USB-2-I2C
Conversion Kit for HDJD-JD13
Operating Hardware Manual
Introduction
The USB-2-I2C kit is a simple conversion board, which
allows USB connectivity for existing Illumination & Color
Management (ICM) development kit that uses parallel
port interface to connect to an IBM-PC computer. This
conversion board doesn’t need any new USB driver to
work since the driver is come pre-installed in Windows
2000/XP operating system.
The USB-2-I2C conversion kit comes with the following:

USB-2-I2C Conversion Board
The USB-2-I2C conversion board has the following hard-
ware features:
1. USB port and associated hardware for direct connec-
tion to an IBM-PC computer USB port
2. 5V to 3.3V voltage level shifter IC
3. Micrcontroller for USB to I2C data transfer
4. Jumper to select either using USB +5V or external
+5V
5. PCB mounting socket for external +5V supply
6. PWM Flex connector that connects to external LED
driver
7. HDJD-JD04 Flex Connector that connect the HDJD-
JD04 exible circuit board
8. PWM header pin that connects to external LED
driver
9. General purpose external I/O connector to connect to
the unused I/O port of the onboard microcontroller
10. I2C interface that connects to existing ICM develop-
ment kits that needs USB connectivity. This interface
connects to a parallel port conversion cable.

USB Port
A USB port interface is to provided for easy interfacing
with an IBM-PC computer. The port is used to emulate
I2C communication, using the onboard microcontroller
as the protocol translator. Normal type-B USB cable is
used to hook up the board with the computer.
Onboard I2C Voltage Level Shifter
An onboard voltage level shifter, Philips P82B96, is pro-
vided to allow the board to work with dierent I2C bus
voltage.
External Input-Output Connector
Various ports are provided to allow easy interfacing with
additional peripherals (not included with this kit). These
ports include :
PWM output in header pin and ex-cable connector
(J3/4)
External I/O pin (J5) for user development purpose
HDJD-JD04 ex-cable connector (J2) for interfacing
with ADJD-J823 ex-cable version
Hardware Detail
The USB-2-I2C Conversion Kit hardware is extremely
simple to use and is intended to help user by providing
a tool for user to convert the parallel port based develop-
ment kit into USB compatible port.
Power Supply
The conversion board is designed to run without any sort
of power supply by harnessing the power from the PC
USB port (+5V). The power port is provided on the board
in case user would like to use an external power supply if
the power requirement is more than 500mA. JP1 is used
to switch between these two form of supply source.
I2C port for parallel cable convertor
This port is hook up with the parallel cable convertor
(included in the kit) to allow user to interface with Avago
Technologies ICM development kit that uses parallel port
interface.
In-Circuit Serial Programming (ICSP) Connector
By way of the header connector (J9), the PIC18LF2455
protocol translator microcontroller can be connected
for onboard reprogramming. The ICSP connector utilizes
RB6 and RB7 of the microcontrller for in-circuit serial pro-
gramming. This connector is compatible with Microchip
Promate 2 programmer or ICD-2 in-circuit debugger,
which support ICSP interface.

Using USB-2-I2C Conversion Kit (using HDJD-JD13)
The following image illustrates how the conversion
board is connected with Avago Technologies HDJD-JD13
ICM evaluation kit.
Since the parallel conversion cable doesn’t have power
pin, power supply is needed to power up HDJD-JD13 ICM
Evaluation Kit. Make sure the jumper JP1 on USB-2-I2C
conversion board is set to 5VUSB.
Connect the USB cable to an IBM-PC computer USB port.
Once the cable is connected, 2 LED indicators on the
USB-2-I2C should be lighted up. The power indicator will
light up rst follow by the enumeration indicator (usu-
ally after 1-2 seconds). When both indicators light up, it
means the USB enumeration on the PC is complete and
the board is ready to use with the CMS software (v1.5.0).
For instruction on how to use CMS software, please refer
to the software guide document that comes with the
CMS software installation program. The document is ac-
cesible through the Start Menu -> Program -> CMS 1.5.0
-> Software Guide.
