The RGB dash project

[Ivan141]

Well, I figured out that the MCU is good, and have got some test code in there finally.





A couple of observations:

-The power draw is quite big, I can see it has a slight dip when the LED's are at full brightness. I haven't even connected all boards yet so I'm going to have to measure how much the voltage drops and make sure it's not too much. I'm curious what's using all the power since all LED's together shouldn't use more than 1A (and the supply is supposedly good up to 3A).

-As a result of the power usage, the power regulator gets quite hot. Will need a heat sink attached to it when installed.

-I'm bummed about the 3 dollar FTDI chip being toasted, because I haven't got any external inputs at my disposal to change settings with while the board is running. The idea was to be able to do this using a USB cable, so I'm hoping I'll get the next one to work better.
