A device may include polling logic configured to store a table of received addresses, sequentially receive sensor data from each address in the table via a serial data bus, store the sensor data in a memory, receive an address from a processor via a high speed data bus, and provide stored sensor data from the memory to the processor via a parallel data bus. The serrated grooves are defined by opposed side walls each having at least one step portion intermediate the length thereof. The method also includes providing a first user interface object associated with the first axis and providing a second user interface object associated with the second axis.
