 Introduction and wiki: https://www.letscontrolit.com/wiki/index.php/ESPEasy#Introduction
 
-**v2.0**
-:warning:This is the stable branch for the next upcoming ESPeasy release (2.0.0).:warning:
+**MEGA**
+:warning:This is the development branch of ESPEasy. All new untested features go into this branch. If you want to do a bugfix, do it on the stable branch, we will merge the fix to the development branch as well.:warning:
 
-If you're living on the edge and want the latest features and bugs, go to the development branch: https://github.com/letscontrolit/ESPEasy/tree/mega
-
-If you're a developer: Bug fixes go into this v2.0 branch, we will merge them back to the development branch.
+Next stable branch: https://github.com/letscontrolit/ESPEasy/tree/v2.0  (bug fixes only, since oct 2017))
 
 Check here to learn how to use this branch and help us improving ESPEasy: http://www.letscontrolit.com/wiki/index.php/ESPEasy#Source_code_development
 
-## Versions
 
-* v2.0-YYYYMMDD: These are the nightly builds. Once a day this is automaticly released whenever there are new changes. (this replaces the manual v2.0-devX release system)
-* v2.0.0-betaX: as soon as we THINK everything is fixed, we start beta testing.
-* v2.0.0-rcX: release candidates (almost stable)
-* v2.0.0: This will be the first stable release. After this we will use more standard numbering. Next bugfix release will probably be 2.0.1.
+## Automated binary releases
 
-## Firmware binary releases
+Every night our build-bot will build a new binary release: https://github.com/letscontrolit/ESPEasy/releases
 
-Binary development releases are here: https://github.com/letscontrolit/ESPEasy/releases
+The releases are named something like 'mega-20180102' (last number is the build date)
 
-Depending on your needs, we release different types of files.

+# Adafruit Unified Sensor Driver #
+
+Many small embedded systems exist to collect data from sensors, analyse the data, and either take an appropriate action or send that sensor data to another system for processing.
+
+One of the many challenges of embedded systems design is the fact that parts you used today may be out of production tomorrow, or system requirements may change and you may need to choose a different sensor down the road.
+
+Creating new drivers is a relatively easy task, but integrating them into existing systems is both error prone and time consuming since sensors rarely use the exact same units of measurement.
+
+By reducing all data to a single **sensors\_event\_t** 'type' and settling on specific, **standardised SI units** for each sensor family the same sensor types return values that are comparable with any other similar sensor.  This enables you to switch sensor models with very little impact on the rest of the system, which can help mitigate some of the risks and problems of sensor availability and code reuse.
+
+The unified sensor abstraction layer is also useful for data-logging and data-transmission since you only have one well-known type to log or transmit over the air or wire.
+
+## Unified Sensor Drivers ##
+
+The following drivers are based on the Adafruit Unified Sensor Driver:
+
+**Accelerometers**

