Because I work at the kernel 3.4. So I use the old version of fbtft. commit number is 06f0bba152c036455ae76d26e612ff0e70a83a82. But i find that when I use Qt to display a picture ,the picture is very small at the central of the screen. And the color is also wrong. I use spi to control, 16bpp and width,height is 240, 320. I just add st7789v in fbtft_device.c and dont change other code.I cant find the reason, wish you could help me,thank you very much.
