Will not enter charging state

[GoogleCodeExporter]

SYMPTOMS/ENVIRONMENT:
After plugging vehicle into the open-evse (v4 hardware & v1.0.9 firmware), the 
state is perpetually "EV Connected - EVSE Ready".  The EVSE will not advance to 
the "Charging" state.

Additional symptoms are the boot up sequence takes about 10 seconds (as opposed 
to about 1 second normally) and it causes the pilot pwm frequency to be ~60Hz 
instead of 1kHz (seen with a DMM or oscilloscope).

ISSUE:
This occurred after programming a virgin atmega328p using the ICSP and the 
Arduino IDE by following the instructions at 
https://code.google.com/p/open-evse/wiki/LoadingFirmware and 
http://blog.lincomatic.com/?p=10.

The reason for this occurring is that following this specific programming 
process, the AVR fuses are not set causing the micro-controller's clock to run 
too slow.

WORKAROUND:
Follow the instructions specifically for setting the fuses on 
https://code.google.com/p/open-evse/wiki/AVRDUDE

That is an odd oversight. Fuse bit settings are needed no matter what method is 
used. I edited the LoadingFirmware page to include a mention of setting the 
fuses.
