I am hoping for a little guidance , I may be taking on a project a little beyond that of a beginner to microcontrolers but let me outline what I am trying to do.
I have a CB radio I am modifying for 10 meter ham use. what I want to do is remove the 40 position channel selector and program the PLL directly off a PIC set up to run as a binary counter , that seems to be the easy part , where it gets complicated is I want to interpret the binary count being delivered to the PLL and display the coresponding frequency on a display , either LCD or LED , the PLL is programed via 8 bit binary and I need the count to run n:101 - n:255 (1100101 -111111 ) and reset , be selectable as a down counter or up and be able to halt the count when the desired frequncy is reached.
I was originaly going to do this with a bank of 74192's on the pll end a a bank of 74192's and 74247's drining a 7 segment display but I think the microprocessor woud do the job better
any help would be greatly appreciated , I am eager to learn and not unfamiliar with electronic theory , just new to PICs
