When you are ready to program your butterfly remember that it does so through a bootloader.
You have to get the bootloader "ready" in a certain way...

ADC Resolution Problem & can't read ADCH Are you saying AVCC must be powered regardless, even if my VREF is selected as AREF?
Measured AVCC was 2.9V.

ADC Resolution Problem & can't read ADCH Measuring across on C102 on ARef gives me 2.85V, after I switch on PF3(VCP).
I'm going to take another look soon. Thanks to all you guys for the resposes!

ADC Resolution Problem & can't read ADCH I tried #1 only to have my max value at 185 again. #2 gives me a max of 46, and #3 gives me a max of 185.
I have no idea why it's not working. off to bed, i'll try again tomm.

ADC Resolution Problem & can't read ADCH yea. hehe.. i got frustrated and took a random guess. i will go back to 8 and keep trying in the meantime.
how does it overflow? it's a temp value that's rewritten each loop...
Butterfly A/D Code for Temp Sensor i'm doing some ADC debugging and i'm afraid i might have blown something up.
Is it possible to trash the ADC circuity by wiring 3v with no resistor?
:oops:
