PS controller synchronization

autobot-2 · January 4, 2012, 10:29pm

Hi Jim,

I was following your tutorial on how to synchronize the Lynxmotion wireless playstation controller and ran in to a problem. I am using the Bot Board II. I have a brand new 9V battery powering the board. The results are only FF 255. The receiver and controller red LEDs blink. The green LED on the receiver is solid on. Included is a pic of the setup and my code.

Thank you for your help!
