    We have a HW/SW example on how to do simple FSK type comms across the power line using an AFE031 and F2837x or F28004x.

    The application note is here and can be used with LAUNCHXL-F28379D or LAUNCHXL-F280049C and the AFE031 Booster Pack .

    While this was designed to demonstrate comms across the DC bus in a solar panel system, I believe there is some additional instruction in the AFE031 BP User Guide on configuring for use on an AC line.  The code is open source so that you can modify as needed for your system.

    With this implementation there will be MIPs left over in the C2000 to do other real time control in your system.

    Best,
