Eclipse : New Project & Tricks

The easiest way to create a new project in Eclipse is:

• Copy and paste the folder of a sample project.
• Rename the folder that you copied to your new project name.
• In Eclipse, go to File -> Import
• Click on General -> Existing Projects into Workspace
• Hit Next -> Browse and find your copied folder
• Click Finish

Create New Project

At minimum, you need a Linker file (loader.ld) and a specific startup file for a new project. You can copy loader.ld and cr_startup_lpc175x.cpp from the sample project into your new project. To create a new project, follow the steps below:

• Go to File -> New -> C++ Project
• Under ARM Cross Target Application click on Empty Project
• On the right side, choose ARM Windows GCC (Yagarto)
• Click Finish

Development Package uses Yagarto toolchain

Configure Project Settings

After you create a new project, you've still got several settings to configure!

• Right click on your project and go to Properties
• Browse to C/C++ Build --> Settings
• Click on Target Processor on the right side and select cortex-m3
• Click on Debugging and change the Debug level to none
• Click on ARM Yagarto Windows GCC Compiler --> Directories

  Include the directories of your project

  This is so that you will have to #include file's absolute path

  Repeat the same thing for ARM Yagarto Windows GCC C++ Compiler

• Click on ARM Yagarto Windows GCC C++ Compiler --> Miscellaneous

  Put check-mark on Do not use exceptions

  Put check-mark on Do not use RTTI

• You may want to turn on optimizations to Os

  C Optimizations are at ARM Yagarto Windows GCC Compiler --> Optimizations

  C++ Optimizations are at ARM Yagarto Windows GCC C++ Compiler --> Optimizations

Select Processor Type

Most important project settings involve linker/loader file:

• Go to ARM Yagarto Windows GCC C++ Linker
  • Click on General and if your loader.ld file is at project root, type in ../loader.ld next to Script file (-T)
  • Put check-mark on Do not use standard start files
