i want send the serial bit through pin RA3 to serial LCD
my 1st frame will be as this 00010 0001
but LCD also require clock pulse and this pulse should be synchronize with serial data i want this pulse generate when pic start RUNing i hope u can help me in this when i finish this i will put complete one there
i am using nokia LCD 3310 and it is has this pin
SCLK Input for the clock signal: 0.0 to 4.0 Mbits/s.
D/C LOW command mode or high DATA mode
SEC The enable pin allows data to be clocked in. The signal is
active LOW
RES RESET
SDIN 8 bit serial DATA in
i did every thing just remaining that there should be clock pulse for LCD
i want RA4 to generat clock pulse 4 LCD (am using 16F84)
some one told that i can use 16F877 which has bulid in clock pulse out which is pin RC3
