LED Message Board!!!
i would suggest u use C or picbasic pro for ur project... so u can left those redundant stuff to b done by the compiler n u can concentrate on ur algorithm...
mostly this type of chift register is quite simple to use... mostly is clk, strobe, enable, data...
as it name imply, the clk is the shifting clk..... strobe is like latch when u assert this strobe, data will capture... the enable is to let u ON or OFF the output pin... data is those pin connect to the LEDs which to b ON or OFF...
wth PICBasic Pro, there is the "shiftout" instruction u can use wth this type of shift register... this instruction is built for for this type of shift register.. very convenient
if u are using CCS C, then shift_left() or shift_right() is almost the same as the "shiftout" but more things to control... C let u hav more control on ur program... in my humble opinion..
try it first then mayb i can help..
