+ * makes use of the UART for timing purposes.  The principle of
+ * operation is described here:
+ * https://www.maximintegrated.com/en/app-notes/index.mvp/id/214
+ *
+ * It is important the you use a UART with CMOS/TTL level voltages
+ * (3.3v/5v) RX and TX lines.  DO NOT use standard RS232 level
+ * voltages, or you are going to have a bad day.
+ *
+ * In addition, a diode should be placed across the RX and

+ *
+ * -|
+ * U|
+ * A| TX---|<--+
+ * R|          |
+ * T| RX-------o--------o 1-wire data bus
+ * -|
+ *
+ * The diode on TX is a 1N4148 (cheap and common), with the cathode
+ * connected to TX, and the anode connected to RX and the rest of the
+ * 1-wire data line.

+Using Firmata board with mraa      {#firmata}
+=============================
+
+Mraa can use a Firmata board as a subplatform. This means one can access the
+native IO as well as the IO on a firmata compatible board
+
+### Supported Firmata boards ###
+
+- Genuino/Arduino 101 running either CustomFirmata or StandardFirmata
+- Other Arduino boards will likely work but are as of yet unsuported
+
+### Using the subplatform API ###
+
+Using the subplatform API is relatively simple, simply add '512', the platform
+offset to any IO calls. I2c 0 becomes I2c 512+0 etc... The API works from UPM
+or mraa in any of the bindings as long as you compiled mraa with -DFIRMATA=ON.
+Currently -DFIRMATA is not compatible with USBPLAT. Multiple subplatforms are
+not yet supported
+
+### Sending custom SYSSEX messages ###
+
+You can use the firmata API to send custom SYSEX messages.
+
+### CurieImu Plugin ###
+
+Using Customisable firmata we're able to use the onboard IMU to get data. This
+uses the public SYSEX firmata API from mraa and there is a UPM module that
+exposes this capability in a simple way. To use it your board needs to use
+CustomFirmata with the CurieIMU plugin
+
+### Limitations ###
+
+Only one instance of mraa (one process linking to mraa) can communicate to an
+firmata subplatform. This is a limitation due to only having one application
+using the Uart at once. In order to get around this a daemon type methodology
+has to be used. Technically you can mirror the TTY port from firmata but this
+is likely going to cause issues

+# Building mraa with imraa	{#buildingimraa}
+Imraa allows seamless communication between the Arduino101 and your mraa
+projects. Imraa will flash an arduino101 and allow automatic loading of the
+MRAA_GENERIC_FIRMATA subplatform to the first process that calls imraa_init
+(done through mraa_init automatically)
+
+## Build dependencies
+To build imraa, you'll need to build mraa with -DIMRAA=ON and all the normal
+dependencies for build mraa, see [Building mraa](./building.md).
+You'll also need the following:
+* [dfu-utils-cross](https://github.com/arduino/dfu-utils-cross) or dfu 0.8 (0.9
+  does not work well with the 101). Precompiled binaries can be found on
+  [here](https://github.com/01org/intel-arduino-tools)
+* [json-c](https://github.com/json-c/json-c): likely called libjson-c-dev or
+  json-c-devel
+* libudev: likely called libudev-dev or libudev-devel
+
+## Basic build steps
+This will build mraa with imraa for the local default path. To build mraa for
+the system add `-DCMAKE_INSTALL_PREFIX=/usr` to the cmake command before
+running it.
+
+```bash
+mkdir build
+cd build
+cmake -DIMRAA=ON -DFIRMATA=ON ..
+make
+```
+
+After you've built mraa you can install using `make install`.
+
+## Running Imraa
+
+Before being able to use mraa to program the Arduino101 you will need to run
+imraa to flash the sketch file onto the board. The sketch file that imraa will
+look for is located here: [Arduino101 Sketch](http://iotdk.intel.com/misc/ConfigurableFirmataCurieImu.ino.bin).
+Once downloaded the file needs to be renamed and moved to the where mraa was
+installed. This is dependant on whether you installed locally or for the
+system. The example below is for a locally installed copy. Note this sketch is
+using ConfigurableFirmata + the [CurieIMU plugin](https://github.com/intel-iot-devkit/FirmataCurieIMU).
+
+
+```bash
+$ mv ConfigurableFirmataCurieImu.ino.bin firmata101.ino.bin
+$ mv firmata101.ino.bin /usr/local/share/mraa
+```
+
+You will also need to move the imraa config so that imraa can find it.
+```bash
+$ mv mraa/imraa/imraa.conf /etc/
+```
+
+To flash the board run imraa and it will create the lockfile and flash the
+Arduino101. You may need root permissions or to add yourself to the uucp or
+modem group to access the device node (typically /dev/ttyACM0).
+```
+$ imraa
+```
+
+After this is successful you will be able to use mraa like normal, in the
+background mraa will handle talking to the arduino101 by creating
+/tmp/imraa.lock which imraa_init() will parse on startup.

