Can you please explain in more detail? Totally not understand what are you going to do.

You want to drive 7 segment using microcontroller?
Which part in not functioning? microcontroller or 7-segment?
Can show us some connection?

Finally, I think you can refer to another threadhttp://forum.cytron.com.my/viewtopic.php?f=21&t=10731, might get the answer there.

Hi, can you show us how you test the 7-segment manually? and which program do you referring to? Are you referring to Cytron DIY project? PR2?
