Software Configuration Files give the Evaluation Board Controller software information on how the software and hardware
should perform . T hey contain information such as the name of the DSP program to download, the default and maximum
sample frequencies, the number of samples to take and the power supply settings to use. A typical Software Configuration File
(*.cfg) is shown in T able V.
