Producertask ex2

We will create a task that will pull the temperature value then send it to the BUS.

First we will create a task using the dune_create_task script. Execute the following command

DH> python programs/scripts/dune-create-task.py . DuneAuthor Tutorials/TempProd

This will create TempProd task. Open the DH>src/Tutorials/TempProd/Task.cpp and write the following code.

#include <DUNE/DUNE.hpp>

namespace Tutorials
{
  namespace TempProd
  {
    using DUNE_NAMESPACES;

    struct Task: public DUNE::Tasks::Periodic
    {
      // Parameters.
      double m_temp;

      Task(const std::string& name, Tasks::Context& ctx):
        DUNE::Tasks::Periodic(name, ctx)
      {
        param("Temperature", m_temp)
        .description("Temperature to produce")
        .defaultValue("25.0");
      }
      void
      onEntityReservation(void)
      {
        inf("Starting: %s", resolveEntity(getEntityId()).c_str());
      }


      void
      task(void)
      {
        IMC::Temperature temperature;
        temperature.setSourceEntity(getEntityId());
        temperature.value = m_temp;
        dispatch(temperature);
      }
    };
  }
}
