1. Overview
The LCD Development Kits (CP2400-DK and CP2401-DK) provide all the hardware and software required to
develop and test LCD applications. The CP240x LCD Firmware Library is included to aid in the code development
process and handle the communication between the C8051F9xx MCU and the CP2400/1 LCD controller. The LCD
library can be used to communicate with the LCD controller through the SPI interface (CP2400-DK) or the SMBus
interface (CP2401-DK). Example code using the LCD library is included with both development kits.
The LCD development kit hardware includes a C8051F930 target board, CP2400 or CP2401 LCD Development
Board, USB Debug adapter, and an ac to dc power adapter. The C8051F930 Target Board features the 25 MIPS,
64 kB Flash, over 4 kB RAM, 8051-based C8051F930 MCU. The C8051F930 MCU is part of the low-power family
and can operate with a supply voltage from 0.9 to 3.6 V. The MCU LCD interface provided by the AB board
consists of the CP2400/1 LCD controller and an LCD and is compatible with the C8051F930-DK and C8051F912-
DK. The LCD development kit includes example code which uses either the SPI interface (CP2400-DK) or SMBus
interface (CP2401-DK) on the C8051F930 to control the LCD using the LCD library.
The Silicon Labs’ IDE supports full-speed, non-intrusive MCU debugging and is bundled with an evaluation version
of the Keil C51 Toolchain allowing immediate application code evaluation in C. Projects with up to 4 kB of object
code and unlimited library code can be developed using the included toolset. Numerous application code examples
are included in the development kit and a walkthrough of an LCD example is included in 6. "Example Source
Code‚" on page 11.

3. Software Overview
All software required to develop firmware and communicate with the target microcontroller is included in the CD-
ROM. The CD-ROM also includes other useful software.
Below is the software necessary for firmware development and communication with the target microcontroller:
Silicon Laboratories Integrated Development Environment (IDE)
Keil 8051 development tools (macro assembler, linker, evaluation C compiler)
Other useful software that is provided in the CD-ROM includes the following:
Configuration Wizard 2
Keil µVision drivers
CP210x USB to UART Virtual COM Port (VCP) drivers
3.1. Software Installation
The included CD-ROM contains the Silicon Laboratories Integrated Development Environment (IDE), Keil software
8051 tools and additional documentation. Insert the CD-ROM into your PC’s CD-ROM drive. An installer will
automatically launch, allowing you to install the IDE software or read documentation by clicking buttons on the
Installation Panel. If the installer does not automatically start when you insert the CD-ROM, run
autorun.exe
found
in the root directory of the CD-ROM. Refer to the
ReleaseNotes.txt
file on the CD-ROM for the latest information
regarding known problems and restrictions. After installing the software, see the following sections for information
regarding the software and running one of the demo applications.
3.2. CP210x USB to UART VCP Driver Installation
The C8051F930 Target Board includes a Silicon Laboratories CP2103 USB-to-UART Bridge Controller. Device
drivers for the CP2103 need to be installed before PC software such as HyperTerminal can communicate with the
target board over the USB connection. If the "Install CP210x Drivers" option was selected during installation, this
will launch a driver “unpacker” utility.

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.

3.5. 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 4. Configuration Wizard 2 Utility
The Configuration Wizard 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 language. For more information, refer to the Configuration Wizard documentation.
