    Angry HOW do you initialize PortC to normal I/O??

    Hi folks,
    I'm using a PIC16F917 with PicBasic Pro for the first time (but my problem occurs w/ a 877 too), and I just want to make PortC behave like a normal output port! As it powers up, apparently the LCD peripherals come up configured which disallow me writing to PortC.0, C.1 & c.2. I have set TRISC to %00000000 to no avail.

    Please help!
    Thanks much

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    I tried that, and PBP gave me an error. Since LCDCON lives at 107h, in desperation, I added "LCDCON equ 107h" to the M16F91X.INC file, and then tried it again:

    LCDCON = 0

    again, and it worked!

    Thanks mucho.
