## Detailed Description

Models a Slider Double Action LDD-MPB combo switch, a.k.a. off/on/dimmer, a.k.a. off/on/volume radio switch)(S-DALDD-MPB)

This is a subclass of the DALDD-MPB whose secondary behavior is analog to that of a Digital potentiometer (DigiPot) or a Discreet values increment/decrement register. That means that when in the second mode, while the MPB remains pressed, an attribute set as a register changes its value -the otptCurVal register-. When the timer callback function used to keep the MPB status updated is called -while in the secondary mode state- the time since the last call is calculated and the time lapse in milliseconds is converted into Steps, using as configurable factor the outputSliderSpeed in a pre-scaler fashion. At instantiation the outputSliderSpeed is configured to 1 (step/millisecond, i.e. 1 step for each millisecond). The resulting value in "steps" is then factored by the outputSliderStepSize, which holds the value that each step will modify the otptCurVal register. The implemented embedded behavior mechanisms of the class determine how the modification of the otpCurVal register will be made, and the associated effects to the instantiated object's attribute, such as (but not limited to):

- Incrementing otpCurVal register (by the quantity of steps multiplied by the step size) up to the "maximum value" setting.
- Decrementing otpCurVal register (by that quantity) down to the "minimum value" setting.
- Changing the modification's direction (from incrementing to decrementing or vice versa). The minimum and maximum values, the rate in steps/millisecond, the size of each step and the variation direction (sign of the variation, incrementing or decrementing) are all configurable, as is the starting value and the mechanism to revert the "direction" that includes:
- Revert directions in the next secondary mode entry.
- Automatically revert direction when reaching the minimum and maximum values setting.
- Revert direction by methods invocation (see setSldrDirDn(), setSldrDirUp(), swapSldrDir()).

class SldrDALtchMPBttn

## Constructor & Destructor Documentation

## ◆ SldrDALtchMPBttn()

SldrDALtchMPBttn::SldrDALtchMPBttn | ( | const uint8_t & | mpbttnPin,
|  | const bool & | pulledUp = true,
|  | const bool & | typeNO = true,
|  | const unsigned long int & | dbncTimeOrigSett = 0,
|  | const unsigned long int & | strtDelay = 0,
|  | const uint16_t | initVal = 0xFFFF )

Class constructor.

Parameters

  initVal | (Optional) Initial value of the wiper (taking the analogy of a potentiometer working parts), in this implementation the value corresponds to the Output Current Value (otpCurVal) attribute of the class. As the attribute type is uint16_t and the minimum and maximum limits are set to 0x0000 and 0xFFFF respectively, the initial value might be set to any value of the type. If no value is provided 0xFFFF will be the instantiation value.

Note
  For the remaining parameters see DbncdDlydMPBttn(const uint8_t, const bool, const bool, const unsigned long int, const unsigned long int)

Here is the call graph for this function:

## ◆ getFnWhnTrnOffSldrDirUp()

fncPtrType SldrDALtchMPBttn::getFnWhnTrnOffSldrDirUp | ( |  | ) |

Returns the function set to be called when the slider direction is set to be decrementing (down).

The function to be executed is an attribute that might be modified by the setFnWhnTrnOffSldrDirUpPtr() method, and is a function pointer to a function with the signature void (fncPtr*) ().

Returns
  fncPtrType A pointer to the function set to be called when the slider direction is set to be decrementing (down).

Return values

  nullptr | if there is no function set to be called when the slider direction is set to be decrementing (down).

## ◆ getFnWhnTrnOffSldrMax()

fncPtrType SldrDALtchMPBttn::getFnWhnTrnOffSldrMax | ( |  | ) |

Returns the function that is set to be executed every time the object's Output Current Value (otptCurVal) attribute changes after being equal to the Maximum Output Value attribute setting (otptValMax).

The function to be executed is an attribute that might be modified by the setFnWhnTrnOffSldrMaxPtr() method, and is a function pointer to a function with the signature void (fncPtr*) ().

Sets the output current value register.

The new value for the output current value register must be in the range otptValMin <= newVal <= otptValMax

Parameters

  newVal | The new value for the output current value register.

Returns
  The success in the value change

Return values

  true | The new value was within valid range, the output current value register is set to the parameter passed.
  false | The new value was outside valid range, the change was not made.

