    frequency meter pic led display

    lc meter 2051 that means you have to use PB0...PB7 from PIC16C622 as PB0...PB7 for PIC16F877 and so and so... only change the pin numbers according to MICROCHIP datasheets for each new micro. It's clear for me !

    How to control this circuit using a micro?

    I'd like to use this circuit in my new project to get different voltages from +5V (for example from +5 to +24V). I know that this can work but I cannot control it. All comments and suggestions are wellcome!
