[En-Nut-Discussion] Need Analog Help

[Daniel Buergin]

Hi

I've a Motorla 4115A Pressure Sensor attached at
Port PF0 of the ADC. I measure 3.799V by Hand at
this Port. The Board is Ethernut 2.1b with NutOS 3.9.8

But with my Program, i only get 1023 ticks.

Program-Fragment:

u_short adc_value = 0;

ADCInit();
ADCSetRef(AREF);
ADCSetMode(SINGLE_CONVERSION);
ADCSetChannel(ADC0);
ADCSetPrescale(128);

for(;;){
  ADCStartConversion();
  while (ADCRead(&adc_value))
     NutThreadYield();

  printf("ADC: %u\n",adc_value);
}

What am i doing wrong ? 

Thanks in advance

Daniel
