Hi, I'm looking to make some christmas presents, from scratch, with my EE skills. I'm looking to gift some boards that I design and make. The boards will flash some LED's, maybe have some knobs to change colors on RGB leds, display a nice christmas message on an LCD, and play audio from a SD card.
I've been investigating TI microprocessors as I have the most experience with them. I'm looking for one with a DAC, as that will make things much easier. My google skills must be getting weak because I'm having trouble figuring out what resolution the dac should be so that the audio sounds good. Additionally, if anyone has ever done anything like this, what speed processor do you think is suitable? Ive found some microprocessors that would obviously do the trick, but they're about $25 a piece before I even pay for the board, the sd card slot, buttons, etc.
