Uploading the Software

[NeilR]

So, now with 12V applied I get the proper 3.3V at the point on the board marked "3.3V" and at pin 1 of the ATMEGA328.  I connected the FTDI and verified I could upload a sketch to the 328 by uploading the Blink sketch from the Arduino examples.  I tested it by measuring the voltage at pin 19 - it alternated between zero and 3.3V as expected.  Definitely making progress!  But still some issues with RN52 programming.  I'm going to post on the "How to: RN52 programming and configuration" because the issues are similar to others on that thread.
