Hi there,

we're new to microprocessor programming and right now we are trying to
get an olimex LPC2148 to work with a Sharp Optical Sensor 2y0a02.
But it seems we are too dumb to get the A/D changer to work properly.

We already tested the sensor and it works correctly. We plugged the
sensor to the p0.30 / AD03 pin
See the code, laugh at us and please tell us where our mind-barrier lies
:)

#include<targets/lpc2000.h>
#include<stdio.h>


static int erg;
int main(void) {

PINSEL1&=~(1<<29);
PINSEL1|=(1<<28);

AD0CR|=(1<<3); // Kanal 3

AD0CR|=(1<<9);
AD0CR|=(1<<10);

AD0CR|=(1<<16);
AD0CR|=(1<<21);

while(1){
   if(AD0DR3&(1<<31)){
    erg=(short)(AD0DR3>>6);
    debug_printf("%i\n",erg);
  }
}

return(0);
}

I think you have mixed burst mode with polling mode.

Try not setting AD0CR|=(1<<16)
