PostPosted: Sun Mar 20, 2011 9:10 am     Reply with quote

I'm using Timer0 & Timer1 as counter in PIC18F2550, now I wanna ask can I use Timer3 as a counter as well ??

In datasheet its written as "T13Ckl" on a pin.

I suspect the question is: "I want three independent counters". The answer is "no", because Timer1 and Timer3 use the same pin T13CKI for their external input.

You'll have no choice but to use one of the external interrupt pins and do the counting yourself, either the interrupt-on-change pins (B4-B7) or one of the level-triggered pins B0-B2.
