Hi,
You connect those 2 devices to 2 separate analog-input channels (select 2 from AN0...AN7 pins).
In your code set those 2 pins as analog-inputs and set other ADC configurations as you need.
Then in your code first select one channel by configuring CHS2:CHS0 bits in ADCON0 register; then do the conversion; backup results.
Then select 2nd channel by configuring CHS2:CHS0 bits again and follow above sequence.
For more info on configurations see "ANALOG-TO-DIGITAL CONVERTER (A/D) MODULE" in datasheet.
Is this what you asked ?
