# * | File : epd2in13d.py
|
||||
# * | Author : Waveshare team
|
||||
# * | Function : Electronic paper driver
|
||||
# * | Info :
|
||||
# *----------------
|
||||
# * | This version: V3.0
|
||||
# * | Date : 2018-11-01
|
||||
# * | Info : python2 demo
|
||||
# * 1.Remove:
|
||||
# digital_write(self, pin, value)
|
||||
# digital_read(self, pin)
|
||||
# delay_ms(self, delaytime)
|
||||
# set_lut(self, lut)
|
||||
# self.lut = self.lut_full_update
|
||||
# * 2.Change:
|
||||
# display_frame -> TurnOnDisplay
|
||||
# set_memory_area -> SetWindow
|
||||
# set_memory_pointer -> SetCursor
|
||||
# * 3.How to use
|
||||
# epd = epd1in54.EPD()
|
||||
# epd.init(epd.lut_full_update)
|
||||
# image = Image.new('1', (epd1in54.EPD_WIDTH, epd1in54.EPD_HEIGHT), 255)
|
||||
# ...
|
||||
# drawing ......
|

* 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 Python libraries.
|
||||
sudo apt-get install python-pip
|
||||
sudo pip install RPi.GPIO
|
||||
sudo pip install spidev
|
||||
sudo apt-get install ttf-wqy-zenhei ttf-wqy-microhei
|
||||
|
||||
3, change the current directory to where the demo files located.
|
||||
|
||||
4, run the demo with:
|
||||
sudo python main.py
|
||||
# if use python3:
|
||||
sudo python3 main.py
