I want to measure 100 Hz to 6Khz frequency and display the value in LCD. I have completed the coding by using CCP - capture mode in PIC and the program executes well but the problem is, there is an error of about +/- 10Hz difference with my actual frequency. I want to reduce the error of about +/-2Hz. Im using 4Mhz external crystal. Is it possible to achieve? or do i have to increase my crystal?
