Macro Definition Documentation

◆ DEBUG_OUT

#define DEBUG_OUT

The debug output.


Use #define DEBUG_OUT Serial to print debugging information to the serial monitor.

Note
Printing debug information can slow down the program dramatically.

Definition at line 27 of file Settings.hpp.

◆ FATAL_ERRORS

#define FATAL_ERRORS

Exit when encountering an error, instead of trying to recover (recommended).

Definition at line 32 of file Settings.hpp.

Typedef Documentation

◆ ANALOG_FILTER_TYPE

using ANALOG_FILTER_TYPE = uint16_t

The unsigned integer type to use for analog inputs during filtering.

Variable Documentation

◆ defaultBaudRate

constexpr unsigned long defaultBaudRate = 115200
constexpr

The default baud rate for debug output.

Definition at line 38 of file Settings.hpp.

◆ ADC_BITS

constexpr uint8_t ADC_BITS = ADC_RESOLUTION
constexpr

The bit depth to use for the ADC (Analog to Digital Converter).

By default, the maximum supported resolution is used, but if you need it for compatibility with other code that expects the default 10-bit resolution, you can use

constexpr uint8_t ADC_BITS = 10;
constexpr uint8_t ADC_BITS
The bit depth to use for the ADC (Analog to Digital Converter).
Definition: Settings.hpp:55

If the library doesn't know your specific hardware, it defaults to 10 bits. This might not be the optimal resolution, so it's best to add the actual resolution to Hardware/ADCConfig.hpp.

Definition at line 55 of file Settings.hpp.

◆ ANALOG_FILTER_SHIFT_FACTOR

constexpr uint8_t ANALOG_FILTER_SHIFT_FACTOR = 2
constexpr

The factor for the analog filter:
Difference equation: \( y[n] = \alpha\cdot x[n] + (1-\alpha)\cdot y[n-1] \) where \( \alpha = \left(\frac{1}{2}\right)^{ANALOG\_FILTER\_SHIFT\_FACTOR} \).

◆ LONG_PRESS_DELAY

constexpr unsigned long LONG_PRESS_DELAY = 450
