Hi I'm about to start wiring up an 8x8 rgb matrix I've bought from LEDSEE.COM . I've got a few questions before I start, to make sure I'm going about this the right way. Datasheet for the matrix is here -> http://www.aplomb.nl/Niels_skn/RGB%20FULL%20COLOR%20MATRIX.pdf I intend to use 2 TLC5940 ICs…

8x8 RGB Matrix + 2x TLC5940 + 4051?

or do I need to find a new darlington array?

You need to find a way to source current not sink it. Have you seen what I did in:-
