Hi Guys
Struggling to see why my circuit isnt working as i had designed. Can someone advise as to what might be the problem.
Basically i am using 2 x (74163 4 bit counters) a sig gen to produce a slow clock and a D type FF for a trigger.
Basically what i have designed it to do is count to the binary sequence 0010 1011 and then reset. The circuit is triggered by the push button, when the sequence is reached the count should stop and wait for another trigger.
Its actually reseting on the sequence 0000 0001 and i cant figure out why. It should work in my eyes, perhaps its something stupid i cant see.
The leds are just there for me to see a visual output.
