Debounced pin class that remembers the previous debounced state.
This allows clicks (a combination of press then release) to be identified. This class extends the basic DebouncedPin class to add the previous state.

◆ ClickerPin()
| able::ClickerPin::ClickerPin |
( |
uint8_t |
pin, |
|
|
uint8_t |
initState |
|
) |
| |
|
inlineprotected |
Protected constructor used by sub-classes.
Use a Button sub-class of this class instead of this class directly.
- Parameters
-
| pin | The pin to read from. |
| initState | The initial (un-pushed) state of the button. |
Definition at line 231 of file Pins.h.
◆ debounceTime()
| static uint8_t able::DebouncedPin::debounceTime |
( |
| ) |
|
|
inlinestaticinherited |
Return the pin debounce time.
- Returns
- The number of milliseconds of debounce time.
Definition at line 179 of file Pins.h.
◆ heldTime()
| static uint16_t able::DebouncedPin::heldTime |
( |
| ) |
|
|
inlinestaticinherited |
Return the pin held time.
- Returns
- The number of milliseconds after which a pin is held.
Definition at line 188 of file Pins.h.
◆ idleTime()
| static uint32_t able::DebouncedPin::idleTime |
( |
| ) |
|
|
inlinestaticinherited |
Return the pin idle time.
- Returns
- The number of milliseconds after which a pin is idle.
Definition at line 197 of file Pins.h.
◆ nextId()
| static uint8_t able::Pin::nextId |
( |
| ) |
|
|
inlinestaticprotectedinherited |
Return the next auto-assigned button identifier.
- Returns
- The next auto-assigned button identifier. Each call increases the auto-assigned identifier.
Definition at line 29 of file Pins.h.
◆ readPin()
| void able::ClickerPin::readPin |
( |
| ) |
|
|
inlineprotected |
Debounce the pin readings to get a stable state of the pin.
When the state changes, remember the previous state so clicks (press then release can be identified). Calls DebouncedPin::readPin() and monitors for a change in debounced state, remembering the previous state.
Definition at line 252 of file Pins.h.
◆ setDebounceTime()
| static void able::DebouncedPin::setDebounceTime |
( |
uint8_t |
debounceTime | ) |
|
|
inlinestaticinherited |
Set the debounce time for input pins.
Pins may read noise as buttons are pressed and released. This noise can be registered as multiple button presses in a short time period, confusing your program. The debounce time is the number of milliseconds to wait when a reading changes before using that reading. See https://docs.arduino.cc/built-in-examples/digital/Debounce for details on debounce.
- Parameters
-
| debounceTime | The number of milliseconds before a button state change is returned (default 50ms, max 255ms). |
Definition at line 98 of file Pins.h.
◆ setHeldTime()
| static void able::DebouncedPin::setHeldTime |
( |
uint16_t |
heldTime | ) |
|
|
inlinestaticinherited |
Set the held time for input pins.
If a button is pressed for longer than this time, it will be held.
- Parameters
-
| heldTime | The number of milliseconds for a held state (default 1s). |
Definition at line 108 of file Pins.h.
◆ setIdleTime()
| static void able::DebouncedPin::setIdleTime |
( |
uint32_t |
idleTime | ) |
|
|
inlinestaticinherited |
Set the idle time for input pins.
If a button is unpressed for longer than this time, it will be idle.
- Parameters
-
| idleTime | The number of milliseconds for an idle state (default 60s). |
Definition at line 118 of file Pins.h.
◆ autoId_
| uint8_t able::Pin::autoId_ = 0 |

Time required for button to be held.
Definition at line 206 of file Pins.h.
◆ idleTime_
| uint32_t able::DebouncedPin::idleTime_ = 60000 |
|
staticprotectedinherited |
Time required for button to be idle.
Definition at line 207 of file Pins.h.
◆ millisStart_
| unsigned long able::DebouncedPin::millisStart_ |
|
protectedinherited |
Debounce start timer to handle button transition.
Definition at line 210 of file Pins.h.

| uint8_t able::DebouncedPin::prevReading_ |
|
protectedinherited |
The previous pin reading, to monitor state transitions.
Definition at line 209 of file Pins.h.

| uint8_t able::ClickerPin::prevState_ |
|
protected |
Previous debounced reading of the pin.
