    Re: PIC18F1330 PLL problem

    Tumbleweed nailed it. Changing from "Internal Oscillator Block" to "Primary Oscillator" got it running at 32Mhz. Microchip seems to have gone out of their way to make this confusing.

    Re: PIC18F1330 PLL problem

    Thanks, George. Testing the IOFS bit didn't help, and I'm not sure how to check FOSC3:FOSC0. The oscillator type is being set by Fuse Configurator.

    Re: PIC18F1330 PLL problem

    Thanks, Charlie. Unfortunately that didn't do it.

    I haven't needed to write any code in several months, so it's likely I'm making a bonehead mistake somewhere. I've used the PLL many times on...

    PIC18F1330 PLL problem

    I'm just starting out on a new project that uses a PIC18F1330. I haven't used this specific chip before, so I began by trying to blink an LED just to make sure I've got things working right. My LED...

    Strange- I'm not seeing any of these problems. I usually use Opera, but I just tried Chrome, Firefox, and IE, with no problems on any of them. Could it be that problem has been resolved?

    I can't seem to get anything out of the SPI Master.

    I've got the MSSP set up like this:

    Hi Charlie-
    It looks like OSCCON is missing from your code. Try OSCCON = %01110010. Also, I'm not seeing OSCFRQ as being a valid SFR.

    For calibration purposes, you could start with a stable crystal oscillator, maybe 10 to 50 Mhz, and feed the output into a snap diode. This can generate evenly-spaced harmonics (a "comb...

    Re: Slightly surprised by 18F26K22

    ....but the 4.7K pulldown is only in the circuit while the Pickit is connected. As soon as you're done programming and unplug the Pickit, it's not an issue.

    Re: Slightly surprised by 18F26K22

    Yes-exactly. You can probably go higher on the resistor to reduce the load on the programmer. Maybe even as much as 10K. Sounds like some experimentation is called for.
