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.

CP2400/1-DK 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. - Page 6 CP2400/1-DK 3.6. Silicon Labs Battery Life Estimator The Battery Life Estimator is a system design tool for battery operated devices. It allows the user to select the type of battery they are using in the system and enter the supply current profile of their application. Using this information, it performs a simulation and provides an estimated system operating time.
- Page 7 CP2400/1-DK Figure 6. Battery Life Estimator Discharge Profile Editor The Discharge Profile Editor allows the user to modify the profile name and description. The four text entry boxes on the left hand side of the form allow the user to specify the amount of time the system spends in each power mode.

Keil µVision2 and µVision3 Silicon Laboratories Drivers As an alternative to the Silicon Laboratories IDE, the µVision debug driver allows the Keil µVision2 and µVision3 IDEs to communicate with Silicon Laboratories’ on-chip debug logic. In-system Flash memory programming integrated into the driver allows for rapid updating of target code.

Keil 8051 tools with the Silicon Laboratories IDE. To build an absolute object file using the Silicon Laboratories IDE project manager, you must first create a project. A project consists of a set of files, IDE configuration, debug views, and a target build configuration (list of files and tool configurations used as input to the assembler, compiler, and linker when building an output object file). -
Page 11: Example Source Code
CP2400/1-DK 6. Example Source Code Example source code and register definition files are provided in the “SiLabs\MCU\Examples\C8051F93x_92x\” default directory during IDE installation. These files may be used as a template for code development. Example applications include a blinking LED example which configures the green LED on the target board to blink at a fixed rate. - Page 12 CP2400/1-DK If using a CP2400, this line should say: #define BUS_INTERFACE 6.4.3. Example Selection The example that is run on the CP2400/1 LCD development board can be selected in the file, app_config.h. The available examples include a voltage display example, digit display example, and several current measurement examples.
