As think I understand it, I need to latch low, make two 8 bit shiftout() calls then latch high again, to accomplish sending 16bits of data to the a6279 chip. Is this a wrong interpretation?
I could not detect that any voltage was being supplied to the led pins of the driver.
I've also included a commented out for loop, that is supposed to be used used to cycle through 8 bits.
which is 16 bits? as I understood the shiftout() function, it only handles 8 bits,
try sending 0x0000.
The shiftout() toggles the clockpin at the end of 8bits.
This isn't any sort of product, just one off led lighting project
I'm fairly certain I am wired correctly, but re-checking again probably couldn't hurt.
I wonder if I should just get two 74hc164 8 bit shift registers like all the other led projects on the web. ...
