All progress began with an idea

Aratti,
I have a 10uF cap on there now, but I went ahead and tried the 220uF - still no luck. I'm wondering since it is occurring on the last digit if a bit from the PIC to the MAX7221 is getting lost somewhere. I tried connecting a 0.1uF and a 10uF cap, at separate times, to the DIN pin on the MAX7221, but no luck there either. Anything else that might cause the d segment on the last digit not to light up? Thanks for all the help thus far.

Just a little wiring problem.
DIG0 and SEGD are connected.

Doh!
Darrel,
You made my day! Thank you! I troubleshot the heck out of the first breadboard I used so I didn't think to check for shorts on this one. Thanks again!!!

It was your very neat and organized breadboard that allowed me to find it.
Something to be proud of.

Darrel,
Thank you! I do take great pride in my wiring.I hope at some point in the future to try out your Instant Interrupts routine, as I read they're all the rage. Thanks again for your help!

Oh yes, apparently "rage" is part of it. (wasn't intentional)I hope at some point in the future to try out your Instant Interrupts routine, as I read they're all the rage.
However, when you do, I'll try to smooth out the bumps.
CYA soon,
DT
