Armadillo: Audio Play


The Armadillo features an on board amplifier and tiny speaker, which are connected to the line out pin which is present on the H2 header. The on board speaker is small and designed only to provide a small level of audio capability to the display module. If the audio level is raised too high in software, it can cause the output to distort and become inaudible. The on-board audio capability of the Armadillo is mono only, and features only a single (mono) line out signal.

This application video demonstrates the basic application of the PWM audio feature of the Armadillo-43/T.
