Im designing a project and im a little stumped on one feature i want to implement.
how can i take a percentage of 2 counter ICs? or even more elaborated, cascaded counters.
im using 74LS192 BCD counters and 74LS85 i believe is the binary comparator.
so how can i take counter#1 and check if it is 75% or higher out of counter#2?
and another problem i had was that counter#2 would always be 3 or 4 counts or clocks ahead of counter#1 because the way my circuit was designed.
i did think of taking NOR/AND gates to give a reset to counter#2 by checking if the inputs are 0000,0000,0011 (3 digit bcd) but just wondering if there was an easier way without all those zeros(so it doesnt reset on 13,103, etc..)
also some side questions, is there a chip that combines BCD counter with 7447 display driver into one chip?
thanks
