RS-232 - LCD Dwin communication
#1
Photo 
Hello everyone ! I have bought some KC868 - A6 modules, a Dwin DMG10600T070 display, which has a configurable RS232 or TTL serial interface port. The screen is powered at 12V and GND is linked to the power and RX - TX communication pins (DB9, pin 2 TX2, pin 3 RX2, pin 5 gnd). When I use the screen simulator and connect the KC868-A6 module to the PC's USB port, the program works perfectly and the communication executes the programmed commands. My query now is how can I program the arduino based KC868-A6 module for RS232 serial communication with the display with the RS232 port that the module has!.

you can connect your display to KC868-A6 by RS232 port directly.
install arduino IDE, use Serial.print command to work with your display. this is easy, you can search on Google.

Okay ! I think I rushed to post! The problem was that I had the connection between the screen and the KC868 [TX - TX] [RX - RX] module, so I had to cross the signals like this: [TX-RX] [RX-TX], sorry, it's solved!
