Ive been trying to get this to work all night without any luck. I can get it to display the required number of digits but they don't look right, I think the hexpat data is incorrect, is there any way I can check it or maybe my program isn't looking at the hexpat data, but I think it is. please...

Can someone please help with the following question. Thanks Develop a program for the Motorola MC68HC11 using the THRSim11 simulator software. The program is to display a number 10 digits long, one digit at a time, on a single 7 segment LED display. Each digit will be ON for 1 second and OFF...

The problem is I can't get the thing to work. I can get it to display the first 2 hexpat numbers and that's it, but I need it to display the student number, using the hexpat data, i think.

Hello Can someone please help with the following question. Thanks Develop a program for the Motorola MC68HC11 using the THRSim11 simulator software. The program is to display a number 9 digits long, one digit at a time, on a single 7 segment LED display. Each digit will be ON for 1 second...

So if you had a question on the number of IC's used, would the answer be 1 1/3 (three 3-input ANDs (one IC), and feed their outputs to a 3-input OR (1/3 IC)) or 2 IC's because is can't have 1/3 of an IC?( can you?)

Thanks heaps for the maps, they made me feel better about this project cause they were the same as I had. I was able to configure the arrangement using twice as many IC's + inverters, then you have specificed (around 20), Would you please be able to show or tell me how the arrangement can be...

Yes I successfully derived the equations from the kmaps. Thanks

Ive just completed a working design using 8 AND gates and 1 OR gate plus 4 inverters. Do the Inverters count as ic's? What did you use WEED?

P0=A'BC'D'+A'B'C'D+A'BCD+A'B'CD' P1=AB'C'D'+A'B'D+A'C'D P2=AB'C'D+A'B'C+A'CD' P4=A'C'D'+A'BC'+A'BD' P7=A'BCD+B'C'D'+AB'C' Ive tested these in micro cap and I not believe they are correct, have you tested them? Which IC's did you use to create your design?

Hi Im having trouble drawing the circuit in micro cap. Would someone please happy me with this or drop a few hints. Would it be correct in saying that I have to have 2 leds turn on for each of the outputs? Ive also been told that this circuit can be build with 8 or 9 ics only, do you...
