If you want to mess around with your Xbox 360 controllers on a computer Microsoft would be pleased to sell you a USB dongle to do so. but [Tino] went a different route. The board that drives the Xbox 360’s status light ring also includes the RF module that wirelessly connects the controllers. He wired this up to his Raspberry Pi using the GPIO header.
The module connects through an internal cable television and is treated much like a USB device by the Xbox motherboard. The problem is that it won’t actually deal with the 5V rail found on a USB connector; it wants 3.3V. but this is no problem for the RPi’s pin header. once a few connections have been made the lights are controlled through SPI I2C and [Tino] posted some example code up on Github to work with the RF module. He plans to post a follow-up that interfaces the module with a easy microcontroller rather than an RPi board. If you can’t wait for that we’re sure you can figure out the details you need by digging through his example code.
