DLP4710EVM-LC: lnternal Patterns的Pattern的.bin文件无法保存

Part Number: DLP4710EVM-LC
Other Parts Discussed in Thread: DLPC3479

当使用 lnternal Patterns 进行加载Pattern的.bin文件时,出现如下图所示的错误,导致无法加载;

同时进行保存的时候也会出现类似这个的警告 Pattern's timings are not validated before saving to file.但文件可以成功保存在选择的文件夹中

求大佬进行解答

  • 可能是曝光时间设置不对,请参考论坛置顶的FAQ第14个问题,计算对应的曝光参数。时序表请参考FAQ第21条。

    另外DLPC3479的最大曝光参数计算公式如下:

      • Notes:
        • For internal patterns, there will be an additional variable delay of ~3000 us at the beginning of every pattern set.
        • Exposure times shorter than the above values are not possible. Longer exposure times will operate with decreased timing accuracy and behavior is not guaranteed.
        • Shorter dark times are not possible. Longer dark times can be used. The maximum possible dark times for a desired exposure time are:
          • Tmax pre-exposure dark time  = ( 27306us + tsequence min pre-exposure dark time ) * (Tdesired exposure / tsequence minimum exposure)
          • Tmax post-exposure dark time = ( 27306us + tsequence min post-exposure dark time ) * (Tdesired exposure / tsequence minimum exposure)
