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.
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.
