Some questions about sn65dsi86

Other Parts Discussed in Thread: SN65DSI86

Our hardware connection is MSM(mcu) + sn65dsi86 + LCD,there are some questions about sn65dsi86 as follows

1.Need we enable all the interrupt sources?
2.Most of the interrupt soucres are related to error.Should we re-send the display datas to sn65dis86 after reading the interrupt status register through I2C bus when INT occure?

    Hello,
    No, your software can enable each interrupt sources according to your needs . You may want to use the error reporting registers that the system software can read to help with system debug.
    Are you referring to the CSR register? Yes, it is possible to configure(write/read) all the I2C registers when the DSIX6 is passing the video stream provided on the DSI interface to the DisplayPort interface.

    HI Joel,

    Thanks for your reply.We have some new questions as follows:

    1.For example,firstly we enabled the IRQ_HPD of sn65dsi86，and the mcu sended the display datas to sn65dsi86,sencondly,we removed the LCD,the sn65dsi86 could occure an interrupt event,it was possible that some display datas missed.From resovling this problem,should the mcu re-send the display datas after detecting IRQ_HPD ?

    2.Do you have sample code of sn65dsi86?if yes ,could you share us?we want to clarify the control flow.

    BR,
