  12. // This example code runs on an Intel Edison and uses mraa to acquire data
  13. // from an ADIS16448. This data is then scaled and printed onto the terminal.
  14. //
  15. // This software has been tested to connect to an ADIS16448 through a level shifter
  16. // such as the TI TXB0104. The SPI lines (DIN, DOUT, SCLK, /CS) are all wired through
  17. // the level shifter and the ADIS16448 is also being powered by the Intel Edison.
