SAMPLE PROGRAMS

The J822 Development Kit includes a CD-ROM with sample demonstration system controller program.
This program can be used with the included HDJD-J822 color management controller and PIC18F252
microcontroller. Demo source code and compiled code (one Hex file) are provided.

J822 DEVELOPMENT KIT HARDWARE USER GUIDE

This guide describes the J822 Development Board, including hardware component layout  and schematic.
Tutorial and demonstration software user guide may be found in the kit programming code example
document, which are included in the CD-ROM. Detailed information on HDJD-J822 color management
controller and the onboard PIC18F252 system controller can be found in the device’s respective data
sheet.

Chapter 1 : Introduction -  This chapter introduces the J822 Development Kit and provides a brief
