I bought the NX3224T028 version and I like it a lot. Congratulations on the design of the device. (It would be good a version of Editor for Linux)
Currently I'm trying to communicate with the screen in python. I can receive boton event with the command serial read, but I can't write or the screen does not respond.
So my question would be to know if I could try with a serial port program like "moserial" to try if I don't have a problem with my LCD?
I try to send this command for example: sendmeÿÿÿ
Or some other test the verify the communication. (without arduino)
USB/TTL(serial - CP210x UART Bridge) <-> LCD Nextion
5V <-> 5V
Rx <-> Rx
Tx <-> Tx
GND <-> GND
Python program to test write:
ser = serial.Serial ('/dev/ttyUSB0')
ser.baudrate = 9600
Thank you very much
it can't work with your wireing ...
- Rx <-> Rx ???
- Tx <-> Tx ???
something Send out must be Received ...
Shouldn't it be ser.write('t2.txt="Hello"\xFF\xFF\xFF') ?
with the posted wire-setup it makes no difference, you can send whatever you like, it just won't work ... :-)
In that case I'd check my wiring and USB to TTL adapter first by trying to do manual serial communication between the IDE and the display
TX -> RX
RX -> TX
If for any reason the silk is wrong on device, I would toss the incorrect one.
- but could also be some sort of code configuration error
In any case, to frig with a one off where silk maybe wrong is one thing
- if this is a multiple unit scenario ... yeah, I don't know, I'd figure which is wrong and toss it.
