My new PAR Meter PCB's arrived yesterday along with more parts from DigiKey, so needless to say- I'm ready to build another batch. One of the PCB's that came in is an Arduino shield that I designed to allow me to burn boot loaders and program blank Atmega 328P-au micro-controllers directly from my Duemilanove. The burning process is fully automatic and doesn't ever require a computer. I managed to assemble one and burn 25 chips last night!The shield is set up to accept chips in the DIP28 and DIP32 package and has a FIT1 input for burning the main sketch. I have a few of these shields left over and will share them with anyone interested in having one.
Here's a photo of the Programming shield/TQFP adapter on top of my Duemilanove.
