View Full Version : Data from a PC's joystick

05-10-2006, 09:45 AM
Hey,·before I start messing around with·this I was wondering how I could interface a PC's joystick (old style DB15 pin)·to a BS2? I have pulled a few apart and after looking at them I noticed that all the pots and buttons inside·lead to a small circuit with an IC. Is that some kind of clock? I was reading this recent·post (http://forums.parallax.com/showthread.php?p=586257) about how a PS/2 mouse can be interfaced, seems that there’s an internal·clock in a mouse.·So would that·make it so I can’t use shiftin?·Can I get some kind of chip that can·convert the data? I don’t really·know what Game port/joystick data looks like or is even·called. But if its different then just straight pots connected to a BS2 I wouldn’t be able to use any type of pot scaling either?

im trying to send data (X,Y and the buttons) using serout·that then goes through a digital tranceivers to be received by·another basic stamp·that controlls two stepper motors that can·pan, tilt and zoom·a camera·and turn on or off a·spot light·(the video signal is·sent back by a·seperate transmitter)···

thanks for any help

You can read an old analog joystick directly -- see this article: http://www.parallax.com/dl/docs/cols/nv/vol2/col/nv70.pdf