+

+
+## How Does it Work? ##
+
+Any driver that supports the Adafruit unified sensor abstraction layer will implement the Adafruit\_Sensor base class.  There are two main typedefs and one enum defined in Adafruit_Sensor.h that are used to 'abstract' away the sensor details and values:
+
+**Sensor Types (sensors\_type\_t)**
+
+These pre-defined sensor types are used to properly handle the two related typedefs below, and allows us determine what types of units the sensor uses, etc.
+
+```
+/** Sensor types */
+typedef enum
+{
+  SENSOR_TYPE_ACCELEROMETER         = (1),
+  SENSOR_TYPE_MAGNETIC_FIELD        = (2),
+  SENSOR_TYPE_ORIENTATION           = (3),
+  SENSOR_TYPE_GYROSCOPE             = (4),
+  SENSOR_TYPE_LIGHT                 = (5),
+  SENSOR_TYPE_PRESSURE              = (6),
+  SENSOR_TYPE_PROXIMITY             = (8),
+  SENSOR_TYPE_GRAVITY               = (9),
+  SENSOR_TYPE_LINEAR_ACCELERATION   = (10),
+  SENSOR_TYPE_ROTATION_VECTOR       = (11),
+  SENSOR_TYPE_RELATIVE_HUMIDITY     = (12),
+  SENSOR_TYPE_AMBIENT_TEMPERATURE   = (13),
+  SENSOR_TYPE_VOLTAGE               = (15),
+  SENSOR_TYPE_CURRENT               = (16),
+  SENSOR_TYPE_COLOR                 = (17)
+} sensors_type_t;
+```
+
+**Sensor Details (sensor\_t)**
+
+This typedef describes the specific capabilities of this sensor, and allows us to know what sensor we are using beneath the abstraction layer.
+
+```
+/* Sensor details (40 bytes) */
+/** struct sensor_s is used to describe basic information about a specific sensor. */
+typedef struct
+{
+    char     name[12];
+    int32_t  version;
+    int32_t  sensor_id;
+    int32_t  type;
+    float    max_value;
+    float    min_value;
+    float    resolution;
+    int32_t  min_delay;
+} sensor_t;
+```
+
+The individual fields are intended to be used as follows:
+
+- **name**: The sensor name or ID, up to a maximum of twelve characters (ex. "MPL115A2")
+- **version**: The version of the sensor HW and the driver to allow us to differentiate versions of the board or driver
+- **sensor\_id**: A unique sensor identifier that is used to differentiate this specific sensor instance from any others that are present on the system or in the sensor network
+- **type**: The sensor type, based on **sensors\_type\_t** in sensors.h
+- **max\_value**: The maximum value that this sensor can return (in the appropriate SI unit)
+- **min\_value**: The minimum value that this sensor can return (in the appropriate SI unit)
+- **resolution**: The smallest difference between two values that this sensor can report (in the appropriate SI unit)
+- **min\_delay**: The minimum delay in microseconds between two sensor events, or '0' if there is no constant sensor rate
+
+**Sensor Data/Events (sensors\_event\_t)**
+
+This typedef is used to return sensor data from any sensor supported by the abstraction layer, using standard SI units and scales.
+
+```
+/* Sensor event (36 bytes) */
+/** struct sensor_event_s is used to provide a single sensor event in a common format. */
+typedef struct
+{
+    int32_t version;
+    int32_t sensor_id;
+    int32_t type;
+    int32_t reserved0;
+    int32_t timestamp;
+    union
+    {
+        float           data[4];
+        sensors_vec_t   acceleration;
+        sensors_vec_t   magnetic;
+        sensors_vec_t   orientation;
+        sensors_vec_t   gyro;
+        float           temperature;
+        float           distance;
+        float           light;
+        float           pressure;
+        float           relative_humidity;
+        float           current;
+        float           voltage;
+        sensors_color_t color;
+    };
+} sensors_event_t;
+```
+It includes the following fields:
+
+- **version**: Contain 'sizeof(sensors\_event\_t)' to identify which version of the API we're using in case this changes in the future
+- **sensor\_id**: A unique sensor identifier that is used to differentiate this specific sensor instance from any others that are present on the system or in the sensor network (must match the sensor\_id value in the corresponding sensor\_t enum above!)
+- **type**: the sensor type, based on **sensors\_type\_t** in sensors.h
+- **timestamp**: time in milliseconds when the sensor value was read
+- **data[4]**: An array of four 32-bit values that allows us to encapsulate any type of sensor data via a simple union (further described below)
+
+**Required Functions**
+
+In addition to the two standard types and the sensor type enum, all drivers based on Adafruit_Sensor must also implement the following two functions:
+
+```
+bool getEvent(sensors_event_t*);
+```
+Calling this function will populate the supplied sensors\_event\_t reference with the latest available sensor data.  You should call this function as often as you want to update your data.
+
+```
+void getSensor(sensor_t*);
+```
+Calling this function will provide some basic information about the sensor (the sensor name, driver version, min and max values, etc.
+
+**Standardised SI values for sensors\_event\_t**
+
+A key part of the abstraction layer is the standardisation of values on SI units of a particular scale, which is accomplished via the data[4] union in sensors\_event\_t above.  This 16 byte union includes fields for each main sensor type, and uses the following SI units and scales:
+
+- **acceleration**: values are in **meter per second per second** (m/s^2)
+- **magnetic**: values are in **micro-Tesla** (uT)
+- **orientation**: values are in **degrees**
+- **gyro**: values are in **rad/s**
+- **temperature**: values in **degrees centigrade** (Celsius) 
+- **distance**: values are in **centimeters**
+- **light**: values are in **SI lux** units
+- **pressure**: values are in **hectopascal** (hPa)
+- **relative\_humidity**: values are in **percent**
+- **current**: values are in **milliamps** (mA)
+- **voltage**: values are in **volts** (V)
+- **color**: values are in 0..1.0 RGB channel luminosity and 32-bit RGBA format
+
+## The Unified Driver Abstraction Layer in Practice ##
+
+Using the unified sensor abstraction layer is relatively easy once a compliant driver has been created.
+
+Every compliant sensor can now be read using a single, well-known 'type' (sensors\_event\_t), and there is a standardised way of interrogating a sensor about its specific capabilities (via sensor\_t).
+
+An example of reading the [TSL2561](https://github.com/adafruit/Adafruit_TSL2561) light sensor can be seen below:
+
+```
+ Adafruit_TSL2561 tsl = Adafruit_TSL2561(TSL2561_ADDR_FLOAT, 12345);
+ ...
+ /* Get a new sensor event */ 
+ sensors_event_t event;
+ tsl.getEvent(&event);
+ 
+ /* Display the results (light is measured in lux) */
+ if (event.light)
+ {
+   Serial.print(event.light); Serial.println(" lux");
+ }
+ else
+ {
+   /* If event.light = 0 lux the sensor is probably saturated
+      and no reliable data could be generated! */
+   Serial.println("Sensor overload");
+ }
+```
+
+Similarly, we can get the basic technical capabilities of this sensor with the following code:
+
+```
+ sensor_t sensor;
+ 
+ sensor_t sensor;
+ tsl.getSensor(&sensor);
+
+ /* Display the sensor details */
+ Serial.println("------------------------------------");
+ Serial.print  ("Sensor:       "); Serial.println(sensor.name);
+ Serial.print  ("Driver Ver:   "); Serial.println(sensor.version);
+ Serial.print  ("Unique ID:    "); Serial.println(sensor.sensor_id);
+ Serial.print  ("Max Value:    "); Serial.print(sensor.max_value); Serial.println(" lux");
+ Serial.print  ("Min Value:    "); Serial.print(sensor.min_value); Serial.println(" lux");
+ Serial.print  ("Resolution:   "); Serial.print(sensor.resolution); Serial.println(" lux");  
+ Serial.println("------------------------------------");
+ Serial.println("");
+```

