4.3. CP210x USB to UART VCP Driver Installation
The Target Board includes a Silicon Labs CP210x USB-to-UART Bridge Controller. Device drivers for the CP210x
need to be installed before the PC software can communicate with the MCU through the UART interface.
1. After opening Simplicity Studio for the first time, a dialog will prompt to install the CP210x drivers. Click
Yes. The drivers can also be installed at any time by going to Help
Install DriversCP210x VCP USB
Drivers.
2. Accept the license agreement and follow the steps to install the driver on the system. The installer will let
you know when your system is up to date. The driver files included in this installation have been certified by
Microsoft.
3. To complete the installation process, connect the included USB cable between the host computer and the
USB connector (P4) on the Target Board. Windows will automatically finish the driver installation.
Information windows will pop up from the taskbar to show the installation progress.
4. If needed, the driver files can be uninstalled by selecting Windows Driver Package—Silicon
Laboratories... option in the Programs and Features window.
4.4. Configuration Wizard 2
The Configuration Wizard 2 is a code generation tool for all of the Silicon Laboratories devices. Code is generated
through the use of dialog boxes for each of the device's peripherals.
Figure 3. Configuration Wizard 2 Utility
The Configuration Wizard 2 utility helps accelerate development by automatically generating initialization source
code to configure and enable the on-chip resources needed by most design projects. In just a few steps, the wizard
creates complete startup code for a specific Silicon Laboratories MCU. The program is configurable to provide the
output in C or assembly. For more information, please refer to the Configuration Wizard 2 help available under the
Help menu in Config Wizard 2.
