Has anyone succeed to play with this ePaper screen

on the orange pi zero 2W ?

I have download the required files, and install all required pip package.
I have also set the proper permission to gpio/spi/i2c, following this

but i still get

  1. [Errno22] Invalid argument
Copy code
which, as far as I understand, seems to be related to this kind of error
  1. orangepi@orangepizero2w ~ echo 3 > /sys/class/gpio/export
  2. write: Invalid argument</div>
Copy code
as a MWE i tried

  1. <div>import OPi.GPIO as GPIO
  2. import time
  3. #We need this
  4. from os import geteuid

  5. # Pin Definitions:
  6. ledPin = 4

  7. # Pin Setup:
  8. GPIO.setmode(GPIO.BCM)
  9. GPIO.setup(ledPin, GPIO.OUT) # LED pin set as output
  10. #If we're not root, sleep 100ms in order for udev to set
  11. #the permissions on the exported GPIO right
  12. if(geteuid() > 0):
  13.         time.sleep(0.1)

  14. print("Here we go! Press CTRL+C to exit")
  15. try:
  16.         while 1:
  17.                 GPIO.output(ledPin, GPIO.HIGH)
  18.                 time.sleep(0.5)
  19.                 GPIO.output(ledPin, GPIO.LOW)
  20.                 time.sleep(0.5)
  21. except KeyboardInterrupt: # If CTRL+C is pressed, exit cleanly:
  22.         GPIO.cleanup() # cleanup all GPIO</div>
Copy code

but i get
  1. OSError: [Errno 22] Invalid argument

  2. During handling of the above exception, another exception occurred:

  3. Traceback (most recent call last):
  4.   File "/tmp/", line 11, in <module>
  5.     GPIO.setup(ledPin, GPIO.OUT) # LED pin set as output
  6.     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  7.   File "/home/orangepi/code/venv/lib/python3.11/site-packages/OPi/", line 480, in setup
  8.     raise e                           
  9.   File "/home/orangepi/code/venv/lib/python3.11/site-packages/OPi/", line 472, in setup
  10.     sysfs.export(pin)
  11.   File "/home/orangepi/code/venv/lib/python3.11/site-packages/OPi/", line 37, in export
  12.     with open(path, "w") as fp:
  13. OSError: [Errno 22] Invalid argument
Copy code
many thanks!
