Class List
Here are the classes, structs, unions and interfaces with brief descriptions:
[detail level 12]
 CADS1x15 Represents an ADS1015 or ADS1115 Analog to Digital Converter. Values are read with ADS1x15RawValue or ADS1x15Voltage CADS1x15RawValue Used to read the raw output of the ADS1x15, which is an integer between 0 and 32,768. If you want the voltage that was the input to the ADS1x15 (because voltage is what the ADS1x15 actually reads), use ADS1x15Voltage instead CADS1x15Voltage Reads the raw output of the ADS1x15 (an integer between 0 and 32,768) and converts it back into the voltage that was actually read by the chip. If you want the raw output itself, use ADS1x15RawValue instead CAirDensity Transforms temperature, relative humidity and pressure in air density CAnalogInput Sensor for reading the MCU analog input pins CAnalogVoltage A transform that takes the output of an analog-to-digital converter and outputs the voltage that went into it. (This can be the built-in ADC on the ESP, or it can be an external ADC like the ADS1015/1115.) CAngleCorrection Add a value to an angle input (in radians). The output value is wrapped to a range between [0, 2*pi]. This transform is useful for correcting e.g. a heading or a wind direction reading CBaseAnalogReader Used by AnalogInput to properly read the very different ADC's of the ESP8266 and ESP32 CBaseBlinker A base class for LED blinker classes CBME280 Represents an ADAfruit (or compatible) BME280 temperature / pressure / humidity sensor CBME280Value BME280Value reads and outputs the specified value of a BME280 sensor CBMP280 BMP280 represents an ADAfruit or compatible BMP280 temperature & pressure sensor CBMP280Value BMP280Value reads and outputs the specified value of a BMP280 sensor CChangeFilter A numeric passthrough transform that will only pass that value through if it is "sufficiently different" from the last value passed through CClickType ClickType is a transform that consumes button clicks and translates them as events of type ClickTypes CConfigurable An object that is capable of having configuration data that can be set remotely using a RESTful API, and can be persisted to the local file system ►CCurveInterpolator Uses a collection of input/output samples that approximate a non-linear curve and outputs a value on that curve. The output is the linear interpolation between the two sample points that the input falls between. It is used primarily for non-linear analog gauges such as temperature gauges and oil pressure gauges, which get their input from analog sensors that are variable resistors CDallasTemperatureSensors Finds all 1-Wire temperature sensors that are connected to the ESP and makes the address(es) and temperature data available to the OneWireTemperature class CDebounceTemplate Implements debounce code for a button or switch CDewPoint Transforms temperature and relative humidity in dew point temperature CDifference CDigitalInput DigitalInput is the base class for reading a digital GPIO pin CDigitalInputChange DigitalInputChange is meant to report when a digital pin changes its state CDigitalInputCounter DigitalInputCounter counts interrupts and reports the count every read_delay ms CDigitalInputState DigitalInputState reports the state of a digital pin every read_delay ms CDigitalOutput Sets a GPIO pin to whatever the input is (true = HIGH, false = LOW), and passes the value on to the next ValueConsumer CEnable Classes that implement "Enable" will have their enable() method called automatically at startup when the SensESP app itself is enabled. The optional priority allows for certain classes to be initialized first. The default priority is zero. A higher priority (i.e. greater than zero) will be enabled before a lower one (i.e. less than zero) CENUVector CEvenBlinker An LED blinker class that blinks the LED 50% off, 50% on, at a given period CFreeMem Reports the current amount of unused memory of the ESP CFrequency Transforms its input into frequency (Hz: cycles per second) CGPGGASentenceParser CGPGLLSentenceParser CGPRMCSentenceParser CGPSInput Support for a GPS module communicating with NMEA-0183 messages over a serial interface CHeatIndexEffect Transforms heat index temperature to heat index effect CHeatIndexTemperature Transforms temperature and relative humidity in heat index temperature CHTTPServer Handles external interactions with the device via the web interface CHysteresis Hysteresis function CINA219 Represents an ADAfruit (or compatible) INA219 High Side DC Current Sensor CINA219Value INA219Value reads and outputs the specified value of an INA219 sensor CIntegerSensor A Sensor whose output is an integer CIntegerThreshold Translates an integer value into a boolean value, which depends on whether the integer value is "in range" or "out of range" CIntegratorT Integrator integrates (accumulates) the incoming values CIPAddrDev Reports the IP address of the ESP once it's connected to wifi CLambdaConsumer Provides an easy way of calling a function based on the output of any ValueProducer CLambdaTransform Construct a new transform based on a single function CLinear Performs a linear transform on the input value: output = (input * multiplier) + offset CMAX31856Thermocouple Reads the temperature from an Adafruit MAX31856 (or compatible) thermocouple breakout board. Communicates with the ESP via SPI CMedian Outputs the median value of sample_size inputs CMovingAverage Outputs the moving average of the last sample_size inputs CNetworking Manages the ESP's connection to the Wifi network CNMEAData CNMEAParser CNumericSensor A Sensor whose output is a float CNumericThreshold Translates a float value into a boolean value, which depends on whether the float value is "in range" or "out of range" CObservable A base class which allow observers to attach callbacks to themselves. The callbacks will be called when the observable needs to notify the observers about some state change CObservableValue A value that notifies its observers if it gets changed COneWireTemperature Used to read the temperature from a single 1-Wire temperature sensor. If you have X sensors connected to your ESP, you need to create X instances of this class in main.cpp CParamInfo CPatternBlinker A blinker that blinks the LED according to a defined repeating pattern CPeriodicBlinker A base class for periodic blinkers CPosition CPressRepeater A transform