Avago USB-2-I2C Operating Manual

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 (Figure 1-1) • Parallel port conversion cable • USB cable • USB-2-I2C Conversion Kit Operating Hardware Man- ual • CMS Program (V1.5.0) for communicating with HDJD- J822 • CMS Program (V2.1.0) for communicating with ADJD- J823 If you are missing any part of the kit, please contact your nearest Avago Technologies sales office listed in the back of this publication for help. 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 flexible 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. 11. In-circuit programming port for microcontroller

Figure 3. Parallel Convertor 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 different 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 flex-cable connector (J3/4) • External I/O pin (J5) for user development purpose • HDJD-JD04 flex-cable connector (J2) for interfacing with ADJD-J823 flex-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.

Figure 5. Disconnect state Figure 6. Connect and successful enumeration state USB Enumeration Indicator Power Indicator 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 first 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.
