I was planning to use a 18F4550 to collect data from 24 bit counter/shiftregister and also enter data from keypad. I thought I could also use the additional I/O ports to drive 7 segment displays. However I want to provide the shift clock, counter gate and reset from the 4550. The counter gate is 1 second, so when all this is in a main program loop, I can't see how i can loop the display at the same time fast enough to refresh the display. I am not an experienced programmer and this is basically my first time trying to do something like this, so hopefully someone can give me some advice. I was thinking I could use a dedicated PIC just for the display, and go with a lesser processor than the 4550 for the other functions.
