#define BUTTON_PIN GPIO_PUSH_BUTTON_0

ID of button input I/O pin.

This pin is checked for active low status when the example is waiting for user input, i.e., after the external voltage supply has been adjusted.

Note: This is push button 0 on the A3BU Xplained.

Referenced by wait_for_button().

#define INPUT_PIN ADCCH_POS_PIN0

ID of ADC input pin.

This pin is the one used for all measurements with the ADC.

Note: This is pin 1 (PB0) on the A3BU Xplained J2 header

Referenced by main().

#define LED1_PIN LED0_GPIO

ID of LED 1 control I/O pin.

This pin is driven low when the example is waiting for the external voltage supply to be adjusted to 0 Volts. It is driven high once calibration is done.

Note: This is LED0 on the A3BU Xplained.

Referenced by main().

#define LED2_PIN LED1_GPIO

ID of LED 2 control I/O pin.

This pin is driven low when the example is waiting for the external voltage supply to be adjusted to 0.9 Volts. It is driven high once calibration is done.

Note: This is LED1 on the A3BU Xplained.

Referenced by main().

#define OUTPUT_STR_SIZE 32

Note: Size of the string output to the display

Referenced by ISR().

#define OVERSAMPLING_FACTOR 6

Number of calibration samples, as exponent of 2.

This determines the number of samples used for the oversampling. It is given as an exponent of 2, i.e., setting this factor to 3 gives 2^3 = 8 samples.

Note: This gives 2^6 = 64 samples.
