Hello All!
I made a tachometer and it works fine, but i want to use TIMER3 or 5 as a counter not the TIMER1, beacause TIMER1 already in use. The CCP setup function said "...In capture mode it will copy the timer 1 count value to CCP_x when the input pin event occurs..."
So I can only use the TIMER1 for capture??? Or is it possible with TIMER3?
In simulation both count, so i don't understand.
PIC: PIC18F48K22
My comp. ver.: 4.128
Thanks,
Stygian |

I solved it. It was a simulation bug.
But is someone in the future want the same I write it down here.
For a pic18F46k22 the code is the following:
| Code: |
#byte CCPTMRS0 = 0xF49
void main()
{
//User Code until CCPTMRSx
CCPTMRS0 = 0b00000001;
set_timer3(0);
setup_timer_3(T3_INTERNAL | T3_DIV_BY_1);
//User code from here...
}

ALWAYS tell us if this is REAL code in a REAL PIC or a stupid simulation !!!
Most of us do not want to waste our time trying to debug code that's 'running' on any simulator( none actually work correctly). |

I tell it in the beginning, but sorry if it was mis-understandable.
Btw. Simulators are crap. For e.g. Now it can't handle two isr.
If I and my 128x64 pixel glcd CS2 won't init...
