ADC conversion using PIC 16f877a

hi,

can we assign any conversion channel to perform a conversion?
example: i have 2 ultrasonic range sensors and i am measuring the distance to a wall.

from tutorials, it say the first conversion can be done in channel 2. i.e.

distance_1=Adc_Read(2);

now i want to measure the distance using the secomd sensor..

distance_2=Adc_Read(?);

what do i use here??

its urgent guys.. please help..

cheerz,
satanas

    Adc_Read(2) is maybe read the analog input on channel 2 (RA2, that is pin 4 PIC16F877A). This is where your sensor connected. I said maybe, because it's depends the Adc_Read() function. I assume that is channel number.
    So, for second sensor, just put for the second sensor channel. I have sample program #-Link-Snipped-#.
