Hardware Detail
The J822 Development Kit hardware is extremely simple and is intended to illustrate the ease of use of
the Color Management Controller. The development board features the following hardware elements:
COLOR MANAGEMENT CONTROLLER AND SYSTEM CONTROLLER
The board is incorporated with two processors, one is the HDJD-J822 color management controller and
the other is the Microchip PIC18F252 system controller.
DISPLAY
Eight Side-Emitting RGB Light Emitting Diodes (LED) are connected to emit colored light to a 3.5 inch
lightguide. This lightguide has micro-dot printed on the bottom side which lights up the whole lightguide,
causing it to glow in color (depending on what color setting is input to the color management controller.
One green LED is provided to determine whether there is power to the development board (LED on) or
not (LED off).
POWER SUPPLY
The development board has a switching regulator that will step-down the 12V input to provide +5V
supply needed to power up all the components onboard plus driving the eight LEDs. An external 12V,
1000mA or more unregulated DC supply can be plugged into J1.
Note: The J822 Development Kit does not include a power supply.
PARALLEL PORT
A parallel port interface is provided for easy interfacing with an IBM-PC computer. The port is used to
emulate I
2
C communication using software to perform the communication translation job. Since no
special hardware is needed on the parallel port side, hence normal 25-way to 25-way parallel port cable
can be used to hook up the board with the computer.
On the IBM-PC computer side, the BIOS -> Onboard Peripheral -> Parallel Port setting must be set to
Output-Only or Standard mode, before you can run the demonstration PC software (included in the
CD-ROM).
LED DRIVER
LX1991 LED drivers (U5-U10), from Microsemi, are included on the board to illustrate a typical LED
driving method. User can choose to use their own LED driver circuit to drive their LEDs through the use
PWM output pins on the external input-output connector.
The data sheet of this LX1991 LED driver is included in the CD-ROM for user reference.

SWITCHES
Seven switches provide the following functions:
• PB1 – Active-high switch connected to Pin 9 (COLOR) of HDJD-J822
• PB2 – Active-high switch connected to Pin 10 (BRIGHT) of HDJD-J822
• PB3 – MCLR to hard reset the PIC18F252 system controller
• PB4 – Active-high switch connected to Pin 4 (RA2) of PIC18F252 system controller
• PB5 – Active-high switch connected to Pin 5 (RA3) of PIC18F252 system controller
• PB6 – Active-high switch connected to Pin 6 (RA4) of PIC18F252 microcontroller
• PB7 – Active-high switch connected to Pin 7 (RA5) of PIC18F252 microcontroller
* By default, 4 different color points will be programmed for PB4-7 for quick demonstration
purpose.
When pressed, the switches are pulled high (+5V) (except for PB3, which is grounded). When idle, they
are grounded (except for PB3, which is pulled high +5V).
SENSOR INPUT
For J822 Development Board, it supports RGB color sensor input. A 3-pin header is provided for this
purpose. Besides that, the development board also included a RGB color sensor module, located on top of
the display panel, for feedback color management demonstration. HDJD-S822 color sensor is used on the
development board.
The S2 DIP switch is used to set the gain of the individual R,G and B channel of the color sensor used on
the development board. Each channel gain is selectable through a 2-bit gain selector.
• S2-1 – Green Gain-1
• S2-2 – Red Gain-1
• S2-3 – Green Gain-0
• S2-4 – Red Gain-0
• S2-5 – Blue Gain-1
• S2-6 – Blue Gain-0
For user information, this S2 gain switch is sensor dependent. Different sensor has different gain setup.
The data sheet for this sensor is included in the CD-ROM for your reference.
SERIAL EEPROM
A M24C01 1K (128 x 8) serial EEPROM, from STMicroelectronics, is included on the board to illustrate
I
2
C bus concepts and to store HDJD-J822 calibration data.
6
IN-CIRCUIT SERIAL PROGRAMMING (ICSP) CONNECTOR
By way of the header connector (CON1), the PIC18F252 system controller can be connected for onboard
reprogramming. The ICSP connector utilizes RB6 and RB7 of the system controller for in-circuit serial
programming. This connector is compatible with Microchip Promate 2 programmer, which support ICSP
interface.
ADC INPUT LOW-PASS FILTER
Since the LEDs are controlled by pulse width modulation output from the HDJD-J822, the sensor output
will also be pulse width modulated. Each sensor channel needs to be averaged by passing the sensor
output voltage through a low pass filter. On the board, this low pass filter is realized through a RC low-
pass filter (R11/C5, R12/C7 and R13/C8).
Further explanation on the resistor and capacitor selection is documented in the application note, which
is included in the CD-ROM.
OSCILLATOR OPTIONS
There are two oscillator onboard the development kit. One is for the HDJD-J822 color management
controller and the other is for the PIC18F252 system controller. For HDJD-J822, an RC oscillator
(2.5 MHz approximately) is supplied. The operating frequency of HDJD-J822 can be changed by changing
the ROSC resistor value (R2).
For PIC18F252 system controller, a crystal oscillator (10 MHz) is supplied. If user would like to operate
the onboard system controller at different frequency, this crystal oscillator (Y1) can be changed to other
value.
EXTERNAL INPUT-OUTPUT CONNECTOR
Most of the HDJD-J822 color management controller and HDJD-S722 color sensor pins are mappable on
the external input-output connector. These pins include:
•PWM output R/G/B (PWM R/G/B)
•I

• Error flag (ERR-FLAG)
• Bright control (BRIGHT)
