I am tearing my hair out trying to get through this and have just about admitted defeat. I have enclosed a small program for a decremental counter. I am using the analog blocks to try and get a value from the counter block as a reference. At the moment I can count down to zero from any figure I input using F1 and F2 then the counter resets and pauses before starting again after a hard reset. The problem is I need to input very high numbers, as high as 31000. Does anyone know of an easy way to get a referenced value into the counter from either BCD thumb wheels or even a potentiometer. I will be forever in your debt if you can help me in any way.