+
+- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
+  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
+  something isn't working as expected.  In many cases the problem is a common issue
+  that you will more quickly receive help from the forum community.  GitHub issues
+  are meant for known defects in the code.  If you don't know if there is a defect
+  in the code then start with troubleshooting on the forum first.
+
+- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
+  check all of the steps and commands to run have been followed.  Consult the
+  forum if you're unsure or have questions about steps in a guide/tutorial.
+
+- **For Arduino projects check these very common issues to ensure they don't apply**:
+
+  - For uploading sketches or communicating with the board make sure you're using
+    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
+    very hard to tell the difference between a data and charge cable!  Try using the
+    cable with other devices or swapping to another cable to confirm it is not
+    the problem.
+
+  - **Be sure you are supplying adequate power to the board.**  Check the specs of
+    your board and plug in an external power supply.  In many cases just
+    plugging a board into your computer is not enough to power it and other
+    peripherals.
+
+  - **Double check all soldering joints and connections.**  Flakey connections
+    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
+
+  - **Ensure you are using an official Arduino or Adafruit board.** We can't
+    guarantee a clone board will have the same functionality and work as expected
+    with this code and don't support them.
+
+If you're sure this issue is a defect in the code and checked the steps above

+/* Maximum Lux: 88K */
+
+/*  This example shows how the interrupt system on the TLS2591
+ *  can be used to detect a meaningful change in light levels.
+ *  
+ *  Two thresholds can be set: 
+ *  
+ *  Lower Threshold - Any light sample on CHAN0 below this value
+ *                    will trigger an interrupt
+ *  Upper Threshold - Any light sample on CHAN0 above this value
+ *                    will trigger an interrupt
+ *                    
+ *  If CHAN0 (full light) crosses below the low threshold specified,
+ *  or above the higher threshold, an interrupt is asserted on the interrupt
+ *  pin. The use of the HW pin is optional, though, since the change can
+ *  also be detected in software by looking at the status byte via
+ *  tsl.getStatus().
+ *  
+ *  An optional third parameter can be used in the .registerInterrupt
+ *  function to indicate the number of samples that must stay outside
+ *  the threshold window before the interrupt fires, providing some basic
+ *  debouncing of light level data.
+ *  
+ *  For example, the following code will fire an interrupt on any and every
+ *  sample outside the window threshold (meaning a sample below 100 or above
+ *  1500 on CHAN0 or FULL light):
+ *  
+ *    tsl.registerInterrupt(100, 1500, TSL2591_PERSIST_ANY);
+ *  
+ *  This code would require five consecutive changes before the interrupt
+ *  fires though (see tls2591Persist_t in Adafruit_TLS2591.h for possible
+ *  values):
+ *  
+ *    tsl.registerInterrupt(100, 1500, TSL2591_PERSIST_5);

