Hello,

I used "TFT_readData" for reading the color data from rectangular screen. I always received 0xff.

I tested it in tftspi.c:

// Read color line
ret = read_data(0, _height/2, _width-1, _height/2, _width, line_rdbuf, 0);
printf("Receive: ");
for (int u=0; u<_width*3; u++)
printf("%02x ",line_rdbuf[u]);
printf("\n");

Can anyone help me?
