1. Introduction
This user manual describes the OM13502 demo board. The board consists of a base
board, with a plugged in LPCXpresso board which contains the microcontroller to control
the display driver. The PCA2117 is a low-power Liquid Crystal Display (LCD) controller
and driver. It is specifically designed to drive LCD dot-matrix displays of 2-lines by 20
characters or 1-line by 40 characters with 5 × 8 dot format. In addition 200 icons can be
displayed. The chip contains a character generator and displays alphanumeric
characters. The PCA2117 features an internal charge pump with internal capacitors for
on-chip generation of the LCD driving voltage. To ensure an optimal and stable contrast
over the full temperature range, the PCA2117 offers a programmable temperature
compensation of the LCD supply voltage. The PCA2117 can be easily connected to a
microcontroller by either the two-line I²C-bus or a four-line bidirectional SPI-bus.
This board was developed in order to provide a low cost tool to engineers, wishing to
demonstrate and evaluate this LCD driver, and to get hands-on experience with writing
code for it. Code written using this board can serve as an example for the final
application. This enables rapid prototyping.
Features:
• Demonstrates PCA2117 LCD driver
• Features a vertical alignment (VA) COG display module with integrated backlight. It
was designed with Car Entertainment and Home Entertainment in mind
• Plugged in OM13035 LPCXpresso board with LPC1115 microcontroller
• 3 push buttons
• User modifiable firmware, In-System/In-Application Programming (ISP/IAP) via USB
• Power supply can be done either via USB or an external power supply. This can also
be used for external V
LCD
• Box contents:
− OM13502 base board (marked on the board)
− OM13035 LPCXpresso board
The 12NC of the OM13503 board is 9353 031 19598.
