DLPDLCR2000EVM: Control Individual Micro-mirrors?

Krishna,

As this is a DLP display chipset, you may be limited in the functionality you are seeking. In particular, you will need to display your patterns as a video stream coming from the BeagleBone Black (or a similar host processor). You could also potentially program patterns to the flash of the system and display these patterns by toggling splash screens, but the flash is not large enough to hold more than a couple images. The DMD's mirror count is 1:1 with the native resolution of the controller (640x360) so you can control individual mirrors to some extent by controlling the video output of the BeagleBone properly. However, you will not be able to exercise direct control over the mirrors themselves in the manner you describe with this chipset. Video algorithms which are not separable from the video pipeline may cause small alterations in the output image at the granularity of the individual mirrors.

In order to achieve the greatest level of control possible over the DMD, you would need to employ one of our DLP sensing chipsets. The LightCrafter 4500, for example, provides this sort of control with custom pattern settings:

I hope this helps.
