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.
