Really hope someone can help me!
I have a GENIE PIC circuit that I am using to create an up/down counter for a scoreboard. Pretty simple program and all is working well except when the first pulse goes to the 4029s the second chip is also getting a pulse so the first output reads '11' instead of '01' on the 2 7 seg displays (common cathode). This then delays the second chips could so the 10s unit is 1 out throughout the count so '19, 10, 21...'
I have tried a few configs including adding an OR Gate from the clock and carry out of the first chip to the enable of the second. It looks like the rising edge of that first pulse is the culprit.
Has anyone else had this problem? Any solutions you can offer? I have studies the 4029 data sheet and am truly stumped.
TIA!!
