Enabling and disabling updatables | |
void | enable () |
Enable this updatable: insert it into the linked list of instances, so it gets updated automatically. | |
void | disable () |
Disable this updatable: remove it from the linked list of instances, so it no longer gets updated automatically. | |
bool | isEnabled () const |
Check if this updatable is enabled. | |
void | moveDown () |
Move down this element in the list. | |
static void | enable (UpdatableCRTP *element) |
Enable this updatable: insert it into the linked list of instances, so it gets updated automatically. | |
static void | enable (UpdatableCRTP &element) |

Public Member Functions | |
VolumeControl (const Array< AudioMixer4 *, N > &mixers, pin_t analogPin, float maxGain=1.0) | |
Create a new VolumeControl object. | |
void | update () override |
Read the potentiometer value, and adjust the gain of the mixers. | |
void | begin () override |
Initialize. | |
void | map (MappingFunction fn) |
Specify a mapping function that is applied to the raw analog value before setting the volume. | |
void | invert () |
Invert the analog value. | |

inline |
Create a new VolumeControl object.
mixers | An array of pointers to audio mixers. Only the pointers are saved, so the mixers should outlive this object. |
analogPin | The analog pin with the potentiometer connected. |
maxGain | The maximum gain for the mixers. |
Definition at line 37 of file VolumeControl.hpp.
Read the potentiometer value, and adjust the gain of the mixers.

|
inline |
Specify a mapping function that is applied to the raw analog value before setting the volume.
fn | A function pointer to the mapping function. This function should take the filtered analog value of \( 16 - \mathrm{ANALOG\_FILTER\_SHIFT\_FACTOR} \) bits as a parameter, and should return a value in the same range. |
