Type Name
virtual bool begin ()
bool calculateHarmonics (float * array, size_t n) const
bool calculateMetrics (Metrics & metrics, float gridVoltage, float loadResistance) const
virtual void end ()
float getDutyCycle () const
Get the power duty cycle configured for the dimmer by the user.
float getDutyCycleFire () const
Get the real firing duty cycle (conduction duty cycle) applied to the dimmer in the range [0, 1].
float getDutyCycleLimit () const
Get the power duty cycle limit of the dimmer.
float getDutyCycleMapped () const
Get the remapped power duty cycle from the currently user set duty cycle.
float getDutyCycleMax () const
Get the remapped "1" of the dimmer duty cycle.
float getDutyCycleMin () const
Get the remapped "0" of the dimmer duty cycle.
virtual float getPowerRatio () const
bool isEnabled () const
Check if the dimmer is enabled (if it was able to initialize correctly)
bool isOff () const
Check if the dimmer is off.
bool isOn () const
Check if the dimmer is on.
bool isOnAtFullPower () const
Check if the dimmer is on at full power.
virtual bool isOnline () const
Returns true if the dimmer is online.
void off ()
Turn off the dimmer.
void on ()
Turn on the dimmer at full power.
virtual bool setDutyCycle (float dutyCycle)
Set the power duty.
void setDutyCycleLimit (float limit)
Set the power duty cycle limit of the dimmer. The duty cycle will be clamped to this limit.
void setDutyCycleMax (float max)
Duty remapping (equivalent to Shelly Dimmer remapping feature). Useful to calibrate the dimmer when using for example a PWM signal to 0-10V analog convertor connected to a voltage regulator which is only working in a specific voltage range like 1-8V.
void setDutyCycleMin (float min)
Duty remapping (equivalent to Shelly Dimmer remapping feature). Useful to calibrate the dimmer when using for example a PWM signal to 0-10V analog convertor connected to a voltage regulator which is only working in a specific voltage range like 1-8V.
void setOnline (bool online)
Set the online status of the dimmer.
virtual const char * type () const
virtual ~Dimmer ()

Type Name
uint16_t getSemiPeriod ()
Get the semi-period in us used for the power LUT calculations. If LUT is disabled, returns 0.
void setSemiPeriod (uint16_t semiPeriod)

Public Functions Documentation

function begin

Enable a dimmer on a specific GPIO pin.

virtual bool Mycila::CycleStealingDimmer::begin () override

Warning:

Dimmer won't be enabled if pin is invalid

Implements Mycila::Dimmer::begin


function end

Disable the dimmer.

virtual void Mycila::CycleStealingDimmer::end () override

Warning:

Dimmer won't be destroyed but won't turn on anymore even is a duty cycle is set.

Implements Mycila::Dimmer::end


function getPin

Get the GPIO pin used for the dimmer.

inline gpio_num_t Mycila::CycleStealingDimmer::getPin () const


function setPin

Set the GPIO pin to use for the dimmer.

inline void Mycila::CycleStealingDimmer::setPin (
    gpio_num_t pin
) 


function type

inline virtual const char * Mycila::CycleStealingDimmer::type () override const

Implements Mycila::Dimmer::type


function ~CycleStealingDimmer

inline virtual Mycila::CycleStealingDimmer::~CycleStealingDimmer () 

Public Static Functions Documentation

function onZeroCross

static void Mycila::CycleStealingDimmer::onZeroCross (
    int16_t delayUntilZero,
    void * args
) 

Optional: Integration with a Zero-Cross Detection (ZCD) system

Callback to be called when a zero-crossing event is detected.

This is optional when using standard (sync) Solid State Relays (SSR) that only activate or deactivate when the AC voltage crosses zero. This is usually the behavior of most SSRs available on the market.

If you are using a Random Solid State Relay (SSR) or a TRIAC that can be triggered at any point in the AC cycle, then you need to set this callback so that the library knows when to fire and stop the SSR/TRIAC.

When using MycilaPulseAnalyzer library, this callback can be registered like this:

pulseAnalyzer.onZeroCross(Mycila::CycleStealingDimmer::onZeroCross);

  • When using your own ISR with the RobotDyn ZCD, you can call this method with delayUntilZero == 200 since the length of the ZCD pulse is about 400 us.
  • When using your own ISR with the ZCd from Daniel S, you can call this method with delayUntilZero == 550 since the length of the ZCD pulse is about 1100 us.
