It works!
So goood!!!
my "main" :
Code: Select all
import machine

dc = pyb.Pin('Y5')
rst = pyb.Pin('Y4')

e = epaper2in9.EPD(spi, cs, dc, rst, busy)
e.init()

loop=asyncio.get_event_loop()
loop.run_until_complete(display_values())
#asyncio.run(display_values())

loop.run_forever()I'm so grateful for your help...
THANKS.
All the best.
