hi please help me configure the adc using micro c for PIC16F877A microcontroller. please.....


i want to use 3 inputs for PORT A ....RA0/AN1 (PIN 2), RA1/AN1(PIN 3) , RA2/AN2/Vref-/CVref(PIN 4)
there is Vref at PIN 5 which is RA3/AN3/Vref+....



can some one lend me a code for this please.:smile::smile:
 

Configuration for ADC

Code: 
ADCON0 = 0x81;//Will work with 20Mhz Crystal
ADCON1 = 0xCA; //In this Configuration AN3 is Vref+ pin

Refer Datasheet for such settings..
And MikroC is has very good documentation..
I think u must not have any problem, if u read that properly
