Starting pattern sequence from HDMI on startup in FW 3.0.0

Jakob Wilm

Other Parts Discussed in Thread: DLPC350

Prior to firmware 3.0.0, the projector would start to display the configured pattern sequence after bootup.

With the new firmware, after every reboot, we need to use the GUI, click 'Validate Sequence' and 'Play', before the sequence actually start. This is very inconvenient because it requires us to have a USB connection to the projector, which we did not use to have.

Are we overlooking something here?

    Hi Jakob,

    Can you confirm that you've
    1. Setup, validated and played your pattern sequence
    2. Saved that solution to an .ini file
    3. Then you rebuilt the FW with that solution's .ini file and loaded that FW onto the LightCrafter4500?

    Once you perform these steps, you will need to disconnect the LightCrafter4500 from the PC, otherwise the GUI will automatically connect and hault the sequence. This would cause the behavior you are observing (i.e. having to validate and play the sequence again).

    Thanks,

    Hello Clinton,

    those are exactly the steps i did, yes. The sequence plays fine after validation.

    After reboot, the only thing I have to do is:

    * Open GUI

    * Click 'validate sequence'

    * Click 'play'

    As mentioned, my sequence uses patterns from external video source. Can you confirm that this works/does not work?

    Regards,

    Jakob

    Hello,

    it's more than a year now, but issue still persist.
    Does TI know this issue and planing to solve it or any workaround?
    Thank you.

    Hi Nik,

    Let me take a deeper look into this and see if I can get an answer for you. Are you having this same issue?

    Just to clarify - you'd like to be able to power up the LCr4500 and have it display a pattern with an external source automatically?

    Thanks,
    Paul

    Yes, correct.
    Now I have to connect LC4500 via USB each time after power it up and Validate and Start Patter Sequence.

    Thank you Nik. Due to the Thanksgiving Holiday, I won't be able to get back to you until next week but I'll try to get an answer for you on this.

    Hi Nik,

     

    I believe I was able to recreate your issue here. We will look into it a bit more and get back to you.

     

    Just to clarify you are using the HDMI input in pattern mode and completed all the following steps:

    1. Created your preferred pattern sequence (selecting the video port for pattern source)

    2. Validated the sequence

    3. Save the solution to create a new .ini file

    4. Build a new firmware file using the new .ini

    5. Upload the firmware

    6. Restarted the system

    Hi Danny,

    Yes, I did exactly as you described in 1-6.

    Thanks.

    Hi Nik,

    I have done some looking and it does appear the DLPC350 will not process the incoming video data if you directly go to 'pattern mode' w/ video source. I am current looking for a way we can tackle this issue. Does you system have another controller that could seen I2C commands to the DLPC350?

     

    Best,

    Thank you Danny,

    No we do not have additional controller (with I2C or USB) connected to LC4500. Initial idea was flash it with particular settings and simply turn it on and use it.
    Will it be possible in next f/w? Or we should consider to use additional controller?

    Hi Nik,

     

    I am currently reaching out to the team to see if this functionality will be implemented in the future, and I will update when I know more. The reason it is not current implemented is that difficult to know how long it will take to detect and lock to the video signal. Improper implementation of this can cause unpredictably delayed frames  in displayed data. For now you can try implementing the solution using additional controller. The programmer's guide shows what commands can be sent to the DLPC350. The two that I believe will be useful to you are:

     I hope that helps!

    Hi Danny,

    Do you have any updates from team  about implementing this functionality in future release?

    For now do you have any workaround/howto what should be used and how on a top of projector to start the pattern sequence? May be arduino like board? 

    Thank you.

    Hi Nik,

    At this point, we have no further updates on implementing this functionality.

    The best answer for a work-around would be to have a separate controller which can issue those I2C commands on start-up. Exactly which you choose will depend on your application - but Arduino, MSP430, etc. would likely work well. Unfortunately, as we haven't tried this here, I don't have any further recommendations for you.
