I use STON display module. But I cannot communicate with 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 dipslay using SSCOM with PC, there is no response from display. In my proejct I have 1.JPG file. I don't know what went wrong.
I suppose if you were to explain to use whatever on this planet a "STON display module" actually is, with the essential web-link to the site detailing it, we just might be in a position to assist.
