    I added spaces:

    trisio= % 00010000

    It looks like it should work. Back up and write a program to blink an LED on GPIO.1 and 5. Just to test.

    Hi
    You are setting gpio.5 as input with trisio = 100000
    Only gpio.3 must be set to work as adc.
    Then the correct trisio = 1000. Or = 8

    Sorry, my mistake...
    I did not see the data sheet and I have not used this Pic.
    I read you need use AN3 as adc input and I assumed this was at Gpio.3.
    It is at Gpio.4, then you need set trisio.4 as input and the correspondent pin at Ansel.
    But Trisio.5 MUST BE CLEARED to work as output.
