fpga based on, touch screen panel with VHDL

Hi everyone!

Currently I am working on the project which involves the nios ii fpga embedded evaluation kit, cyclone iii editionboard. I am trying to develop the VHDL code for a FPGA based LCD touch screen controller with a simple interaction function like run or stop to control motor, Is there any VHDL code.

Any help regarding this matter is much appreciated especially VHDL

coding for touch screen interface.
