Hello. I just got in the sparkfun breakout board for the TLC5940. I haven't connected it to the propeller yet but plan on it this weekend. I had someone tell me that is not familiar with the 5940 that I should look at the Neopixel concept. I need to connect 48 RGB leds, the preferred LED will be SMT on my own board layout. The 5940 allows daisy chaining chips as well as the Neopixel drivers IC wmxxxx and both allow independent LED color control. This is a pretty simple project to color code some buttons. I have code snips for the Propeller for both ideas. Does anyone with experience with each have an opinion on which path to take? I like the 5940 since it is 16 outputs on one IC, so I can drive 6 RGB led's on one IC. 8 IC's will drive the 48 buttons LED's. Not sure about the Neopixel, but the 5949 allows to adjust brightness by adjusting all values up or down.
