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
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.
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
with the posted wire-setup it makes no difference, you can send whatever you like, it just won't work ... :-)
Shouldn't it be ser.write('t2.txt="Hello"\xFF\xFF\xFF') ?
it can't work with your wireing ...
- Rx <-> Rx ???
- Tx <-> Tx ???
something Send out must be Received ...
