PS/2 KEYBOARD TEST APPLICATION These are the design files for a test application of the PS/2 keyboard interface that combines it with the LED digit to display numbers typed on the keyboard. You can find an application note on the keyboard interface at http://www.xess.com/appnotes/an-102104-keybrd.pdf. SOURCE FILES XSA_LIB/ps2_kbd.vhd: This file describes the PS/2 keyboard interface circuit. XSA_LIB/common.vhd: Some functions and definitions useful in many applications are provided in this file. [50,100,200,3S1000]/test_kbd/test_kbd.vhd: This is the top-level file that combines the keyboard interface with a seven-segment LED driver to create the complete test application for the XSA-50, XSA-100, XSA-200 or XSA-3S1000 Board. [50,100,200,3S1000]/test_kbd/test_kbd.ucf: These are the pin assignments for mapping the keyboard test application to the XSA-50, XSA-100, XSA-200 or XSA-3S1000 Board. [50,100,200,3S1000]/test_kbd/test_kbd.npl: This project file tells WebPACK how to combine the source files to create the keyboard test application for the XSA-50, XSA-100, XSA-200 or XSA-3S1000 Board. [50,100,200,3S1000]/test_kbd/test_kbd.bit: This is a configuration bitstream that has already been generated for the XSA-50, XSA-100, XSA-200 or XSA-3S1000 Board based on the files listed above. COMPILING AND RUNNING THE KEYBOARD TEST APPLICATION 1. Open the project file for the keyboard test application by double-clicking the test_kbd.npl file for your particular model of XSA Board. All the compilation options can be set through the Project Navigator interface of WebPACK, and the generic parameters that affect the operation of the keyboard test application can be set in the test_kbd.vhd file. (The options for compiling a working application are already set in the files provided.) Then double-click the "Generate Programming File" icon in the Process pane and the bitstream will be generated. 2. The keyboard test application needs a specific clock frequency to operate correctly. For the XSA-50 and XSA-100 Boards, use GXSSETCLK to set the clock divisor to 2 so that a 50 MHz clock is available. Nothing needs to be done for the XSA-200 or XSA-3S1000 Boards since they have a fixed frequency 100 MHz oscillator. 3. Open the GXSLOAD downloading tool. Drag-and-drop the test_kbd.bit bitstream file generated in step #1 into the FPGA pane of the GXSLOAD window. Then click on the Load button to download this file to the FPGA on the XSA Board. 4. Connect a PS/2 keyboard to the keyboard/mouse port of the XSA Board. Press-and-release any of the digits '0' - '9' on the keyboard and the corresponding numeral will appear on the seven-segment LED. Pressing any other key will cause an 'E' to be displayed. AUTHOR Dave Vanden Bout, X Engineering Software Systems Corp. Send bug reports to bugs@xess.com.
