Writing EEROS Applications for Beaglebone Blue Board

Back to Use on a Beaglebone Blue Board.

You will use C++ to develop your EEROS applications. For this you need at least some knowledge of the basic language features. A good starting point might be https://www.cplusplus.com/doc/tutorial/. Minimal help can also be found under C++ for Beginners.

What do you want to do next?

Say Hello with EEROS

  1. Fetch the EEROS scripts on your host and checkout the branch for the Beaglebone Blue
    $ git clone https://github.com/eeros-project/eeros-build-scripts.git eeros-project
    $ cd eeros-project
    $ git checkout sdk_bbb
  2. Edit the file config.sh.in as follows
    custom_application_name=hello
  3. Create a project directory and change into it with
    $ mkdir hello
    $ cd hello 
  4. Create a text file “main.cpp” and copy the following code into it
    #include <iostream>
    #include <eeros/logger/Logger.hpp>
    #include <eeros/logger/StreamLogWriter.hpp>
     
    int main() {
      using namespace eeros::logger;
     
      Logger::setDefaultStreamLogger(std::cout);
      Logger log = Logger::getLogger();
     
      log.info() << "Hello, EEROS";
     
      return 0;
    }
  5. Create a text file “CMakeLists.txt” and copy the following text into it:
    cmake_minimum_required(VERSION 3.5.1)
    project(helloworld)
     
    set(CMAKE_CXX_STANDARD 14)
     
    find_package(EEROS REQUIRED)
    include_directories(${EEROS_INCLUDE_DIR})
    link_directories(${EEROS_LIB_DIR})
     
    add_executable(helloworld main.cpp)
    target_link_libraries(helloworld eeros ucl ${CMAKE_DL_LIBS})
  6. Change back into your parent directory and build the project with
    $ cd ..
    $ ./make.sh
  7. Make changes to “main.cpp”, save them and rebuild with
    $ ./make.sh

    In order to be able to write your own EEROS programs, you could use any text editor. However, we recommend to use an integrated development environment, see Use KDevelop with Existing Build Configuration.

Continue with Deploy to Beaglebone Blue Board.

Use Existing Project

As an example we use the Control a Single Motor demo program.

  1. Fetch the EEROS scripts on your host and checkout the branch for the Beaglebone Blue
    $ git clone https://github.com/eeros-project/eeros-build-scripts.git eeros-project
    $ cd eeros-project
    $ git checkout sdk_bbb
  2. Edit the file config.sh.in as follows
    custom_application=simple-motor-control
  3. Fetch the code of the application with
    $ ./clone.sh
  4. Build the project with
    $ ./make.sh

Continue with Deploy to Beaglebone Blue Board.
