
}
func (*EPD) ClearFrameMemory ¶
func (*EPD) DisplayFrame ¶
func (e *EPD) DisplayFrame()
func (*EPD) Reinitialize ¶
func (e *EPD) Reinitialize()
func (*EPD) SendCommand ¶
func (*EPD) SendData ¶
SendData sends data through SPI. Arbitrary number of bytes can be passed to this method, and they will be each sent in succession
