ok , for some reason today when we were scoping to see what we were sending out, all of my bits were reverse.
so say for instance if i set outputdata[4]=1;
on the scope machine it would send out 1000000 instead of 00000001.
so that could be an issue. also on the scope machine we kept seeing extra bits , it would throw in a 1 0, so everytime the 1 0, i would se my next element of the array.
so i dont know whats thats all about.
then also my element [6] wasnt the correct sum, so im going to try one more thing and then say its a hardware issue. but you can assist me if you want.
