I have a question aboutl Shifting.
As I have read you can use 3 digital pins (clock, data,latch) of an arduino to control an external bit shifter for adding more digital inputs or outputs
Also I read that you can control more than one external bit shifter with these pins.
But from examples I saw that always was for the same purpose.. Let's say that you had bitshifter for input and then Adding another input bitshifter also.
My question is :
Can you add both input and output bit shifter at the same time?
Can you use the same 3 pins for both different functions (input /output)
Thanks in advance
Ps : I wasn't sure if that was the right topic to post or to project guidance
