Hi all,
I've been trying the ShiftIn tutorial, but by switch presses are not being registered at all. When monitoring the serial input, I just get 0 returned every time.
I am using the following chip instead of the CD4021B:

I'm guessing that the problem could be that this chip has synchronous parallel output instead of asynchronous. It that is the issue, would it still be possible to use this chip with different code? Or should I order some new chips?
Thanks!
