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
