// This example code runs on an Intel Edison and uses mraa to acquire data
// from an ADIS16448. This data is then scaled and printed onto the terminal.
// 
// This software has been tested to connect to an ADIS16448 through a level shifter
// such as the TI TXB0104. The SPI lines (DIN, DOUT, SCLK, /CS) are all wired through
// the level shifter and the ADIS16448 is also being powered by the Intel Edison.
