Some TFT libraries support a "uint16_t readPixel(uint16_t x , uint16_t y )" function aimed at returning the color of the pixel at location (x,y).
I appreciate that not all TFT controllers or shields support 2 ways communication so such a function may not always work but when it does work, it would be a great help on some programs.
Is there any chance to have this function added to the TFT_ILI9341 library?
