1. libusb 1.0.9 (or higher) is required for compilation and functioning of the APIs in the library.

2. GNU Make, the GCC toolchain, and CMake are used for the build process.

1. Make a build directory and cd to it. Example: mkdir build && cd build

2. Run cmake on the source directory and then make. Example: cmake ../ && make

3. Run sudo make install to install the header file, libraries, and test utility into PREFIX (/usr/local/ by default).

4. If you're on Linux, you might need to run ldconfig now.

5. You can now launch the application and communication with the Cypress USB-Serial DVK in vendor mode.

Refer to the CyUSBSerial API documentation for descriptions of all the vendor mode APIs. The header file of the library is in ./include/CyUSBSerial.h.
