 # YKUSH Command Application
 
 
-Control application for Yepkit YKUSH Switchable USB Hub board.
+Control application for Yepkit YKUSH Switchable USB Hub boards.
 
 
 Description
 ===========
 
-Console application developed to illustrate the programmatic control of YKUSH capabilities.
+Console application developed to illustrate the programmatic control of YKUSH family boards capabilities.
 It executes one command per run, being appropriate to be executed as a console command.
 But it can be easily adapted to execute a work-flow with multiple commands and we encourage you to alter it to best fit your needs.
 
-The core of the application is consolidated in two source code files, the *commandParser.cpp* and the *usbcom.cpp*.
-The first contains the work-flow control and the second the communication functions.
+The implementation makes use of libusb for Linux builds and hidapi for Windows.
+For Linux we include a build and installation script, `build.sh` and `install.sh` respectively, for building and installing the application. 
 
-The implementation makes use of hidapi open-source library which is portable across several operating systems.
-We include a Visual Studio solution file for building on Windows. For Linux we include a build and installation script, `build.sh` and `install.sh` respectively, for building and installing the application. 
 
-Note that hidapi is not included in the source code package and has to be obtained beforehand. For Linux, if the
-`build.sh` script is used, to build the application, it will take care of downloading and building the hidapi library for you. In Windows this step has to
-be manually performed by the user.

 Building
 ========
 
-The steps for building on Windows and Linux are detailed bellow.
-
-Windows
--------
-
-Before building the application from source on Windows you need to get the [hidapi library](http://www.signal11.us/oss/hidapi/) and build it.
-Follow the instructions in the hidapi documentation for building the library in the several systems. 
-
-After building the hidapi library you need to include the relevant hidapi files to *ykushcmd* project. 
-
-Copy to `ykush\ykushcmd\windows\` the following hidapi library files:
-- hidapi.dll
-- hidapi.exp
-- hidapi.lib
-
-
-Open the `ykush\ykush.sln` with Microsoft Visual Studio and build the solution.
-After a successful build process the executable file will be created in the`ykush\bin\` folder.
-
-The next step is to make the dynamically linked library accessible to executable.
-We can install the `hidapi.dll` in the system or ensure that a copy of the file is in the same folder than the `ykush.exe`.
+The steps for building on Linux and Windows are detailed bellow.
 
 
 Linux
 -----
 
-The easiest way to build the application on Linux is to use the `build.sh` script which is in the `ykush/` folder.
-Nonetheless the application can be built running make and using the provided Makefile directly, but it will require
-some prior manual configuration detailed ahead. 
-
-To build the application using the scripts run the following inside the `ykush/` folder.
+For Linux `libusb-1.0` must be installed. For Debian based systems run the following.
 ```
-./build.sh
+sudo apt-get install libusb-1.0-0 libusb-1.0-0-dev
 ```
-Note that the script requires Internet connectivity to fetch the latest version of hidapi library.
-
-Some dependencies may not have been satisfied and some additional systems components and utilities may be required.
-If that was the case please install them and re-run the script. 
-
-After a successful build process you can install the ykush command in the system. To do so, in `ykush/` folder run:
+With these dependencies installed, build the application the running the following script.
 ```
-sudo ./install.sh
+./build.sh
 ```
 
-After install, the `ykush` command is ready for use.
-
-
-On the other hand, if you want to build running make directly with the provided Makefile do the following.
-
-First get the [hidapi library](http://www.signal11.us/oss/hidapi/) and build it.
-Please follow the instructions in the hidapi documentation for building the library in the several systems. 
-
-After building the hidapi library include the relevant hidapi files to *ykushcmd* project. 
-
-Copy to `ykush/ykushcmd/linux/` the `libhidapi-hidraw.so` and the `libhidapi-libusb.so` files from hidapi library you
-just built.
-
-Now add the following lines to the `platformdefs.h` file which is in the `ykush/ykushcmd/` folder.
+After a successful build process you can install the ykush command in the system. To do so, run:
 ```
-#ifndef PLATFORMDEFS_H
-#define PLATFORMDEFS_H
-#define LINUX
-#endif
+sudo ./install.sh
 ```
 
+After install, the `ykushcmd` command is ready for use.
 
