Hello friends
I want to know if it is possible to use internal reference voltage(Vref+) for ADC of 2.048V for pic16F877a and Vref-=0? is there any code ?

Thanks

No.

The voltage reference, does not have enough output drive capability to drive the ADC. The ADC requires a reference able to deliver 150uA.

It is designed for use with the comparator.

This is why it is called the _comparator_ voltage reference.....

Best Wishes
