Thank you again.
Then ADCIN is an instruction nobody should use in order to have precision?
Excuse me but I have another question, If I use the pins dedicated for AN2 and AN3 in another matters, will the ADC have the 5 volts of Vdd as reference as default? (I hope so because I have any pins left) Or I have to use necesarily AN2 and AN3 to specify that reference?
Have a good day or night.
