DS90UH949-Q1EVM: [DS90Ux949EVM] EDID external configuration

Part Number: DS90UH949-Q1EVM


Hi Ti experts,

I would like to configure EDID to external and I don't have the I2C table to set the relevant register.

Could you please provide me with the i2c table for setting EDID to external?

BR,

Ivan

    Hello Ivan,

    Please see datasheet sections 7.3.4 and 7.4.1 for details on EDID configuration, strapping, and registers.

    Best Regards,
    Casey

    Hi Casey,

    I would like to set external EDID by setting register.

    According datasheet, It seems like I need to configure some registers for external EDID. 

    Could you please provide me with that register table which I should set?

    Hello Ivan,

    The EDID SRAM can be accessed through the indirect registers in the APB section. See datasheet page 54.

    Register 48 sets the APB interface - in this case you would use EDID SRAM

    Registers 0x49 and 0x4A set the address of the EDID byte

    0x4B-0x4E show the data in the registers in 4 byte chunks. You can write these registers to change the EDID information.

    Best Regards,
    Casey
