Configuration of DSI to eDP bridge SN65DSI86

Other Parts Discussed in Thread: SN65DSI86

Hi,

I would like to configure the SN65DSI86 DSI to eDP bridge chip to drive a iPad3 Panel, resolution 2048x1536.

Can someone point me the register programming sequence? Do you have the example code?

Thanks & Best Regards,

KL

  • Hello KL,

    TI provides the "DSI tuner tool 2.0" that is useful to configure the registers for the DSI86, you need to capture the panel parameters provided by the manufacturer and the tool returns a register configuration file for your specific case.

    You can download the software from link below.

  • Hi Luis,

    Thank you for your support. I can control it now. Then I have another question for about PSR.

    1) May I know how to enable PSR function?

    2) Can I enable PSR function in Color bar is generating?

    Thanks & Best Regards,

  • Hello KL,

    The PSR function of the DSI86 is intended to save power in a system-Level,

    1) You can enable the PSR function using the PSR Registers described in the page 54 "Table 33. CSR Bit Field Definitions – PSR Registers" of the DSI86 specification here basically explains that if you set the PSR_EXIT_VIDEO to 1 the DSi86 will transmit the IDLE patterns and the VSTREAM_ENABLE bit will be set. and if you configure the PSR_TRAIN bit to 0 the PSR train will be Normal Mode (idle pattern).

    2) The PSR function is not intended to work with the Color Bar pattern generation,

    Please let me know is this post answers your question.

    Regards,

    Luis.
