[En-Nut-Discussion] reading out analog values

[Ole Reinhardt]

Hi,

here is some very short sampel code. Only showing some of the
possibilities:

ADCInit();
ADCSetChannel(0);
ADCStartConversion();
while (ADCRead(&adc_value))
    NutThreadYield();
fprintf_P(uart, PSTR("Checked power 5V: %4.1f" NL), adc_value / 1023.0 *
5.0);

This is measuring the voltage at port f0. AREF should be connected to
+5V

Bye,

Ole
