Hi, I'm trying to use the PS/2 port of the Arcade MegaWing using a Papilio One. Before diving into it headfirst, I thought I'd try some off-the-shelf code from someone who actually knows what he's doing, so I found a very simple PS/2 driver at http://soclab.cn.nctu.edu.tw/course/FPGA102/ps2_ctrl.pdf. The attached zipfile is a Xilinx ISE archive of my version of that code. All it tries to do is set LED3 to high after the first key is pressed. LED1 and LED2 are connected directly to the PS/2 Clock and Data ports. Before I even connect my keyboard (a Microsoft Natural 4000 via a USB-to-PS2 dongle) to the FPGA, LED1 and LED2 are already continuously on. After I connect it, both LEDs stay on, and if I press a key, LED3 doesn't turn on. I should also add that there's a LED on the keyboard itself that shows that the keyboard is definitely at least connected to the power pins. What am I doing wrong? ps2.zip
