Did you notice the comment about the XT fuse, and then compare it
to your #use delay() frequency ?
What is your real crystal frequency ? Is it 4 MHz or 20 MHz ?
If it's 20 MHz, the XT fuse wo ... |

Tacq.....
The ADC takes _time_ to acquire a signal after a channel is selected. Depends on the impedance of the source, but typically 10 to 20uSec. You _must_ wait for this time after selecting a c ... |

They even have a Ge ... |
