| Hi-
I want to pass ad12temp between main and an interrupt. When I interrupt, the value passed is incorrect. I know this because the wrong condition is returned. I thought it was because I am compari ... |

| Thanks for the link and suggestions PCM.
I have read all functions. I thought I would not need the driver since all I am doing is reading. The data sheet seems fairly straighforward on the steps t ... |

| Hi- I started with the following code- it is a comparator interrupt on PortA . Pins A0, A1 wired together to a pushbutton switch. It works reliably.
