Decade Counter with 2 x 7 Digit displays, need help / advise on a couple of mods ;-)
Hi every one and thanks for looking at my post ;-)
ive got a Decade counter circuit which is ok ive added a start / stop and a reset button to the diagaram - but what i want to be able to do is the following
1) Add a 2nd set of 7 digit display's which i have done under livewire and they power up but i want them to show the high count ie
if the main ones lets say they are the top digits gets to 22 then the bottom ones will show 22 now when its reset the top ones will reset (already have this on the circuit now) and the bottom ones stay on 22 then
next time its started if the top ones dont get to 22 then the bottom ones will stay showing 22 and if it gets to over 22 then the bottom ones will then register the high count and stay on that until its reached again.
if that all makes sence? - as i want to be able to make 1 pcb which i can populate either with or without the 2nd set of 7 digit displays as i have some uses where i only want a counter not a "high count memory"
hope ive explained ok for everyone to understand lol
any help would be much apreaceated!
thanks in advance
Neil
