hello
I use the STON display module. from: https://www.stoneitech.com/product/by-application/industrial-type/stvi070wt-01.html But I cannot communicate with the module using UART. I tried different serial port applications like SSCOM, RealTERM, SerialPlot but nothing changed. When I sent this command: 0xA5 0x5A 0x04 0x80 0x03 0x00 0x01 to display using SSCOM with PC, there is no response from display. In my project, I have a 1.JPG file. I don't know what went wrong.
Can someone tell me !!!

What are the voltage levels and sense of the UART signals from the sending device to the display module.?
