Help in 7-segment display ?

[Brian Griffin]

On times multiplexing a display (especially more than 4-5 digits) can take up a lot of the microcontroller's time. Some preferred using a seperate multiplexed seven-segment decoder chip and only the data is passed to that chip from the microcontroller.

On the other hand, an FPGA could perform all that task in a parallel manner without stalling the system, but it is a little bit overkill for a small counter.

I have made parallel 8 seven segment. Use timer interrupt to do 1/8 blinking, see here.

Oh.... Ober, really uses 4511? So you share the output pins from PIC for both encoder and uses the latch pin to filter the output pin. Great idea!
