    Default Creating Bespoke output waveform

    Hi all

    I am new to this forum and need some help please!

    I need to create an output from my PIC which will be high for a defined time (+5V), it will stay high for a defined time but I then need the output to swing to -5V, I need the voltage to go negative.

    In other words I need to make an output swing from a positive voltage to a negative voltage, almost like a sine wave but with square wave characteristics.

    Not sure if i've been clear enough here but if anyone understands what i'm after please help!! I have uploaded a PNG file of the waveform i'm trying to create, hopefully that will help!

    Thanks,
    Adam
