+Nintendo Wii Nunchuk controller
+-------------------------------------------------------------------------------
+
+This is a collection of example captures of I2C traffic from/to a Nintendo
+Wii Nunchuk game controller.
+
+A Dangerous Prototypes Buspirate (v4) was used as I2C master to talk to the
+Nunchuk controller.
+
+Details:
+https://en.wikipedia.org/wiki/Wiimote#Nunchuk

+
+
+Logic analyzer setup
+--------------------
+
+The logic analyzer used was a Saleae Logic (at 1MHz):
+
+  Probe       I2C pin
+  -------------------
+  3 (red)     SCL
+  7 (blue)    SDA
+
+
+Buspirate setup
+---------------
+
+Connections:
+
+  Buspirate   Nunchuk I2C breakout adapter
+  ----------------------------------------
+  GND         - (GND)
+  +3.3        + (VCC)
+  MOSI        d (SDA)
+  CLK         c (SCL)
+
+The basic setup after connecting to the Buspirate on /dev/ttyACM0
+(115200, 8n1) via minicom was:
+
+  HiZ>m (mode)
+  (1)>4 (I2C)
+  (1)>2 (I2C mode: hardware)
+  (1)>1 (speed: 100kHz)
+  I2C>W (enable Buspirate power supplies)
+
+See below for further per-file I2C commands used.
+
+
+sigrok
+------
+
+The sigrok command line used was:
+
+  sigrok-cli -d fx2lafw:samplerate=1mhz --time <ms> \
+             -p '3=SCL,7=SDA' -o <filename>
+
+The <ms> and <filename> parameters vary depending on the file.
