    Hi all, I have to reverse a byte with a PIC16F877A in Assmbly code.
    I tried to implement a function by shifting to left te W register, tried with a function with 256 retlw but it also did not work due to stack overflow..

    Do you know or do you have an algorithm for this purpose?
    Thank you for your help

    It would be nice to have some idea of which programming language you use. And what you have done so far.

    I am sorry. I understand your correctly answer. I have edited the post later.. I work with Assembly Language in MPLAB.
    Later I will post my wrong code, I can't post it now due to it's on Windows in VBox, just turned it off and I have to turn off the laptop. :(

    How about:
    clrf temp
    bftsc source, 0
    bsf temp, 7
    bftsc source, 1
    bsf temp, 6
    etc
