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 |
