 ====== DIY Xbox 360 PC wireless receiver with MSP430 control ======
+//Germany 15.06.2013//
 ===== Abstract =====
 Xbox 360 wireless controller can be used with PC when special adapter is used.
@@ Line 5: / Line 6: @@
 Additional interface is used to initialize module LEDs and start sync process.
 One can create adapter for a fraction of cost using only several elements.

 ===== Description =====
+Required parts:
+  * Xbox360 RF board
+  * USB cable
+  * MCU
+  * LDO (3.3 [V])
+  * Capacitor/resistor for MCU
 Pinout of the RF board from top:

 Board must be powered by 3v3 so I decided to use LDO.
-Furthermore to start pairing process specific command must be sent. I have used MSP430G2231 for this task.
+Furthermore to start pairing process specific serial command must be sent. I have used MSP430G2231 for this task.
 MCU need reset pull-up resistor and decoupling capacitor.
 Pins 1 and 8 are connected to RF board.
+Pairing process starts few seconds after device is powered. No external button needed.

+===== Notes =====
+  * There is no way to detect if controller is connected without snooping USB. Current and serial responses do not change after connection.
+  * RF board should be easy to get as repair shops have huge stock from broken Xboxs
