Came quickly, test progam works, touch and SD card not yet tested. Useful info: www.lcdwiki.com
After quite some effort, I managed to test the touch feature. I installed the XPT2046 library fort the touch - in addition to th Ucglib for the tft. Got wired behavior. Modified the XPT2046 a bit until calibration and getting the coordinates of atouched point worked. My test program then draws 5 circles and I do my best to follow these circles with the touch pen. As one can see from the foto, the result is not very nice. Obviously, one can only use the touch feature for touching rather big buttons on the screen. When the buttons are no big, one risks that the XPT2046 detects the touch of a wronf button.
ALL OK. works fine
