Specifying a colormap

We have a DT024DTFT RGB screen. We are displaying data on-screen - is there a way to map specific colors to a specific value range (i.e., specify a colormap for the data?)

Hi,

We apologize for the delay.

Unfortunately, this driver does not have the capability to specify a color map. The display driver chip does have gamma correction, but this is not useful as a RGB color map tool. You will need to do this on the video source end. Usually, the microcontroller generating the video will use a lookup table to convert RGB data from one color map to another. Depending upon how much memory and processor speed you have, you might find it easier to modify the original images if they are just stored in memory somewhere.
