I need some ideas/feedback on how to solve a problem where I'm going to share four outputs from
an Arduino to different independent 595 circuits using two extra address lines.
Each unit will have a 2x DIP switch that can select the address.
I have searched for possible solutions, but have not found anything.
Below is a draft diagram of how I think this can be solved. I have assumed that the SER(ial input)
pin on each independent 595 circuit can be shared with no extra logic. It is the SRCLK, RCLK and
^SRCLR that need to be handled by the extra logic.
Only the important connections are shown.
Some comments/feedback on this would be nice.
