Other Parts Discussed in Thread: DLPC350

Hi

Whether the setting procedure of exposure time has changed in the FW version 3.0?

In our system, we have set the DLPC350 via I2C.
When the FW version 1.1 was possible to change the exposure time via I2C.
However, we don't change the exposure time via I2C only has updated the FW version 3.0.

Regards,

Masa

    We have changed the lsb to msb ordering to match with USB. Refer to the Readme_DLPR350PROM.txt file description that you can access after installing the v3.0 firmware.

    Specific details.

    - DLPC350 I2C Control mode - the commands listed below have been corrected to process in LSB to MSB order to match to USB command processing. Earlier firmware build commands are processed from MSB to LSB:
    * Retrieve Firmware Version - 0x11
    * Display Curtain Control - 0x06
    * Internal Test Patterns Color Control - 0x1A
    * Image Load Timing - 0x61
    * Retrieve Image Resolution info - 0x62
    * Color Space Conversion - 0x26
    * PWM Setup - 0x41
    * PWM Capture Configuration - 0x43
    * PWM Capture Read - 0x4E
    * Input Display Resolution - 0x07E
    * Trigger In1 Control - 0x79

    Hi Masa-san,

    Sure, we are actually in the process of updating both UG and PG to reflect the v3.0 changes. Once we are done we will post on the web.
