Darrel,

My program is working fine with the 16F727 and the 16F1939 as it is. But, I think it will run a lot smoother if I use the DT interrupts .

The amount of time that the chip takes between ISRs is very critical for the CSM (Capacitive Sensing Module) to work properly. So, please excuse my next dumb question . Can I say that I have a much better control of the interrupt intervals using DT interrupts than using ON INTERRUPT? And why?