## ◆ setOtptSldrSpd()

bool SldrDALtchMPBttn::setOtptSldrSpd | ( | const uint16_t & | newVal | ) |

Sets the output slider speed (otptSldrSpd) attribute.

As described in the SldrDALtchMPBttn class definition, the otptSldrSpd value is the factor by which the time between two readings of the MPB pressing state in secondary mode is converted into "slider steps". At instantiation the value is set to 1, meaning 1 millisecond is equivalent to 1 step, the "**slowest**" speed configuration. Rising the value will make each millisecond represent more steps, making the change of current value faster.

Parameters

  newVal | The new value for the otptSldrSpd attribute.

Returns
  The success in the value of the attribute

Return values

  true | The parameter was a valid value, the attribute is set to the new value.
  false | The parameter is an invalid value, the attribute is not changed.

Note
  Making the otptSldrSpd equal to 0 would void the ability to change the slider value, so the range of acceptable values is 1<= newVal <= (2^16-1).

Warning
  A "wrong" combination of otptSldrSpd and otptSldrStpSize might result in value change between readings greater than the range set by the otptValMin and the otptValMax values. The relation between the four parameters must be kept in mind if the application developed gives the final user the capability to configure those values at runtime.

## ◆ setOtptSldrStpSize()

bool SldrDALtchMPBttn::setOtptSldrStpSize | ( | const uint16_t & | newVal | ) |

Sets the output slider step size (otptSldrStpSize) attribute value.

Parameters

  newVal | The new value for the outputSliderStepSize attribute.

Note
  The new value for the step size must be smaller or equal than the size of the valid range of otptCurVal attribute

Return values

  true | If newVal <= (otptValMax - otptValMin), the value of the outputSliderStepSize attribute is changed.
  false | Otherwise, and the value of the outputSliderStepSize attribute is not changed.

Note
  For the secondary function to work like a slider, the condition (newVal < ((_otptValMax - _otptValMin) / _otptSldrSpd)) must be kept
  For the secondary function to work like a slider or a toggle switch, the condition (newVal <= ((_otptValMax - _otptValMin) / _otptSldrSpd)) must be kept
  For the secondary function to work like a toggle switch, the condition (newVal = ((_otptValMax - _otptValMin) / _otptSldrSpd)) must be kept.

Warning
  As a consequence of the aforementioned notes, if both otptSldrStpSize and otptSldrSpd are being changed, the otptSldrSpd must be changed first to ensure the new otptSldrStpSize doesn't fail the range validation test included in this method.

## ◆ setOtptValMax()

bool SldrDALtchMPBttn::setOtptValMax | ( | const uint16_t & | newVal | ) |

Sets the output current value register maximum value attribute (otptValMax attribute).

The new value for the otptValMax attribute must be in the range otptValMin < newVal <= 0xFFFF

Parameters

  newVal | The new value for the otptValMax attribute.

Returns
  The success in the value change

Return values

  true | The new value was within valid range, the otptValMax attribute change was made.
  false | The new value was outside valid range, the change was not made.

Note
  Due to type constrains, the failure in the value change must be consequence of the selected newVal <= otptValMin

Warning
  If the otpValMax attribute intended change is to a smaller value, the otpCurVal might be left outside the new valid range (newVal < otpCurVal). In this case the otptCurVal will be changed to be equal to newVal, and so otptCurVal will become equal to otptValMax.

Here is the call graph for this function:

## ◆ setOtptValMin()

bool SldrDALtchMPBttn::setOtptValMin | ( | const uint16_t & | newVal | ) |

Sets the output current value register minimum value attribute (otptValMin attribute).

The new value for the otptValMin attribute must be in the range 0x0000<= newVal < otptValMax.

Parameters

  newVal | The new value for the otptValMin attribute.

Returns
  The success in the value change

Return values

  true | The new value was within valid range, the otptValMin attribute change was made.
  false | The new value was outside valid range, the change was not made.

Note
  Due to type constrains, the failure in the value change must be consequence of the selected newVal >= otptValMax

Warning
  If the otptValMin attribute intended change is to a greater value, the otptCurVal might be left outside the new valid range (newVal > otptCurVal). In this case the otptCurVal will be changed to be equal to newVal, and so otptCurVal will become equal to otptValMin.

