Hi to all. I am new to using PIC's and am a but stuck. I want to count down from 8999 (d) to zero in 60ms , and then repeat. This works out as counting at about 150khz. Am using a pic 16c84 at 4Mhz. I wrote a routine to do this , but as I am a beginner my code was not all that good:0) , and it took to many instruction cycles and was hence to slow.It needs to count at 1 count per 6.6us about.I can use TMR0 and I can use an external clock source if need be. Am I going to have problems because the PIC is to slow maybe? Any help would be appreciated. Cheers all Rob
