Hi,
I am working on a project that requires feedback from 60 different relays. All the signal from the relay tells me is whether or not it switched so the output is 3.3V or 0V. Basic digital 1 or 0. The problem that I am having is that the microprocessor that I am using will not accept 60 different digital inputs. I'm not even sure if one such processor exists.
Is there a simple way to cut down the number of inputs? Like a giant PISO shift register? I would prefer the output to be something a few digital I/O pins could read or RS-485. RS-422 is also a possibility but I would prefer not to use it.
Thanks in advance.
