2.4 The Usage of Embest IDE

2.4.1 Embest IDE Main Window

To step into Embest IDE for ARM, just run Embest IDE.exe. Embest IDE user interface consists of an integrated set of windows, tools, menus, directories, and other elements that allow you to create, test, and debug your applications. The main window of Embest IDE is shown in Figure 2-26. The Embest IDE main Window includes Title Bar, Menu Bar (1), Tools Bar (2), Project Management Window (3), Data Watch Window (4), Status Bar (5), Memory Window (6), Output Window (7), Variable Window (8), Stack Window (9), Register Window (10) and Source Code Window (11).

2.4.2 Project Management

1. An Introduction to the Project Manager

The project is an important concept for Embest IDE. It is a basic architecture for users to organize source files, set compile and linking options, generate debug information, and finally generate the BIN file for the target processor. The Embest IDE project management functions include:

(1) File management in a Project Management Window (Figure2-27).

(2)Provides dialogs for microprocessor/debug device selection and settings, configuration of debug information, compiler/assembly/linker settings, etc.

(3)Provides Build menu and tool buttons and output build information the Build page in Output Window (Figure 2-28).

2. Create a Project

A workspace consists of one or multiple projects. The steps of creating a project are the followings:

(1)Select FileÆ New Workspace, IDE will prompt a dialog for creating a new project. The dialog box is shown in Figure 2-29.

(2)Fill in the project name, use the default directory or select another directory for saving the project.

(3)Click OK. A new project will be created. A new workspace with the same name as the project’s name will also be created. Also for an existing workspace new projects can be added by right clicking the workspace name in the Project Management Window.

3. Create New Source File

Select FileÆ New, IDE will open a new edit window without a title. The user can input and edit source code in this window and save it.

4. Add Files to Project

Select ProjectÆAdd To ProjectÆFiles or right click the project name bar in the Project Management Window and the IDE will open a new dialog box for file selection. This is shown in Figure 2-30.

5. Set Active Project

If there are more than one project in the workspace, the user can activate any of these projects by right clicking the project and select “Set as Active Project”. This is shown in Figure 2-31.

2. Emulator Settings

54

Embedded Systems Development and Labs; The English Edition

Select ProjectÆSettings… The IDE will open a new dialog box. Select the “Remote” page shown in

Figure 2-33.

Figure 2-33 Emulator Connection Settings Dialog

If the software emulator is used, the “Simarm7” should be selected. If Power ICE is used, the “PowerIceArm7” should be selected. If a parallel port cable is used in connecting PC and ICE, “Parallel Port” should be selected. Only the emulator supported download speed is valid when you select the download speed for emulators. Power ICE for ARM supports all speeds.

3. Debugging Settings

The debug related settings are shown in Figure 2-35. There are the following three options: 1) General

●Download file: Symbol file name and its directory. Symbol file includes debug information. Normally symbol file is an elf format file or a coff format file.

●Action after connected: There are three ways for selection:

¾None -- No actions after the IDE connected to target.

¾Auto download – After the IDE is connected to the target, the file will be automatically downloaded to the board.

¾Command script -- After the IDE is connected to the target, a script file will be executed first.

2) Download Settings

Download settings page is shown in Figure 2-36.

●Download file: Symbol file name and its directory. Symbol file includes debug information. Normally the symbol file is an elf format file or a binary file. When download as an elf file the system will automatically convert it into a binary file.

●Download verification: Automatically compare the downloaded file if it is the same as the original file.

●Download address: The downloaded file will be stored from this address.

●Execute program from:

¾Don’t care – After download the system’s PC (program counter) will not change.

¾Download address – After download the system will execute from this address.

56

¾Program entry point -- After download, the system will set the PC to the program entry point.

●Execute until: The last symbol the system will execute after the download.
