![]() The basic idea comes from the AN592 Microchip application note: "Frequency counter using PIC16C5x" where you may find a simple software wich implements a frequency counter using a PIC microcontroller.32 MHz max frequency from internal PLLed oscillator. INCREMENT VALUE IN NCO MODULE Therefore, a better frequency resolution over a wide frequency range can be obtained using the NCO for Again, the range of the counter can be extended by the use of the prescaler. First I tuned my guitar with a electronic tuner. PicKit2 is a programmer designed by Microchip to program its pic microcontrollers.The maximum frequency: Up to 120MHz is the frequency that those beauties can reach. Each machine cycle (or instruction cycle) for a PIC microcontroller consists of four clock cycles, which are named as Q1, Q2, Q3, and Q4. Microchip pic frequency counter In other words, three frequency checks are done every second.
