== Hardware connection ==
|
||
EPD => Raspberry Pi
|
||
* VCC -> 3.3
|
||
* GND -> GND
|
||
* DIN -> MOSI
|
||
* CLK -> SCLK
|
||
* CS -> 24 (Physical, BCM: CE0, 8)
|
||
* D/C -> 22 (Physical, BCM: 25)
|
||
* RES -> 11 (Physical, BCM: 17)
|
||
* BUSY -> 18 (Physical, BCM: 24)
|
||
|
||
== How to use ==
|
||
1, open spidev.
|
||
spi is enabled in config.txt:
|
||
dtparam=spi=on
|
||
or in shell:
|
||
sudo raspi-config
|
||
- 5 Interfacing Options Configure connections to peripherals
|
||
- 5 Interfacing Options Configure connections to peripherals
|
||
|
||
2, install the C libraries：
|
||
sudo apt-get install git
|
||
sudo git clone git://git.drogon.net/wiringPi
|
||
cd wiringPi
|
||
sudo ./build
|
||
|
||
3, change the current directory to where the Makefile and demo files located.
|
||
|
||
4, compile the file with:
|
||
make
|
||
# If you need to see the debug information, clear the execution:
|
||
make DEBUG=-DDEBUG
|
||
|
||
5, run the demo with:
|
||
sudo ./epd
|
||
