    This would likely fare better in another section of the forums other than "Off Topic"?

    Do you want code for PIC16F877A ? Do you have a circuit ? If not, then can I design the circuit ? What is the max battery voltage ?

    Draw the circuit using Proteus if you have or draw it on paper and scan it and post the circuit.

    Do you want to display floating point values or just integer values ? Floating point values will be better.

    Just provide circuit in whatever format you can or mention the connections.

    This image will not help me.

    Just mention connections like

    7 Segment Display
    A -> RD0
    B -> RD1
    C -> RD2
    D -> RD3
    ...
    DP -> RD7

    You want to retain the same pin connections for PIC16F877A ?

    PIC16F877A doesn't have Internal Oscillator. You have to use an External Crystal Oscillator. Can you use 4 MHz Crystal ?
