Hey guys!
I'm bulding a frequency counter, using 7 segment displays, 4511 display drivers, and 4029 decade counters. Each terminal count of the counter is the clock of the "next" counter, pretty simple.
Then I have a 1 Hz reference signal that I need to use to latch the 4511 output (to latch the displays) AND to reset the 4029 chips (the 4029 chips don't have a master reset, but I'm using an asynchronous paralel load of 0000 to "reset").
Thing is I'm not being able to do this :/ I need to FIRST "unlatch" the 4511, then "latch" it again to store the frequency that was counted in the previous second, and finally "reset" de 4029 chips throught the asynchronous paralel load. (because if I do it at the same time, the displays will always show 0000)
Thing is I'm trying to solve this issue for hours and still not being able to do this with flip flops or finding another solution. :/
Guys do you have any idea?
Thanks!
Miguel
