Dear Ale95,

Thanks a lot for your reply.

You have pinched my ear and made me realize the silly mistake I have done. But I do not realize why I labored to locate the mistake for a week and finally asked for your help.

However, I have been wise enough to redo the trouble area and have managed to ...

I already have two posts on 'Up down counter and 'Hex - decimal constant' with satisfactory responses.

I acknowledge help once by Eugine and another time by Hans Cadens.

Tis time I am stuck with a latching problem while building a simulating model for Victoria Dam spillway gate operations.

The ...

Dear Hans Cadans,

Thank you very much for the offer to bail me out!

I have downloaded the library and am going through the counters. I feel I have found what I want. I will comment after using one of your circuits or ask for more help.

Thank you again - Victoria

Please help me to modify an up/down counter with a count down cycle of from 9 to 0 and not from F to 0.

I have already succeeded in building the circuit with count up cycle of 0 to 9 avoiding A to F.

The relevant section of my logic circuit work is attached.

I am a mechanical Engineer and a ...

Dear Eugine,

Thank you very much for the tip and the advice which encouraged me. I hope to contact you in future when stuck.

With a further modification in mind, I wanted the clock to stop when the value of a new input constant is equal to the displayed value.

I succeeded, but the new 8-bit constant takes in only "Hexadecimal ...
