I want to write something about k8055 board.
i try about 100 diferent I/O interface boards in my life . 3 months ago i find k8055 and i buy 4 boards
its the only interface that when i remove the usb from the pc nothing stack and when i put it back it continues to work perfect without any error , i attach and reattach the usb with a relay i make to find outif or when the k8055 will stack . the answer:NEVER … after 108.000 cycles (10 days of attach and reattach every 8 seconds) the board works like before. just perfect
wow finally someone(velleman) make the perfect interface
i use this code for automatic connection
