C.1. SP SDK functions
Function spTestBoard() should be called first to get and set the appropriate information of the board. Then
spSetHv(), spSetRC(),spSetGain(), spSetTrigLevel(), spSetTrigSource(), spHvSource(), spSetAvg().
For AD111 status call spReadInfo(), and for data call spReadDataEx().
Call spCloseEx() as the last function before exiting the AD111 software.
