Hi,

Let me talk about Flip/Invert of DLPC350.

Does it Flash access when Flip and Invert ?
If yes, We have to pay attention about life time.

Hello Hiroyasu,

If you are loading the original image from flash, you are required to send the reload image command after the flip command. You should be able to find this information on page 24 of the DLPC350 programmers guide. Therefore, as a worse case scenerio you should consider each flip and invert also requiring access to flash.

Thanks,

Kyle

Hello Kyle

Thank you for your support again !

Sorry, In video mode it should be resent, but
it is not necessary to re-send in Structured Light mode.
I post this.

I want to confirm it is no Flash access in Structured Light mode when each flip and invert

Hello Hiroyasu,

I believe that is correct. The flip command itself shouldn't access the flash. It is only accessed if/when the next image is loaded from the flash. Therefore, no additional flash access is required.
