How to Use?
Tiger City IMX Industrial Computer with Linux OS 

 Tiger computer is provided with some basic software examples that can be used as a starting point for developing custom programs. 

 The examples are available in: 

 

 C 

 Python 

 Bash 

 

 The examples are divided into categories: 

 

 External Interfaces 

 Internal Devices‎ 

 Front Panel‎ 

 TCX www 

 

 C examples 

 Examples written in C can be built with CMake. Put your source files into one folder and specify its name (${SRC_DIR} dir_name). Then create a CMakeLists.txt file in the parent directory (an example of this file is provided below). 

 CMakeLists.txt 

 In the parent directory create a new folder named "build" and enter it: 

 mkdir build && cd build 

 Next, configure your project using: 

 cmake .. 

 Then build your project with: 

 cmake --build . 

 After that, executable files should appear in the same folder. 

 ./file_name 

 Python examples 

 In order to execute Python files, go to the desired directory and type: 

 python3 file_name.py 

 Bash examples 

 In order to execute Bash files, go to the desired directory and type: 

 bash file_name.sh
