My dearest friends,
I am connection a 1778 controller to a 7 inch (800x480) TFT module. How much memory will be needed for a TFT like this? Please help.
Hard to say, but enough that you can decently remember the important parts of the datasheet for the display, the datasheet for the processor, the assignment and the programming language standard.
Or did you mean RAM for storing image information? That would depend on what graphical mode the display is running under, and if you need to cache multiple pages of pre-drawn information.
At a 16-bit colour depth figure 750KB, at 24-bit 1125KB