-Next, in the `ykush/` folder run `make` to build the application.
-If the build process is successful the ykush executable will be created in the `ykush/bin/` folder.
-
-The next step is to make the shared library accessible to the executable.
-Do this by installing the *libhidapi-hidraw.so* or the *libhidapi-libusb.so*, depending if the hidraw or the libusb back-end is to be used (in doubt install both), in a system folder (e.g., /usr/lib/) or set the environment variable *LD_LIBRARY_PATH* with the path to the library files. 
-Alternatively you can run the script `install.sh` which is located in the `ykush/` folder.
 
 
-Using it
-========
-
 Windows
 -------
-Navigate to the `ykush\bin\` folder and run `ykush.exe -h` to print all the available command options a syntax.
 
-Let's look at some command examples.
+To build using MinGW run the following command.
 
-Assuming that just one YKUSH board is connected to our host, if we wanted to turn **OFF** the downstream port 1 we would issue the following command.
+For 32bit:
 ```
-ykushcmd.exe -d 1
+make -f Makefile_win32
 ```
 
-Similarly, if we wanted to turn the downstream 1 back **ON** we would issue the following command.
+For 64bit:
 ```
-ykushcmd.exe -u 1
+make -f Makefile_win64
 ```
 
-Assuming that two YKUSH boards are connected to our host and we wanted to turn **OFF** the downstream port 1 of one specific board. 
-To accomplish this we need to address the command by the YKUSH board **serial number**. 
-To find out the boards serial number we can issue the following command.
-```
-ykushcmd.exe -l
-```
-This will print the serial number of all YKUSH boards attached to the host.
-Assuming the our board had the serial number YK1234567, we would issue the following command.
-```
-ykushcmd.exe -s YK1234567 -d 1
-```
-This would turn **OFF** the downstream port 1 of the board with the serial number YK12345.
+After a successful build process the executable file will be created in the `bin\Win32` or `bin\Win64` folder depending if it was the 32 or 64 bit build.
 
 
-Linux
------
-For Linux the command options and syntax are the same with the slight difference that the executable file does not have the `.exe` extension.
-Also depending of your user permissions you may need to precede the command with the *sudo* directive (e.g, `sudo ykushcmd -d 1`).
+
+Using it
+========
+
+For details on using YKUSHCMD please refer to the [YKUSHCMD Reference Manual](https://www.learn.yepkit.com/reference/ykushcmd-reference-ykush/1/2).
 
 
-For more information and resources for the YKUSH board please visit the [yepkit website ykush page](https://www.yepkit.com/products/ykush).

+		<p>
+			YKUSH3 boards have an I2C interface alowing them to be connected to a
+			I2C bus and communicate to other devices in that bus.
+			The board can be configured in I2C slave mode, for other I2C devices to be
+			able to control the switching of the downstream ports, or in master mode
+			to be able to control other I2C devices.
+		</p>
+		<p>
+			To configure the board to operate I2C in slave mode and be controlable
+			by a master I2C device the user must enable the 
+			<i>i2C control interface</i> feature.
+		</p>
+		<p>
+			When the board is configure with I2C in master mode it provides a
+			USB to I2C gateway funcionality.
+			With this USB to I2C gateway functionality a user can communicate with
+			a slave I2C device, connected in the same I2C bus than YKUSH3 board,
+			from the command line of the PC using <i>ykushcmd</i> application.

- * Description:
- *
- * 	All commands in the cmd array are send to the YKUSH board and the
- * 	response bytes are stored in the matching resp entry. If more than
- * 	one YKUSH board is connected to the host it will send the command

- *
- * 	If there are more than one YKUSH board connected to the same host
- * 	the commandBySerial function should be used instead.
- *
- * Inputs:
- *
- *	iSerial	-	Serial number of the YKUSH board to issue the command.
- *	cmds	-	Command bytes to be sent to YKUSH.
- *	resp	-	Array for storing response bytes
- *	num	-	Number of entries in cmds and resp
- *
- * Outputs:
- *
- * 	The function will return the response byte or zero.
