Can’t write data from Orange Pi to Nextion
I try to communicate nextion display with Orange pi lite, I can receive data from the display, but can’t send it using WiringSerial library or serial library for python.if I use common file write() in C program, and try to catch an error by errno.h, it gives me:
value of errno 14
error printed by errno: bad address.
Code for python looks like:
import time
import serial
ser= serial.Serial(‘/dev/ttyS3’,9600)
EndCom = b’xffxffxff’
while True:
temp=“page 0”
time.sleep(0.5)
temp=temp.encode(‘ascii’)
ser.write( temp + EndCom) We hope you enjoy playing our free 2048 game, and best of luck on your way to producing a tile with a value of...2048!
