    frequency meter schematic

    i did lots of work on frequency meter from silicon chip , did not succeed.

    i am looking for another small but good working frequency meter using PIC16F84A
    and LCD.

    last time i saw the ckt of such kind with 0.8vpp sensitivity , i am not exacty remember
    web add of it but everything is given on that web page , and the pcb size of that project is similer to 16x2 LCD .

    sorry , i tried but not succeed .

    thank you
