DLP2010LC: Is there any method to use only the chip internal memory without flash updating to update inernal pattern when DLPC works in internal streaming mode?

Hello Gavin,

Welcome to the E2E forum and thank you for your interest in DLP® technology.

Do you mean you want to use internal pattern mode without re-flashing the firmware image file? 

If yes, you can use DLPDLC-GUI. In the Light Control -> Internal Patterns pages, upload your internal patterns/pattern set and configure the display order and settings. then you have option to load the pattern data directly flash to run the patterns. For these steps, you do not need to re-build the image file and re-flashing it to the system. 

For more information about how to use the DLPDLC-GUI internal pattern pages, please refer to the DLP Display and Light Control EVM GUI Tool User Guide section 4.3.2.

Hi Lori,

Thanks for your reply.

I have already read the  DLP Display and Light Control EVM GUI Tool User Guide section 4.3.2. And I think the Flash Update Commands will be executed when the button "Program and Load Pattern" (in the EVM GUI Light Control -> Internal Pattern ->Program the Flash column) is pressed, is that right?

I do not mean I want to use internal pattern mode without re-flashing the firmware image file.

Actually I want to update the internal pattern data without using the Flash Update Command to update internal pattern data stored in SPI flash.

Since we may update pattern when our products have already been delivered to to customers, we do not want to update the internal pattern using the Flash Update Command as the dlpu075b  Section 3.7 (Flash Update Commands) shown.  There may be a risk of updating SPI flash when products have already been delivered to customers.

Is there any method to upload internal pattern data(prebuild pattern xxx.bin file) directly to the chip internal memory(not SPI flash)?  We only need to upload one pattern set(1 bit mode, less than 25 patterns) internal pattern data to chip internal memory since we think the chip internal memory may be large enough to store only one internal pattern set data.

Hi Lori,

    Thanks for your reply, I have known there is no such method, but I still think this is a useful requirement, espetially for meidical devices .

Hello Austin,

    If WRITE_DISPLAY_SIZE command can work with internal pattern mode(we have known this command can not work with internal pattern streaming mode now),  it will be helpful to avoid unwanted light noise for special cases, e.g. intral oral scan.

Hello Austin,

    Thanks for your help  so long, I'll be glad if you have any progress to tell me.

Hello Gavin, 

1. In the Light Control internal pattern mode, we do not support varying display sizes via Write Display Size command. Can you please share more information about your use-case in which you want to display patterns of a different size than the native DMD resolution? 

2. As Lori suggested, we do not have capability of programing the pattern data for internal pattern display directly into the ASIC IRAM without going through SPI flash.

Hello Mayank,

    Could you please accept my friend request? It will be convenient to tell our requirements in details.
