Set the ADFM bit in the ADCON1 register to 0 so that the A2D result is
left justified. The upper 8 bits of the 10 bit result will be in ADRESH.
You can ignore the lower 2 bits in ADRESL.

This will really put the stack in a spin :-)

Try

here    goto here


There's probably no need to initialise all ports etc to zero and then
call 'pic_init' that changes them again straight away. Just call
'pic_init' and the jobs done.


I wouldn't rely on the first A2D reading as you have tried to do it only
micro seconds after the PIC is turned on. Try waiting a few mS at least
so the port pins get a chance to settle down.
