I’m not solving this.
The link http://seeedstudio.com/wiki/File:TFT%26TouchScreen_libraries.zip is not a valid link. There are no files there. So I went with http://seeedstudio.com/wiki/images/2/29/Tft_touch_libraries_11252011.zip, which has TFT and TouchScreen files. I deleted ALL files in my Arduino folder and just added the two files, but the TouchScreen file does not display in the Arduino program after restarting, and the TFT sketch will come up with lots of errors when verifying.
I also tried downloading the files at https://github.com/adafruit/Touch-Screen-Library, which contains Touch_Screen_Library_Master. This has an example called Touchscreendemo which works in that it will display data on the Serial Monitor, but only the pressure changes. X = 1023 Y = 0 Pressure = 249. There is no display.
