DLP3010EVM-LC: Minimum board specification that can operate Internal Pattern Streaming Mode.

Part Number: DLP3010EVM-LC
Other Parts Discussed in Thread: DLPC3478

We are currently considering the miniaturization of the board based on the DLP3010EVM-LC.

We plan to use only Internal Pattern Streaming Mode as the operation mode of DLPC3478.

Is my understanding correct that only the following board parts in the figure are required to operate Internal Pattern Streaming Mode?

*Assuming that the projector is started immediately after connecting the AC adapter.

*The PROJ_ON signal is fixed to high level voltage after connecting the AC adapter.

-DLP3010

-DLPC3478 with Flash 32Mb

-DLPA2005

-USB-Serial Bridge Controller(CY7C65215)

-Trigger input/output pin

-VLED output connector

-DMD Flex Cable connector

-USB connector

-19V DC jack

In other words, are the following board parts in the figure unnecessary?

-MSP430

-IT6801 with EEPROM

-DAC

-Push Buttons

-SW_ONOFF

-HDMI connector

-AUDIO connector

Also, does the GUI tool (DLP Pico Display and Light Control EVM) not recognize the projector board if the specific Vendor ID and Product ID are not written in the IC of the USB-Serial Bridge Controller?

Ultimately, we will make these decisions at our own risk.

Regards,

Yuta

    Yuta-san,

    Please refer to figure 33 on page 52 of DLPC3478 datasheet. This figure is a simplified block diagram for "Internal pattern Mode".

    https://www.ti.com/lit/ds/symlink/dlpc3478.pdf

    I would suggest that you include a simple micro-controller in the board. It can be used for managing the system and user interface. It can send I2C command to the DLPC3478 controller to drive the system.

    If you intent to to use GUI with your board, you need not add the "USB to serial bridge controller" chip. You can use GUI with external Devasys board (connected to I2C pins on board) to control your system. The only challenge will the firmware upgrade on flash will be considerably slow (through I2C) and may have plan for external programming of flash.

    You wrote -

     "Also, does the GUI tool (DLP Pico Display and Light Control EVM) not recognize the projector board if the specific Vendor ID and Product ID are not written in the IC of the USB-Serial Bridge Controller?"

    The GUI uses the SDKs provided by Cypress to detect the USB-Serial Bridge Controllers. Cypress SDK may require the chip to have specific VID and PID. The GUI does not do any such checks.

    Hope this answers your question.
