Not working with arduino uno #2

Hi @miandehe ,

I can't get the library to work with an arduino. Is there some special wiring? I wired the circuit as shown in the datasheet.

@hirani89 did you ever get it to work?

Figured out my issue. I had to add two more nop commands to the writeZero() method as the timing was off. This was for an AtMega328P. I would imagine this might be slightly different for different microcontrollers.

void TLC5973::writeZero() {
    pulse();
    NOP;
    NOP;
    NOP;
    NOP;
}

I guess this depends on the compiler. I had to double the amount of NOPs to for both writeZero and writeNone

void TLC5973::writeNone(){
    NOP;
    NOP;
    NOP;
    NOP;
    NOP;
    NOP;
    NOP;
    NOP;
}
