    Default PIC Voltmeter

    Thanks Jerson,

    Heres the schematic of a PIC 16F876A with a LCD display showing 2 lines, able to output 2 voltages as i need.

    This looks like what i need, i cant get any responce form the site that has posted this schematic!

    Its a pleasure to get a responce to the question, thanks again Jerson.

    Cool

    Hi, Doable

    I think a look to the SAMPLES folder of your PbP CD will show you how to deal with the PIC A/D converter ... and display the result.

    search for "ADCin xxxxx.bas"

    The link you gave only allows ( with buying the '876 ) a 0 - 7v range ... by changing the input divider ratio.

    These examples are for '877 and '876 ... surprise !

    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    Alain gave you the direction, to your legal obtained CD. Are a legal owner?

    Thanks Alian for the information,

    I dont want to sound stupid but i have little experance in the PIC world, but have a great thurst to learn. Now with the system i am using are the code examples compatable. I have done enough to have learned that even between different PIC the basic code changes, I dont understand Microchip's reason for that.

    I will attemp to write to a PIC16F877A the sample code for the voltage meter, I am sure that i have more questions later on. Thanks again for helping with this!
