Guys I need to load a 8 bit value to 74HC595 IC.Please see my code is ok?Its not working.
I use mikroC.The compilor generates such an asm code that I doubt.
It always set bit 7 of the mask register when I shift it right
Code:
void load_595(short num){
short mask;
for(mask=0b10000000;mask>0;mask=mask>>1){
if ((mask & num)>0) {
sdata=1;
clk_595();
}
else{
sdata=0;
clk_595();
}
}
latch_595:
slatch=1;
delay_us(1);
slatch=0;
}
void clk_595(){
sclock=1;
delay_us(1);
sclock=0;
}I use mikroC.The compilor generates such an asm code that I doubt.
It always set bit 7 of the mask register when I shift it right
Code:
//for(mask=0b10000000;mask>0;mask=mask>>1){
RRF load_595_mask_L0+0, 1
BCF load_595_mask_L0+0, 7
BTFSC load_595_mask_L0+0, 6
BSF load_595_mask_L0+0, 7
