Starlino used the Bus Pirate to explore a Freescale MMA7456L, a three-axis accelerometer with both I2C and SPI interfaces.
The surface mount chip is on a homemade though-hole breakout board, there’s also a tutorial on this handy adapter.
You can get a Bus Pirate for $30, including worldwide shipping at Seeed Studio. Adafruit also has the Bus Pirate and probe cables in stock and ready to ship.
An excellent tutorial indeed!
