DLPC3479: Program&load 1D patterns

Part Number: DLPC3479

I would like to know a mechanism for programing&loading 1D patterns.

In GUI, Light Control > Internal Patterns > Pattern Set Order > 4. Program the Flash.

Regarding #4 process, is my below understanding correct?

1. The patterns as #3 process(Define pattern set display order and configuration) are written to a flash via Cypress-SPI.

2.The command as "98h:Write Pattern Order Table Entry" is sent to DLPC via Cypress-I2C.

3. The patterns saved in flash are loaded to DLPC RAM.

  • Hello Uryyy,

    Are you using the latest version of the GUI available at www.ti.com/.../dlpdlc-gui The steps that should be followed are labeled #1 - #7 with help buttons also on the page.

    To actually program the flash overall your process sounds correct. A series of commands are sent to the Cypress over USB which are then sent via SPI to the flash and to the DLPC347x as I2C commands as needed. The patterns are loaded into the DLPC347x before display. The command log under "Debug" will show what commands are sent to the controller.

    Thanks,
    Kyle

    Hi Kyle,
    Yes, I have already downloaded&Installed&used above GUI. If it is only loading patterns from flash which has already saved patterns, I could understood by myself that GUI operation should start from "Pattern Control".
    Thank you.
