Wii Nunchuk via Buspirate v4

The i2c/wii_nunchuk directory in sigrok-dumps contains a set of example captures of I2C traffic from/to a Nintendo Wii Nunchuk game controller.

The logic analyzer used was a Saleae Logic (at 1MHz). It is probing the Wii Nunchuk that is connected to a Dangerous Prototypes Buspirate (v4) that is used as I2C master to talk to the Nunchuk controller.

Probe setup:

Probe I2C pin
3 (red) SCL
7 (blue) SDA
