hi all
i am very much new to embedded systems ok so i really need help..i am using an keil board mcb 2140 with arm7 lpc2148. i am trying to interface a lcd and a keypad..i hav emade all the hardware connection required and in the display it shows the square matrix as well, now wen i send some data or any command to the lcd it has no effect..coud u please tel me wat would be the problem
We also use LCDs and mostly this is because of an incorrect initialisation sequence of the LCD chips. Timing is very important here. You must do the init as described by the manufacturer.
could u tell me wat will be the sequence and the delay plz
Post all your code here and we will have a look for it.