Here is the call graph for this function:

## ◆ setSldrDirDn()

bool SldrDALtchMPBttn::setSldrDirDn | ( |  | ) |

Sets the value of the curSldrDirUp attribute to false.

The curSldrDirUp attribute dictates how the calculated output value change -resulting from the time lapse between checks, the otptSldrSpd and the otptSldrStpSize attributes- will be applied to the otptCurVal attribute.

- If curSldrDirUp = false, the output value change will be subtracted from otptCurVal, successively down to otptValMin.

Note
  If the method intends to set the curSldrDirUp to false when the otptCurVal = otptValMin the method will fail, returning false as result.

Returns
  The success in changing the slider direction

Return values

  true | The change of direction was successful
  true | The change of direction failed as the otptCurVal was equal to the extreme value

## ◆ setSldrDirUp()

bool SldrDALtchMPBttn::setSldrDirUp | ( |  | ) |

Sets the value of the curSldrDirUp attribute to true.

The curSldrDirUp attribute dictates how the calculated output value change -resulting from the time lapse between checks, the otptSldrSpd and the otptSldrStpSize attributes- will be applied to the otptCurVal attribute.

- If curSldrDirUp = true, the output value change will be added to otptCurVal, up to otptValMax.

Note
  If the method intends to set curSldrDirUp to true when the otptCurVal = otptValMax the method will fail, returning false as result.

Returns
  The success in changing the slider direction

Return values

  true | The change of direction was successful
  true | The change of direction failed as the otptCurVal was equal to the extreme value

## ◆ setSwpDirOnEnd()

void SldrDALtchMPBttn::setSwpDirOnEnd | ( | const bool & | newVal | ) |

Sets the value of the "Auto-Swap Direction on Ends" (autoSwpDirOnEnd) attribute.

The autoSwpDirOnEnd is one of the attributes that configures the slider behavior, setting what the MPB must do when reaching one of the output values range limits. If a limit -otptValMin or otptValMax- is reached while the MPBttn is kept pressed and in secondary mode, the otptCurVal register increment/decrement can be stopped until a change of direction is invoked through setSldrDirUp(), setSldrDirDn() or swpSldrDir() methods, or automatically through the "Auto-Swap Direction on Ends" (autoSwpDirOnEnd) and the "Swap Direction on MPB press" (autoSwpDirOnPrss). If the autoSwpDirOnEnd attribute is set (true) the increment direction of the otptCurVal will be automatically inverted when it reaches otptValMax or otptValMin. If it's not set the otptCurVal will not change value until one of the described alternative methods is invoked, or the MPB is released and pushed back if the autoSwpDirOnPrss is set -see setSwpDirOnPrss(const bool).

Parameters

  newVal | The new value for the autoSwpDirOnEnd attribute

## ◆ setSwpDirOnPrss()

void SldrDALtchMPBttn::setSwpDirOnPrss | ( | const bool & | newVal | ) |

Sets the value of the "Auto-Swap Direction On Press" (autoSwpDirOnPrss) attribute.

The autoSwpDirOnPrss is one of the attributes that configures the slider behavior, setting what the MPB must do when the MPB object enters in secondary mode, referring to the increment or decrement directions. If the autoSwpDirOnPrss attribute is set (true) the increment direction of the otptCurVal will be automatically inverted every time the MPB is pressed back into secondary mode. If the otptCurVal was incrementing when the MPB was last released. the otptCurVal will start decrementing the next time is pressed to enter secondary mode, and vice versa. If it's not set the otptCurVal will not change direction until it reaches one the limit values, or until one of the described alternative methods is invoked, or the MPB's autoSwpDirOnEnd attribute is set -see setSwpDirOnEnd(const bool) for more details.

Parameters

  newVal | The new value for the autoSwpDirOnPrss attribute

## ◆ swapSldrDir()

bool SldrDALtchMPBttn::swapSldrDir | ( |  | ) |

Inverts the current curSldrDirUp attribute value.

Whatever the previous value of the curSldrDirUp flag, the method invocation inverts it's value, and as a consequence the inverts the direction of the otptCurVal update. If it was incrementing it will start decrementing, and vice versa, considering all the other factors, attributes and attribute flags involved in the embedded object behavior (minimum and maximum settings, the direction changes if pressed, reaches limits, etc.)

Returns
  The new value of the curSldrDirUp attribute.
