Can anyone please assist me on how to use the arduino to program an graphic microLCD by 4D Systems. The LCD has only 5 pins (TX RX GND VCC Rset) and it does not give any information on how to have a host/microcontoller drive the LCD.
Please assist!!
If it has TX and RX pins it is most likely serially controlled. But without more information on how to set up the serial comminication with the display and how to send commands to it, i'm afraid it's impossible to give you any advice.
But try to check here:
