Hey, i need to measure the time an input is high.. im using an external clock on pins RA6 and RA7.. i know how to use timer0 module but the maximum prescalar is 32.. can someone give me some hints..
and could you explain how the timer modules actually function? do they work directly from the clock signal? or does timer1 depend on timer0 and likewise? datasheets say something about them needing to be synchronized if you're using an external clock.. im quite lost :S please help
oh its alryt thanks anyways.. i figured out most of my questions from a book.. could you please tell me if theres a bit configuration where i can have timer0 as the source of timer 1 or 2? or any other way i can scale down the 4Mhz clock signal to the mili second level without software interference(using timers)
thanks i think i got it to work.. i figured that timer 1 is 16 bit so you can scale down the interrupt a lot. i used prescalar 8 and set the timer to 53036 so it generates interrupt every .1s.. and im using timer0 for some other purpose.. is there any restriction in using both the timers at the same time?
