This is the software component for the Monophonic to Stereophonic Converter.

The application works with two threads, which communicate with message passing:

• UI Thread - the thread in charge of rendering the UI and managing input
• Communication Thread - the thread in charge of communicating with the circuit over the SPI interface

The modules in the code are arranged likewise, with UI code in the ui folder, and the communication in the spi folder.

The user interface allows the user to set a spacial simulation mode to configure how the output sound is located in perceptual space:

• constant: move the sound to a specific location, represented as an angle relative to straight ahead
• circular: move the sound in a circle around the listener

The SPI module works as a state machine, based on the current mode that the UI is in. It accepts messages that change the state.
