I've got everything together properly (or so I thought) and tossed in a simple design (40 lines). Success.
However, if I try for a longer design (160 lines, or even 80) AVRDude tells me it's been sent propery and verified, but when I return to the unit, I either get the top and bottom LEDs on constantly, or the second bottom LED on dimly.
If I go back to a shorter message, it works. I understood that we should be able to run with 500 lines or more.
Any suggestions? This is a miniPOV3 and Windows XP.
