I'm building a PCB with an ATMega chip.
In the past, I've used Sparkfun's FTDI breakout board to program the ATMega.
However, I'd like to implement the FTDI chip and USB port on my own PCB, thereby bypassing the need for the breakout board.
Can I simply copy the schematic from Sparkfun's model, plop the chip down on my board, and expect it to work? Or is there some firmware I need to load onto the chip before it is able to translate USB to serial?
