Hello Tom, could you explain me how XDMD does the grayscale or colour handling of bitmap images ? Background of my question: I'm trying to create some static Real DMD Images for my PinDMD v2 with Vishay. I use GIMP 2.8, with a canvas of 128x32 and have defined a palette with 8 gray levels between 0% and 100% My problem is, that values below 50% all seems to be too bright on the Vishay. Anything between 5% and 50% looks the same. What I'm doing wrong ? Thanks a lot for some more information.
