I managed to make it count down from 5 to 0 and then looping back to 5.
I have forgotten about using PL, D0 and, D2 to make the counter skip to five after reaching zero.
Issue resolved.
I remade the circuit to make it more compact and hopefully easier to read.
I used a DPDT switch to control whether the circuit would count up or down while making sure the unused input be set at logic '1'.
It counts from 0 - 5 then loops back to 0 when it is counting up.
But while it does...
Yes, I understand that now and did just that in the previous post I made.
I am still working on the circuit and still, even when I set UP at logic '1', the circuit would still not count down properly and would get stuck at 0.
Could you please help me with this? I have been on this project for...
I reckon you mean I should leave the unused input at "1"?
I modified the circuit so that when I want it to count up, pin 4 is at logic "1", and vise versa.
It counts up as expected. However, it does not count down and is still stuck at zero.
Hello, I am working on a digital game clock using down counters from 74192 and 7448 ICs.
I tried this following configuration and, when counting up, it counts from 0 to 5.
But when counting down, it is only stuck at 0. I've tried setting the counter from 5 before letting it count down, but...
