I started this week by converting Neil's helloFTDI board to Eagle so members of the class could use Eagle to edit it. The board file is here and the schematic is here. Then to fulfill this week's assignment to add a button and LED, I updated my old Fabduino board with an auto reset circuit and an FDTI connector
The board file is here and the schematic is here. I programmed it in both Arduino and Modkit. I plan to write some examples that just use avr-libc and avr-gcc.
