      Display STWI070WT-41. I’m trying to connect to Arduino. It is possible to send data to the display, but the panel does not send anything to the Arduino. Connected like this: HMI | Arduino RXP DI <-> TX TXP DO <-> RX GND <-> GND TTL welding pad connected. No TTL signal on TXP DO. Tell me, please, what I’m doing wrong.

      Maybe you need to change the screen to a TTL signal, you can refer to the manual, or take a picture of the back of the screen to show me

      I switched the screen to TTL signal at the very beginning, but it does not send me data.

      Please remove the three resistors marked by the arrows in the figure.
