we are having keil MCB2140 kit.we are trying to interface LCD to this kit which has LPC2148 as the microcontroller.The LCD'S supply votage is 5v.we have given it through an external supply. The boards supply voltage is 3.3 volts. We are not getting the result. The query we are having is if we send commands from the board to LCD in terms of high-low voltages through ports,does the LCD accept this high voltage of 3.3v.
