-This is an example application for accessing the EMAC interface for the on-board DtoA of the SoM-150ES. This interface uses the EMAC ioex class to provide a GPIO-like interface (see also the [http://wikidev.emacinc.com/wiki/Example_egpc egpc project]). This application outputs a sine wave on channel 0 and a cosine wave on channel 1.
