C and H file to handle the AD5932 Programmable Frequency Scan Waveform Generator
To use this code in your project, do these:
-change AD5932_SetSPI() and AD5932_SendSPICommand() functions to your system's SPI commands
-replace SPARE0_on() ... SPARE3_off() GPIO pin on/off macros to your system's
-implement your delay_us() usec delay function
-call AD5932_Init() first, then call AD5932_SetSPI() to set the SPI port
-test your HW with this self-contained command: AD5932_TestSetup();
