Forum: General CCS C Discussion Posted: Thu Jun 10, 2010 8:46 am Subject: PIC18F2620 CCP Double Edge Triggering |
| My frequency input is in the range of 3-50Hz. It was a bit unstable, so I passed it through a schmit trigger to square off the signal. This really cleaned it up, but I was still getting a trigger on ... | |
