How to use?

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:

C examples

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

CMakeLists.txt

cmake_minimum_required(VERSION 3.10)
project(examples)

function(link_gpiod target)
    target_include_directories(${target} PRIVATE ${GPIOD_INCLUDE_DIRS})
    target_link_libraries(${target} PRIVATE ${GPIOD_LIBRARIES})

link_gpiod(DIP_Read)

In the parent directory create a new folder named build,build and enter itit:

and
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 simplyfiles, go to the desired directory and type:

python3 file_name.py

Bash examples

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

bash file_name.sh
