How to make changes to source code?

Linux Operating System

• Open the source codes by browsing to this location : OpenModelicaEmbedded > Source.
• After making changes to these files open Terminal.
• Browse to OpenModelicaEmbedded > Source folder using cd command.
• Run command make.

Windows Operating System

• Open the source codes by browsing to this location : OpenModelicaEmbedded > Source.
• After making changes to these files open Command Prompt (cmd).
• Browse to OpenModelicaEmbedded > Source folder using cd command.
• To compile the CPP files run the command: g++ -c modelPlugFirmata.cpp serial.cpp.
• To create a DLL from generated object files, run the command: g++ -shared -o modelPlugFirmata.dll modelPlugFirmata.o serial.o.
• Then copy the generated DLL file and paste it in folders: OpenModelicaEmbedded and Resources > Library > win64.

Working with Arduino UNO [Atmega328p]

Setting up firmware for Arduino board

• In Tools Menu, select appropriate Board (Arduino/Genuino UNO) and Port as the available serial port to which Arduino is connected.
• Open pidmata3 sketch: File > Open > OpenModelicaEmbedded > Firmware > Arduino > pidmata3 > pidmata3.ino.
• Upload the sketch to the board.

Simulating the Modelica model

• Now open OMEdit window.
• Open package.mo file OpenModelicaEmbedded folder.
• In OpenModelicaEmbedded package, open ArduinoExamples package which consists of examples for arduino board.
• Check and simulate the example models and verify the results.

Working with Tiva C [TM4C123G]

Simulate a model with Tiva C

• In Energia, open the firmware for Tiva C provided in folder through path : File > Open > OpenModelicaEmbedded > Firmware > Tiva C > StandardFirmata > StandardFirmata.ino or add zip file of this StandardFirmata as an external library in Energia from the same folder.
• Select appropriate Board (Tiva C) and Port (USB port where Tiva C is connected) in Tools menu.
• Then, upload the firmware on board.
• Now open OMEdit and Open the package.mo file from OpenModelicaEmbedded package
• Open an example provided in the OpenModelicaEmbedded package which includes a Tiva C board.
• Check and Simulate the model and verify the results in Plotting window.
