Hey All,
Just a quick thank you in advance!
Ok, so I have a circuit as shown - a 555 timer set up with a period of 0.5 seconds. Now, this is driving an 8 bit counter, which I am using to trigger other things.
So, I am using Bit 4, which should go high @ 8 seconds, and bit 5, which should go high @ 16 seconds.
The problem I am having is that bit 5 is actually going high at about 27 seconds as shown in the output waveform.
Now I know the 555 isnt outputting a perfect square wave, but nearly a square wave. Is this the reason why? Just cant get my head around it!
Cheers,
PP