+//
+// DISCLAIMER:
+// This software is furnished "as is", without technical support, and with no
+// warranty, express or implied, as to its usefulness for any purpose.
+//
+// BACKGROUND:
+// When I first received an ultrasonic sensor I was not happy with how poorly
+// it worked. Quickly I realized the problem wasn't the sensor, it was the
+// available ping and ultrasonic libraries causing the problem. The NewPing
+// library totally fixes these problems, adds many new features, and breaths
+// new life into these very affordable distance sensors.
+//
+// FEATURES:
+// * Works with many different ultrasonic sensors: SR04, SRF05, SRF06, DYP-ME007, URM37 & Parallax PING))).
+// * Compatible with the entire Arduino line-up (and clones), Teensy family (including $19 96Mhz 32 bit Teensy 3.2) and non-AVR microcontrollers.
+// * Interface with all but the SRF06 sensor using only one Arduino pin.
+// * Doesn't lag for a full second if no ping/echo is received.
+// * Ping sensors consistently and reliably at up to 30 times per second.
+// * Timer interrupt method for event-driven sketches.
+// * Built-in digital filter method ping_median() for easy error correction.
+// * Uses port registers for a faster pin interface and smaller code size.
+// * Allows you to set a maximum distance where pings beyond that distance are read as no ping "clear".
+// * Ease of using multiple sensors (example sketch with 15 sensors).
+// * More accurate distance calculation (cm, inches & uS).
+// * Doesn't use pulseIn, which is slow and gives incorrect results with some ultrasonic sensor models.
+// * Actively developed with features being added and bugs/issues addressed.
+//
+// CONSTRUCTOR:
+//   NewPing sonar(trigger_pin, echo_pin [, max_cm_distance])
+//     trigger_pin & echo_pin - Arduino pins connected to sensor trigger and echo.
+//       NOTE: To use the same Arduino pin for trigger and echo, specify the same pin for both values.
+//     max_cm_distance - [Optional] Maximum distance you wish to sense. Default=500cm.
+//
+// METHODS:
+//   sonar.ping([max_cm_distance]) - Send a ping and get the echo time (in microseconds) as a result. [max_cm_distance] allows you to optionally set a new max distance.
+//   sonar.ping_in([max_cm_distance]) - Send a ping and get the distance in whole inches. [max_cm_distance] allows you to optionally set a new max distance.
+//   sonar.ping_cm([max_cm_distance]) - Send a ping and get the distance in whole centimeters. [max_cm_distance] allows you to optionally set a new max distance.
+//   sonar.ping_median(iterations [, max_cm_distance]) - Do multiple pings (default=5), discard out of range pings and return median in microseconds. [max_cm_distance] allows you to optionally set a new max distance.
+//   NewPing::convert_in(echoTime) - Convert echoTime from microseconds to inches (rounds to nearest inch).
+//   NewPing::convert_cm(echoTime) - Convert echoTime from microseconds to centimeters (rounds to nearest cm).
+//   sonar.ping_timer(function [, max_cm_distance]) - Send a ping and call function to test if ping is complete. [max_cm_distance] allows you to optionally set a new max distance.
+//   sonar.check_timer() - Check if ping has returned within the set distance limit.
+//   NewPing::timer_us(frequency, function) - Call function every frequency microseconds.
+//   NewPing::timer_ms(frequency, function) - Call function every frequency milliseconds.
+//   NewPing::timer_stop() - Stop the timer.
+//
+// HISTORY:
+// 07/30/2016 v1.8 - Added support for non-AVR microcontrollers. For non-AVR
+//   microcontrollers, advanced ping_timer() timer methods are disabled due to
+//   inconsistencies or no support at all between platforms. However, standard
+//   ping methods are all supported. Added new optional variable to ping(),
+//   ping_in(), ping_cm(), ping_median(), and ping_timer() methods which allows
+//   you to set a new maximum distance for each ping. Added support for the
+//   ATmega16, ATmega32 and ATmega8535 microcontrollers. Changed convert_cm()
+//   and convert_in() methods to static members. You can now call them without
+//   an object. For example: cm = NewPing::convert_cm(distance);
+//
+// 09/29/2015 v1.7 - Removed support for the Arduino Due and Zero because
+//   they're both 3.3 volt boards and are not 5 volt tolerant while the HC-SR04
+//   is a 5 volt sensor.  Also, the Due and Zero don't support pin manipulation
+//   compatibility via port registers which can be done (see the Teensy 3.2).
+//
