    Default Re: Control a Radio PLL with a PIC

    That's funny. I just ordered 2 pic18f4431 s on Thursday for this specific purpose. I found even using asm interrupts the 16f690 too slow to track the encoder without losing steps, (either that or it was switch bounce). So I figure to use a PIC with QEI Hardware inputs and a 40mhz clock. Failing that I will try using flip flops to buffer the inputs. In any event there is plenty to learn.
    Now off to Costco for a box of Corn Nuts, and 3 pounds of coffee . . .
    Edit:
    I also want to display the count from 0 to 255 in decimal on a 3 digit 7 segment LED display.
    PIC is an 18F6680.
    Or you can use a lookup table and display channels or frequency.
