    I read your book with great interest, thank you for publishing it. Like everyone else who bites off more than they can chew, I’m trying to build an LED music display. I’m hoping to use common anode RGB LEDs and assume that I use the schematic “usart_mspim-no_border_multiple.pdf” and wire up each LED to consecutive outputs of the 5940 ie 28-R, 1-G and 2-B and so on. I also have a nice 12V 4A power supply and want to use 3 LEDs in parallel for each “line” is this too much for the 5940 and would I still set the current to 20mA or use 60mA. I have lots of N channel mosfets, could I use these to wire it up as per the common cathode schematic? Thank for helping a beginner.

No public wish lists :(
