Hi. I'm looking for an example of how to hook up and program a lynxmotion PS2 controller without using the BotBoard. I have a Universal Development Board for the Atom Pro40 I am using for a Dev board rather than a BotBoard, but all the examples I can find to program the PS2 controller are for the BotBoards.
My DevBoard
http://www.basicmicro.com/USB-Universal ... _p_69.htmlNote: I've already tried using the code from the BotBoard I and II examples and just plugging the controller straight to the proper ports on the Atom Pro, but I couldn't get it to work. The code I'm using is shown below, and is from an example I found online. When it runs, it outputs all 0's in the terminal. I'm pretty sure the receiver and controller are powered properly. When it first turns on, the green light is solid and the red light is blinking on the receiver. Then when I turn the controller on, the red light on the receiver goes solid. But like I said, I'm still having trouble getting the controller to output correctly, and I didn't know if it was because the code I was using was for a BotBoard II or something. My connections are to the proper pins, including a 10k pullup resistor on the DAT line. Any ideas on what the problem could be? Thanks!
Code:

CMD con P5

CLK con P7

; we don't care about reading the data from the controller here.
; so, why not use this to read PS2 data the first time? because it's not working:
; as the PS2 controller is starting to send data just after receiving the

; and as we are sending after that some data for motors "... ,$0\8,temp(7)\8,temp(8)\8]"
; it's now too late to read all the data from the PS2 controller
; because there's already some bytes sent by it and lost (no buffer here).
