Yeah - RCTIME is a bit inadequate for that, there's not enough span at the lower end. I think min is a few KΩ. Besides, relatively inefficient too, tying up a complex protocol for something so simple.

I could easily see throwing a few push buttons, each with their own resistor, on the same pin, with a parallel cap, and using RCTIME to figure out which switch was pressed.

That is a very good idea!Originally Posted by skimask
