I don't know what "recycling" is.Can be 0000 to o111 or 0001 to 1000, but no recycling.

I need some help in getting my cd4029 counter to do what I want.
I'd like it to do a continuous count both forward and backward using ONLY 8 counts.
Can be 0000 to o111 or 0001 to 1000, but no recycling.
Mike, counting 1 through 8 is just as good as 0 through 7. (from post #1)
The part counts 0 through 7 with out adding logic. Just, do not use the highest bit.
You will have to add an external flip-flop which is used to change the direction of counting. That flip-flop is set to count up and cleared to count down. You will need to detect the two "turn-around" states (0000 and 0111 or 0001 and 1000) to alternatively set and clear the "direction" flip flop.
