varitronix lcd
Hi,
i am interfacing the VARITRONIX 20X4 lcd the part number is MDLS20464-LV-LED04 with 8051 based controller
i previously interfaced HD44780 20x4LCD no problem but when i am using same program with this LCD it is not working
i think program is working fine there is any problem in Contrast voltage at pin 3
i don't know why the data is not displaying on it i tried several time and i gave different voltages Negative and positive on Contrast pin but no use...
kindly tell me
