Control application for Yepkit YKUSH Switchable USB Hub board.
Console application developed to illustrate the programmatic control of YKUSH 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 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,
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.
The source code is licensed under MIT license. Refer to LICENSE file.
The steps for building on Windows and Linux are detailed bellow.
Before building the application from source on Windows you need to get the hidapi library 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.
ykush\ykushcmd\windows\ the following hidapi library files:
ykush\ykush.sln with Microsoft Visual Studio and build the solution.
After a successful build process the executable file will be created in the
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
The easiest way to build the application on Linux is to use the
build.sh script which is in the
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
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:
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 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.
libhidapi-hidraw.so and the
libhidapi-libusb.so files from hidapi library you
Now add the following lines to the
platformdefs.h file which is in the
#ifndef PLATFORMDEFS_H #define PLATFORMDEFS_H #define LINUX #endif
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
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
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.
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.
ykushcmd.exe -d 1
Similarly, if we wanted to turn the downstream 1 back ON we would issue the following command.
ykushcmd.exe -u 1
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.
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.
For Linux the command options and syntax are the same with the slight difference that the executable file does not have the
Also depending of your user permissions you may need to precede the command with the sudo directive (e.g,
sudo ykushcmd -d 1).
