Hi,
I used the DPP6401 controller and 0.45'' DMD display chip. I used the display system in the products checking. So, in this system, we need some fixed pattern, so, camera is used to capture the projector image. But this method has a problem: the images that captured by camera have some color bar, and is due to camera exposure.
So, I want to fix the DMD mirror to generate pattern, and driver the LED using DC, But I do not konwn how to fix the DMD mirror to generate the fixed pattern?
thank you!
