1. Follow the steps to copy the driver files to the desired location. The default directory is
C:\Silabs\MCU\CP210x
.
2. The final window will give an option to install the driver on the target system. Select the “Launch the CP210x
VCP Driver Installer” option if you are ready to install the driver.
3. If selected, the driver installer will now launch, providing an option to specify the driver installation location. After
pressing the “Install” button, the installer will search your system for copies of previously installed CP210x
Virtual COM Port drivers. It will let you know when your system is up to date. The driver files included in this
installation have been certified by Microsoft.
4. If the “Launch the CP210x VCP Driver Installer” option was not selected in step 3, the installer can be found in
the location specified in step 2, by default
C:\Silabs\MCU\CP210x\Windows_2K_XP_S2K3_Vista
. At this
location run
CP210xVCPInstaller.exe
.
5. To complete the installation process, connect the included USB cable between the host computer and the USB
connector (P3) on the C8051F930 Target Board. Windows will automatically finish the driver installation.
Information windows will pop up from the taskbar to show the installation progress.
6. If needed, the driver files can be uninstalled by selecting “Silicon Laboratories CP210x USB to UART Bridge
(Driver Removal)” option in the “Add or Remove Programs” window.
3.3. Silicon Laboratories IDE
The Silicon Laboratories IDE integrates a source-code editor, a source-level debugger, and an in-system Flash
programmer. See Section 5. "Using the Keil Software 8051 Tools with the Silicon Laboratories IDE‚" on page 10 for
detailed information on how to use the IDE. The Keil Evaluation Toolset includes a compiler, linker, and assembler
and easily integrates into the IDE. The use of third-party compilers and assemblers is also supported.
3.3.1. IDE System Requirements
The Silicon Laboratories IDE requirements:
Pentium-class host PC running Microsoft Windows 2000 or newer
One available USB port
64 MB RAM and 40 MB free HD space recommended
3.3.2. 3rd Party Toolsets
The Silicon Laboratories IDE has native support for many 8051 compilers. The full list of natively supported tools is
as follows:
Keil
IAR
Raisonance
Tasking
Hi-Tech
SDCC
The demo applications for the C8051F930 target board are written to work with the Keil and SDCC toolsets.
3.4. Keil Evaluation Toolset
3.4.1. Keil Assembler and Linker
The Keil demonstration toolset assembler and linker place no restrictions on code size.
3.4.2. Keil Evaluation C51 C Compiler
The evaluation version of the C51 compiler is the same as the full version with the following limitations: (1)
Maximum 4 kB code generation, (2) There is no floating point library included. When installed from the CD-ROM,
the C51 compiler is initially limited to a code size of 2 kB, and programs start at code address 0x0800. Refer to
“AN104: Integrating Keil Tools into the Silicon Labs IDE" for instructions to change the limitation to 4 kB and have
the programs start at code address 0x0000.
