Microcontroller › 8051 › LCD interfacing
Hello friends,
I have interfaced 16×2 lcd with at89s52 microcotroller. i also define it in programing but 2nd line of LCD is not glowing wats the reason?
Please tell me about this problem..
I don’t know what exactly you mean by “GLOWING”, if it’s the backlight, Connect 15th Pin to Vcc and 16th to GND.
If you are referring it to the Data display, try Sending “0xC0” when you initialize your LCD and then send some data to get display on the 2nd Row. Hopefully it’ll work.
Regards,
