Detailed Description

Models a Timer Latch DD-MPB, a.k.a. Timer Switch (TiLDD-MPB).

The Timer switch keeps the On state since the moment the signal is stable (debouncing + delay process), and until the unlatch signal is provided by a preset timer started immediately after the MPB has passed the debounce & delay process. The time count down might be reset by pressing the MPB before the timer expires by optionally configuring the object to do so with the provided method. The total count-down time might be changed by using a provided method.

class TmLtchMPBttn

Constructor & Destructor Documentation

◆ TmLtchMPBttn()

TmLtchMPBttn::TmLtchMPBttn ( const uint8_t & mpbttnPin,
const unsigned long int & svcTime,
const bool & pulledUp = true,
const bool & typeNO = true,
const unsigned long int & dbncTimeOrigSett = 0,
const unsigned long int & strtDelay = 0 )

Class constructor.

Parameters
srvcTimeThe service time (time to keep the isOn attribute flag raised).
Note
For the other parameters see DbncdDlydMPBttn(const uint8_t, const bool, const bool, const unsigned long int, const unsigned long int)

Member Function Documentation

◆ getSrvcTime()

const unsigned long int TmLtchMPBttn::getSrvcTime ( ) const

Returns the configured Service Time.

Returns
The current Service Time setting in milliseconds

◆ setSrvcTime()

bool TmLtchMPBttn::setSrvcTime ( const unsigned long int & newSrvcTime)

Sets a new value to the Service Time attribute.

Parameters
newSrvcTimeNew value for the Service Time attribute
Note
To ensure a safe and predictable behavior from the instantiated objects a minimum Service Time setting guard is provided, ensuring data and signals processing are completed before unlatching process is enforced by the timer. The guard is set by the defined _MinSrvcTime constant.
Return values
trueif the newSrvcTime parameter is equal to or greater than the minimum setting guard, the new value is set.
falseThe newSrvcTime parameter is less than the minimum setting guard, the srvcTime attribute was not changed.
Attention
The "service time completed", as every other timing related behavior of the MPBttn objects, is computed and updated by the attached timer, and the checking period is the one set by the begin(unsigned long int) method. There must be some correlation between both values. If the timer is set to a very high value, the "service time" will not be checked so frequently, so the service time will be completed, but the MPBttn status will not be updated untill next timer update calling. That's also the reason why each MPBttn object might be configured with different update periods of time: to check more frequently on those objects with short service times, less frequently on those objects that don't require to be checked so frequently, and avoid the time loss by checking every MPBttn at it's optimal pace.
Here is the caller graph for this function:

◆ setTmerRstbl()

void TmLtchMPBttn::setTmerRstbl ( const bool & newIsRstbl)

Configures the timer for the Service Time to be reseted before it reaches unlatching time.

If the isResetable attribute flag is cleared the MPB will return to Off state when the Service Time is reached no matter if the MPB was pressed again during the service time period. If the attribute flag is set, pressing the MPB (debounce and delay times enforced) while on the On state resets the timer, starting back from 0. The reseting might be repeated as many times as desired.

Parameters
newIsRstblThe new setting for the isResetable flag.
