# * | 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 = epd2in13.EPD()
|
|
# epd.init(epd.lut_full_update)
|
|
# image = Image.new('1', (epd2in13.EPD_WIDTH, epd2in13.EPD_HEIGHT), 255)
|
|
# ...
|
|
# drawing ......
|
|
# ...
|
|
# epd.display(getbuffer(image))
