Hello ,
I am sridharan,i am using BF532 processor.i am interfacing BF532 with character LCD.
for tha t i am using shift register 74HC595.my interface is like,
SPI dataline - pin no 14(SER)with pullup resistor
one pf line - pin no(RCK)latch
SPI clk - pin no 11(sclk)
pinno 1 to 7 & 15 data lines to lcd
here i am getting datas in the lcd.But frequently i am getting some garbage values.
& entire display in lcd is shifting towards right side.i am thinking command & datas are is not going properly to the lcd.
my procedure is
putting data in SER of 74hc595 ,
delay
latch low to high with some delay& again low
how to solve this problem.
thanks
