4.2. Silicon Labs IDE

The Silicon Labs IDE integrates a source-code editor, source-level debugger and in-system programmer. The

following sections discuss how to open an example project in the IDE, build the source code, and download it to the

target device.

4.2.1. Running the CP250x_NoScreen example program

The CP250x_NoScreen example program drags a simulated finger starting from the top left corner of the screen

towards the middle of the screen and releases.

1. Open the Silicon Labs IDE from the Start menu.

2. Select ProjectOpen Project to open an existing project.

3. Browse to the C:\SiLabs\MCU\Examples\CP250x\NoScreen directory (default) and select the

CP250x_NoScreen.wsp project file and click Open.

4. Once the project is open, build the project by clicking on the Build/Make Project button in the toolbar or

selecting ProjectBuild/Make Project from the menu.

Note: After the project has been built the first time, the Build/Make Project command will only build the

files that have been changed since the previous build. To rebuild all files and project dependencies, click

on the Rebuild All button in the toolbar or select ProjectRebuild All from the menu.

5. Before connecting to the target device, several connection options may need to be set. Open the Connec-

tion Options window by selecting OptionsConnection Options... in the IDE menu. First, select the

“USB Debug Adapter” option. Next, the correct “Debug Interface” must be selected. CP2501 devices use

Silicon Labs “C2” 2-wire debug interface. Once all the selections are made, click the OK button to close the

window.

6. Click the Connect button in the toolbar or select DebugConnect from the menu to connect to the

device.

7. Download the project to the target by clicking the Download Code button in the toolbar.

Note: To enable automatic downloading if the program build is successful select Enable automatic con-

nect/download after build in the ProjectTarget Build Configuration dialog. If errors occur during the

build process, the IDE will not attempt the download.

8. Click on the Go button (green circle) in the toolbar or by selecting DebugGo from the menu to start run-

ning the firmware.

9. Connect the USB connector on the daughter board to a Windows Vista or Windows 7 PC that supports HID

touchscreens.

10. The device will enumerate and then drag the simulated finger across the screen.

4.2.2. Creating a New Project

Use the following steps to create a new project. Once steps 1-5 in this section are complete, continue at Step 4 in

Section 4.2.1.

1. Select ProjectNew Project to open a new project and reset all configuration settings to default.

2. Select FileNew File to open an editor window. Create your source file(s) and save the file(s) with a rec-

ognized extension, such as .c, .h, or .asm, to enable color syntax highlighting.

3. Right-click on “New Project” in the Project Window. Select Add files to project. Select files in the file

browser and click Open. Continue adding files until all project files have been added.

4. For each of the files in the Project Window that you want assembled, compiled and linked into the target

build, right-click on the file name and select Add file to build. Each file will be assembled or compiled as

appropriate (based on file extension) and linked into the build of the absolute object file.

Note: If a project contains a large number of files, the “Group” feature of the IDE can be used to organize.

Right-click on “New Project” in the Project Window. Select Add Groups to project. Add pre-defined

groups or add customized groups. Right-click on the group name and choose Add file to group. Select

files to be added. Continue adding files until all project files have been added.

5. Save the project when finished with the debug session to preserve the current target build configuration,

editor settings and the location of all open debug views. To save the project, select ProjectSave Project

As... from the menu. Create a new name for the project and click on Save.
