    Hello Guys,

    I'm doing a project with the 16f877a but I'm having problems with the proteus simulation. I tooke a model project with 1 analogic port and I want to change for 4 analogic ports, but this model project is'nt running in proteus correctly.
    I'm having a problem with the proteusVsLCD.
    do you use the LM016L LCD without problems? Is The frequency for it 250kHz?

    Thanks

    You will have to configure the "adcon" registers to select the number of input that you wish to be analog inputs (check this on the data sheets).Your LCD should work fine.Daniel

    Lightingman,

    My register Adcon0 and Adcon 1 are configured. I suspectthat the problem is in the proteus, but it is a model project that, I can't to do it in proteus.
    The LCD works but is'nt updating data.

    Thanks for your attention.
