Hello again, its been a while.
I'm having a bit of trouble daisy chaining some '164 shift registers.
I have the first hooked up fine, and it works as expected, but by hooking output 8 of register 1 to input a (also tried input b and input a&b and tying one high and low) and joining the clock and clear pins of the first to the second, it just doesn't work.
To test them, I've simply been shifting out(using wiringPi's shiftOut) 1 in a loop, incrementing by 1 each time, so its basically a binary counter.
Can someone please explain what the proper way to set these up is.
