This development board has been created to
demonstrate many of the capabilities of the
PIC18F97J94 processor family (specifically, the
PIC18F67J94 device), including:
• Direct LCD drive, using a 4-common LCD display
• Serial interfacing, using the SPI protocol to 

interface with an accelerometer and an IEEE 
802.15.4 radio

• Use of the CTMU (Charge-Time Measurement 

Unit) to perform capacitive touch sensing.

• Low-power operation, using a single 1.5V AA 

battery as a power source (in conjunction with 
voltage boosting chip)

• USB HID bootloader, allowing programming 

through a USB cable (without requiring a 
programmer)

In order to demonstrate the capabilities of the
demonstration board, a simple dancing game has been
developed. See 

.

A 4-common, 4-digit LCD display
(Lumex #LCD-S401M16KR) is being used to display
the score. The PIC18F67J94 can support up to
8-common displays, but 4-common is a very popular
configuration among LCD displays. The PIC18F67J94
also has the capability to drive many more segments,
but this provides a starting point for many LCD
applications.
Individual segments can be controlled using 

(see LCD-S401M16KR data sheet for bit explanations): 

The image below (

board with many of the main board components
indicated.
