The sensor connects the FPGA device through a SPI interface. In this demonstration, a SPI master
core is used by Nios II software to access the sensor’s Temperature Value registers. Based on the
register’s values reading out in every five seconds, the program calculates the centigrade degree.
The relative values are finally displayed onto the nios2-terminal window, in order to let the user
monitor the board real-time temperature.
