So i am using the TLC5941 which is basically the TLC5940. I am using the library provided in the playground section of this site. My problem is that i can't get any leds to light up. i have probed all over my breadboard and from what I can tell, the 5941 is getting the commands and latching properly. I believe this to be true because when i measure the Serial Out pin with a voltmeter, i get spikes at regular intervals, which implies the latch has been pulled. I don't have a oscilloscope to confirm that. I wired it up exactly as how it is in the playground schematic.
Does anyone have any ideas about what I doing wrong. I am only trying to run one of the example programs, which i assume is working.
