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 reseted 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() [1/2]

TmLtchMPBttn::TmLtchMPBttn	(	GPIO_TypeDef *	mpbttnPort,
		const uint16_t &	mpbttnPin,
		const unsigned long int &	srvcTime,
		const bool &	pulledUp = true,
		const bool &	typeNO = true,
		const unsigned long int &	dbncTimeOrigSett = 0,
		const unsigned long int &	strtDelay = 0 )

Class constructor.

Parameters

srvcTime The service time (time to keep the isOn attribute flag raised).

Note: For the other parameters see DbncdDlydMPBttn(GPIO_TypeDef*, const uint16_t, const bool, const bool, const unsigned long int, const unsigned long int)

◆ TmLtchMPBttn() [2/2]

TmLtchMPBttn::TmLtchMPBttn	(	gpioPinId_t	mpbttnPinStrct,
		const unsigned long int &	srvcTime,
		const bool &	pulledUp = true,
		const bool &	typeNO = true,
		const unsigned long int &	dbncTimeOrigSett = 0,
		const unsigned long int &	strtDelay = 0 )

Class constructor.

Parameters

mpbttnPinStrct	GPIO port and Pin identification defined as a single gpioPinId_t parameter.
srvcTime	The service time (time to keep the isOn attribute flag raised).

Note: For the rest of the parameters see DbncdMPBttn(GPIO_TypeDef*, const uint16_t, const bool, const bool, 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

newSrvcTime New 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

true	if the newSrvcTime parameter is equal to or greater than the minimum setting guard, the new value is set.
false	The newSrvcTime parameter is less than the minimum setting guard, the srvcTime attribute was not changed.

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

newIsRstbl The new setting for the isResetable flag.