that takes boolean inputs and adds button behaviors familiar to many device end users CPSTI030SentenceParser CPSTI032SentenceParser CPSTISentenceParser CPWMOutput Provides a cross platform mechanism for generating Pulse Width Modulation signals over one or more GPIO pins on the MCU CRatioBlinker A periodic blinker that defines both the on-ratio and the period length CRepeatReport Ensures that values that do not change frequently are still reported at a specified maximum silence interval. If the value has not changed in max_silence_interval milliseconds, the current value is emmitted again CRgbLed A special device object that can be used to control a multi-channel color rgb LED light using up to 3 digital output channels. A "color" is defined using the standard 24 bit color depth numbers composed of three 8 bit channels for Red, Green, and Blue (see https://techterms.com/definition/rgb) CRoundToInt Takes as its input a float, rounds it to the nearest whole number, then outputs it as an int CSensESPApp CSensESPAppBuilder A class for quickly configuring a SensESP application object before wiring up your sensors CSensor The base class for all sensors. Used only as a base class - never instantiated directly in a project CSentenceParser CSHT31 SHT31 represents an ADAfruit (or compatible) SHT31 temperature & humidity sensor CSHT31Value SHT31Value reads and outputs the specified value of an SHT31 sensor CSKDelta CSKEmitter A class that produces Signal K output to be forwarded to the Signal K server (if the system is connected to one). Signal K is reported via the as_signalK() method CSKListener An Obervable class that listens for Signal K stream deltas and notifies any observers of value changes. This serves as a base class for code that needs to listen to the stream, with the most common descendant being SKValueListener CSKMetadata Holds Signal K meta data that is associated with the sk_path an SKEmitter class may optionally send to the server. According to the official Signal K specification: "All keys in the Signal K specification must have a description, and where the key is a numeric value it must have units". Thus, any paths that you output that are not already part of the official Signal K specification should have these two fields defined as metadata CSKOutput A specialized transform whose primary purpose is to output Signal K data on the Signal K network CSKOutputNumeric A special class for sending numeric values to the Signal K server on a specific Signal K path CSKOutputTime CSKPutListener An Obervable class that listens for Signal K PUT requests coming over the websocket connection and notifies observers of the change CSKPutRequest Used to send requests to the server to change the value of the specified path to a specific value according to the specification at https://signalk.org/specification/1.5.0/doc/put.html CSKPutRequestBase A base class for all template variations of the PUT request class SKPutRequest. This base class keeps the compiler from generating reduntant object code for common functionality of each template version CSKPutRequestListener An object that listens for PUT requests to come in for the specified SignalK path. The value is then emitted for further processing ►CSKRequest A base class for all objects that are capable of sending "requests" to the SignalK server (and optionally receiving the responses) according to the specification located at https://signalk.org/specification/1.5.0/doc/request_response.html CSKValueListener An ValueProducer that listens to specific Signal K paths and emits its value whenever it changes ►CSmartSwitchController A high level transform designed to control a digital output (such as a relay) via manual button presses or programatic commands CStringSensor A Sensor whose output is a String CSymmetricTransform A common type of transform that consumes, transforms, then outputs values of the same data type CSystemHz Reports the current clock speed of the ESP CSystemStatusController Base class for a controller that can react to system status events CSystemStatusLed Consumes the networking and websocket states and delta counts and updates the device LED accordingly. Inherit this class and override the methods to customize the behavior CTextToTruth Consumes a string and outputs boolean "true" if the text represents a human readable version of "true" CThresholdTransform A Transform base class that translates the value of type C into value of type P. Base class for classes NumericThreshold and IntegerThreshold CTimeString Consumes a time_t time object and produces a human readable string of the time for UTC in ISO 8601 format CTransform The main Transform class. A transform is identified primarily by the type of value that is produces (i.e. a Transform is a ValueProducer that generates float values) CTransformBase The base class for all transforms. A transforms takes a value in, transforms it in some way, and outputs the transformed value CTruthToText Consumes a boolean value and outputs one the appropriate truth string specified in the constructor. This is the inverse of TextToTruth CTypecast Converts input from one data type to another, then outputs the new type CUltrasonicDistance Reads a DYP-A02YYWM-V1.0 (and possibly other types) ultrasonic sensor and outputs the number of microseconds that it takes the sound wave to bounce off an object and return to the sensor CUptime Reports the number of seconds since the last restart of the ESP CValueConsumer A base class for piece of code (like a transform) that accepts data for input. ValueConsumers can accept one or more input values via the set_input() method. They are connected to ValueProducers via the connect_to() method CValueProducer A base class for any sensor or piece of code that outputs a value for consumption elsewhere. CVoltageDividerR1 Uses the voltage divider formula to calculate (and output) the resistance of R1 in the circuit CVoltageDividerR2 Uses the voltage divider formula to calculate (and output) the resistance of R2 in the circuit CVoltageMultiplier OBSOLETE: Since you can now apply an "output_scale" to the AnalogInput sensor, you don't need this transform anymore. See the description of "output_scale" in analog_input.h CWifiSignal Reports the current strength of the wifi signal that the ESP is connected to CWSClient The websocket connection to the Signal K server
