Hello guys.
I have purchased a STVI056WT screen, here is the interface and screen properties.

On the screen, when i click on the first button (KA6) i receive 2D A9 BE EA 29 7F DD 00

Here is the configurated port and received data :

I know that my USB-RS23 works fine (i’m using it to flash the arduino connected to the screen).

Any idea ? Where am i wrong ?

Cheers

Resolved :

Logic is inverted 0v mean 1 logic and 3.3 means 0 …

i had to use an arduino to inverted the logic level :

the last param (true) mean logic is inverted.

Serial2.begin(115200, SERIAL_8N1, RXD2, TXD2,true);

It took me a few days to figure this out, but thank you ZAMBINOU – I am working now thanks to Arduino INVERTED flag.

 

I am now off to try Pico running CircuitPython, wish me luck.
