How does pic16f877a work on digital frequency meter?
PIC16F8877A microcontroller externnal interrupt at rising edge and timer are used to measure time period of square wave. algorithm is developed to convert time period into frequency. 16 * 2 LCD is used to display measured frequency digitally.
What do I need for a PIC frequency counter?
All you need is a PIC microcontroller (or any microcontroller that has a high speed timer input module) and a 2 line LCD display (the standard HD44780 one is the one used here). This PIC frequency counter project uses an LCD to display the frequency and PIC timer 1 to measure the input signal and Timer0 to measure the timing period.
Do you need a microcontroller for a frequency counter?
A frequency counter is a useful addition to an engineer’s toolbox and you can create the design described on this page for free. All you need is a PIC microcontroller (or any microcontroller that has a high speed timer input module) and a 2 line LCD display (the standard HD44780 one is the one used here).
What is the TCY of a pic16f877a MCU?
With a 20MHz Fosc from a crystal in HS mode the PIC16F877A will have a Tcy of 200ns. As you can see, if you are using synchronous mode and the prescaler, with a standard part (i.e. not LF), the T1CKI minimum high and low times are 15ns each.
