Dear all,
We recently purchased a Lightcrafter Evaluation Module from TI, and a Lightcrafter 4500 module from Wintech.
In our application, we want to project 4 monochrome 8-bit patterns in sequence, using internal flash memory. This can be easily achieved using the EVM lightcrafter by uploading 4 8-bit grayscale images to flash memory and projecting them in a loop at 120Hz.
However, we are experiencing difficulties obtaining the same result in the 4500 module... Apparently, only packed 24-bit images can be uploaded to flash memory, after which seperating the RGB color channels allows the successive projection of only 3 8-bit monochrome images.
We realize that it is possible to upload 4 of these 24-bit images and organizing our 1-2-3-4 pattern loop in the following way:
123 412 341 234
but then we found that the 120Hz displaying speed is compromised and the projected images suffer from partial distortion (at 120Hz, part of the following pattern is projected onto the previous etc.)
It does clearly say in the specifications that the 4500 module is able to 'project 8-bit image sequences at 120Hz', no? Could you assist us in finding out how to achieve this?
Thanks,
Sam
