#113699 - To turn OFF LCD backlight |
Hi,
I gone through the forum search regarding LCD backlight.It was informative,but the discussions were based on the power consumption. Please tell me how to turn OFF the LCD backlight when the keypad is not used?What are the changes to be done in the control words used in the program? The initialisation routine for 16x2 Character LCD is as follows: void lcd_init(void) { write(0x38,0); //set 8-bit mode write(0x06,0); //screen on write(0x0E,0); //shift right write(0x01,0); //clear display } I've given +5V to Anode and Gnd to Cathode pin. Also tell me whether any additional connections are to be done in the LCD backlight Anode and Cathode pins. awaiting for your reply, Veenadevi. |
