Sorry if this thread is a repeat. I do remember seeing something of the sort, either on this forum, or another, but...
I am busy using a PIC 12F675 (8 Pin DIP). The problem is that I require more I/O than is available on the Chip. I recall briefly seeing an article/post on either this or another forum, where an analog input channel was used to create two or more digital signals form it, something like the comparator function available in most PIC's but with multiple set-points if you will.
I don't want to use the comparator way, because that uses two pins.
I have "tried" to search this forum, but as most of us know, this is not Google, and the use of key word such as "AND" etc. does not yield the desired results. (More than 500 returns, and none are relevant)
This is not homework, or some post graduate project. Simply a hobbyist wanting to learn something new.
Thank you.
