Other Parts Discussed in Thread: DLPC900

hello：

I have some questions. If we want to design exposure machine , we may have a lot of pictures . Through the pattern model to control it. we choose the vedio pattern. I want to ask is this pattern appropriate? Another question i want  to ask so many pictures how to transfer them. The space of flash is not enough.If we want to through vedio pattern,how to set a image to a vedio.

    Hi,

    Video Pattern can be used when there are many pictures to be displayed.

    You can follow below guidelines  -

    1. Video Timing - Refer to the video timing specification given in the DLPC900 datasheet. Decide what frame-rate you can send the 24-bit pixel data.

    2. Understand how you want the DLPC900 to process in the input 24-bit pixel data. Based on the available time (1/frame-rate) decide which bits and time of exposure of bit(s). Note always make sure the total sum of pattern(s) exposure in 24-bit pixel data is <= 1/frame-rate

    3. Pack the each pattern bit(s) into the 24-bit pixel as per the processing order selected in step #2 above. Once packed you can send the data like any other video frame with timing strictly as per the guidelines in DLPC900 datasheet.

    Regards,
