im looking for some way to convert a 16bit output into a display with 5 individual 7seg displays. its for a project i have going with my OOPic micro controller. a discrete ic would be nice, even though it would mean a 50+ pin chip, it doesnt matter in this case. i cant use a software solution due to the lack of IO lines and processing speed. ANY hardware solution would be greatly appreciated! thanks!

 

Use external BCD counters. Send a counting clock to them from the PIC, while decrementing the 16 bit value down to zero. You'll need two pins, one for a clear signal, and the other for the count.