+Mock platform   {#mock}
+=============
+
+Mocking capability allows libmraa user to work with the library without any real
+hardware available. Enabling this requires library recompilation with architecture
+override (see Building section below). When mock is enabled, library simulates
+actual HW operations at the backend so that for the application it looks
+like a usual board. Being implemented at the backend, the functionality is available
+in all language bindings libmraa supports.
+
+Board configuration
+-------------------
+
+This feature is yet in the experimental mode and not all functionality is available.
+Right now we simulate a single generic board with:
+* GPIO (without ISR)
+* ADC with 10 (std)/12 (max) bit resolution, which returns random values on read
+* Single I2C bus with one device at address 0x33 and 10 bytes of register space,
+which can be read or written in bytes or words (big-endian). Technically those
+registers are just an array of `uint8_t`, so you can treat them as 10 single-byte
+registers or 5 single-word ones or a mix thereof.
+
+We plan to develop it further and all [contributions](../CONTRIBUTING.md) are more than welcome.
+
+See the table below for pin layout and features
+
+| MRAA Number | Pin Name |            Notes                      |

+
+Building
+--------
+
+Generally all the building steps are the same as listed
+in the [main building guide](./building.md), you just need to set some specific
+CMake options.
+
+### Linux
+
+To build under Linux, follow standard instructions, just make sure to set
+the `-DBUILDARCH="MOCK"` CMake option.
+
+### Windows
+
+Mocking capability allows us to build and use libmraa under Windows. That helps
+if you e.g. don't want to leave your customary Windows-based Python IDE, but
+want to develop libmraa-based programs.
+
+Building Node.js bindings was not yet tested under Windows as MSYS2
+does not have a ready-made package. Java was not tested either.
+
+#### Prerequisites
+
+You'll need the following to build libmraa under Windows:
+
+* [MSYS2](http://mingw-w64.org/doku.php/download/msys2) basic installation
+* Several additional packages, install them by running
+
+  ```bash
+  pacman -S cmake base-devel gcc git
+  ```
+
+#### Compiling
+
+The procedure is conceptually the same as under Linux - you first need to run
+CMake with specific options to generate makefiles and then run make to build everything.
+
+* Run MSYS2 shell (not a MinGW one)
+* Clone the libmraa git repo (let's assume into `/home/test/mraa/mraa-src` dir)
+* Create a build directory outside of the clone one (let's say `/home/test/mraa/mraa-build`)
+* Run CMake, switching off unsupported options and enabling mock platform:
+
+  ```bash
+  cmake ../mraa-src/ -DBUILDARCH="MOCK" -DBUILDSWIGNODE=OFF -DENABLEEXAMPLES=OFF
+  ```
+
+* Make, install and test:
+
+  ```bash
+  make clean && make install && make test
+  ```
+
+  All tests should pass.
+
+**Note:** To have autocompletion in Python IDE, just point it to MSYS2's Python
+and make sure to specify any additional paths pointing to site-packages dir
+with mraa module if IDE requires that ("Interpreter Paths" in PyCharm).
+With the above settings the module will be installed into `/usr/local/lib/python2.7/site-packages`
+and the libmraa itself - into `/usr/local/bin`.

+UP Board   {#up}
+============
+
+UP Board is based on the Intel(R) Atom(TM) x5-Z83xx SoC (formerly Cherry Trail).
+It includes 2GB RAM, 16/32GB eMMC flash, 6 USB2.0 ports, 1 USB 3.0 OTG port,
+1 Gigabit Ethernet, HDMI and DSI Graphics ports, RTC and a 40-pin I/O header.
+The form-factor for the board is based on the Raspberry Pi 2, and can be used
+with many of the add-on HAT boards designed for the Raspberry Pi 2.
+
+Interface notes
+---------------
+
+**PWM** PWM frequency range is from 293 Hz to 6.4 MHz.  8-bit resolution is
+supported for duty-cycle adjustments, but this reduces for frequencies > 97.6kHz
+
+**I2C** 2 I2C channels support standard-mode (100kHz) and fast-mode (400kHz).
+Bus frequency can be selected in BIOS settings.  Note that, unlike Raspberry Pi,
+the I2C controller issues Repeated-START commands for combined transactions
+(e.g. a write-then-read transaction) which may not be supported by some I2C
+slave devices.  For such devices, it is advisable to use separate write and
+read transactions to ensure that Repeated-STARTs are not issued.
+
+**SPI** Bus frequencies up to 25MHz are supported, in steps which are less
+granular at higher speeds.  E.g. Available speeds include:
+ 25MHz, 12.5MHz, 8.33MHz, 6.25MHz, 5MHz, 4.167MHz, 3.571MHz, 3.125MHz, etc.
+Please be aware that speeds in between those steps will be rounded UP to the
+next nearest available speed, and capped at 25MHz.
+At the time of writing, only a single native chip-select is available (SPI CS0).
+
+**UART** 2 high-speed UARTs are available, supporting baud rates up to
+support baud rates between 300 and 3686400.  Hardware flow-control signals are
+not exposed, so software flow-control may be needed for rates above 115200.
+A console UART is also available but is not fully supported at this time.

+Pin Mapping
+-----------
+
+The GPIO numbering in the following pin mapping is based on the Raspberry Pi
+model 2 and B+ numbering scheme.

+mraaStub - JavaScript simulation and stubs for mraa
+====================
+
+This project enables simulation of a device which might be accessed via mraa.
+Currently this library supports I2c, SPI, and GPIO.  This project provides
+several benefits:
+
+1. Prevent crashes in nodejs applications using mraa on unsuported or
+   misconfigured hardware.
+2. Enable basic simulation of mraa-accessible devices for unit testing.
+
+## Examples
+
+The following example is based on an imaginary 'light bulb' device abstraction,
+which exposes a value of brightness over a mraa-provided interface.  Please see
+the `test/index.js` file for an example.
+
+## Installation
+
+You may install `mraaStub` from npm like this:
+
+```
+npm install mraaStub
+```
+
+Since we often switch between a mraaStub and the real mraa library, we
+suggest creating an `index.js` file inside a `lib/mraaSwitcher` folder.
+
+```js
+/* index.js - file for switching between mraa and mraaStub
+ */
+
+// Define the conditions under which the mraaStub should be loaded
+var platform = require('os').platform();
+var m;
+
+if (platform === 'win32') {
+    m = require('mraaStub');
+} else {
+    m = require('mraa');
+}
+
+module.exports = m;
+```
+
+You can add this to your project in its own `lib/mraaSwitcher/index.js` file
+and use `require('../mraaSwitcher')` everywhere!
