I need a multiple event counter build around a pic16F877, the first and second counter must have 3 digits, counters 3,4,5,6,7 must have 2 digits. pic outputs must be in BCD in order to decode data to digits using a CD4543 per counter, inputs debounced and if posible an LDR to control brigthness. PIC16f877 it´s not a must but preferable.

Experienced electronics engineer, done many projects with PIC devices, including one 7-segment LED counter project. Please see private message. Thank you.
I do not believe the BCD to 7-segment decoders are needed if there are no other requirements for the controller. I dont have an '877 handy, and would need a few days to acquire one.