+// 06/17/2014 v1.6 - Corrected delay between pings when using ping_median()
+//   method. Added support for the URM37 sensor (must change URM37_ENABLED from
+//   false to true). Added support for Arduino microcontrollers like the $20
+//   32 bit ARM Cortex-M4 based Teensy 3.2. Added automatic support for the
+//   Atmel ATtiny family of microcontrollers. Added timer support for the
+//   ATmega8 microcontroller. Rounding disabled by default, reduces compiled
+//   code size (can be turned on with ROUNDING_ENABLED switch). Added
+//   TIMER_ENABLED switch to get around compile-time "__vector_7" errors when
+//   using the Tone library, or you can use the toneAC, NewTone or
+//   TimerFreeTone libraries: https://bitbucket.org/teckel12/arduino-toneac/
+//   Other speed and compiled size optimizations.
+//
+// 08/15/2012 v1.5 - Added ping_median() method which does a user specified
+//   number of pings (default=5) and returns the median ping in microseconds
+//   (out of range pings ignored). This is a very effective digital filter.
+//   Optimized for smaller compiled size (even smaller than sketches that
+//   don't use a library).
+//
+// 07/14/2012 v1.4 - Added support for the Parallax PING)))� sensor. Interface
+//   with all but the SRF06 sensor using only one Arduino pin. You can also
+//   interface with the SRF06 using one pin if you install a 0.1uf capacitor
+//   on the trigger and echo pins of the sensor then tie the trigger pin to
+//   the Arduino pin (doesn't work with Teensy). To use the same Arduino pin
+//   for trigger and echo, specify the same pin for both values. Various bug
+//   fixes.
+//
+// 06/08/2012 v1.3 - Big feature addition, event-driven ping! Uses Timer2
+//   interrupt, so be mindful of PWM or timing conflicts messing with Timer2
+//   may cause (namely PWM on pins 3 & 11 on Arduino, PWM on pins 9 and 10 on
+//   Mega, and Tone library). Simple to use timer interrupt functions you can
+//   use in your sketches totally unrelated to ultrasonic sensors (don't use if
+//   you're also using NewPing's ping_timer because both use Timer2 interrupts).
+//   Loop counting ping method deleted in favor of timing ping method after
+//   inconsistent results kept surfacing with the loop timing ping method.
+//   Conversion to cm and inches now rounds to the nearest cm or inch. Code
+//   optimized to save program space and fixed a couple minor bugs here and
+//   there. Many new comments added as well as line spacing to group code
+//   sections for better source readability.
+//
+// 05/25/2012 v1.2 - Lots of code clean-up thanks to Arduino Forum members.
+//   Rebuilt the ping timing code from scratch, ditched the pulseIn code as it
+//   doesn't give correct results (at least with ping sensors). The NewPing
+//   library is now VERY accurate and the code was simplified as a bonus.
+//   Smaller and faster code as well. Fixed some issues with very close ping
+//   results when converting to inches. All functions now return 0 only when
+//   there's no ping echo (out of range) and a positive value for a successful
+//   ping. This can effectively be used to detect if something is out of range
+//   or in-range and at what distance. Now compatible with Arduino 0023.
+//
+// 05/16/2012 v1.1 - Changed all I/O functions to use low-level port registers
+//   for ultra-fast and lean code (saves from 174 to 394 bytes). Tested on both
+//   the Arduino Uno and Teensy 2.0 but should work on all Arduino-based
+//   platforms because it calls standard functions to retrieve port registers
+//   and bit masks. Also made a couple minor fixes to defines.
+//
+// 05/15/2012 v1.0 - Initial release.

+// This example shows how to use NewPing's ping_timer method which uses the Timer2 interrupt to get the
+// ping time. The advantage of using this method over the standard ping method is that it permits a more
+// event-driven sketch which allows you to appear to do two things at once. An example would be to ping
+// an ultrasonic sensor for a possible collision while at the same time navigating. This allows a
+// properly developed sketch to multitask. Be aware that because the ping_timer method uses Timer2,
+// other features or libraries that also use Timer2 would be effected. For example, the PWM function on
+// pins 3 & 11 on Arduino Uno (pins 9 and 11 on Arduino Mega) and the Tone library. Note, only the PWM
+// functionality of the pins is lost (as they use Timer2 to do PWM), the pins are still available to use.
+// NOTE: For Teensy/Leonardo (ATmega32U4) the library uses Timer4 instead of Timer2.
