fbw_datalink module

Forward datalink over inter-mcu link between FBW and AP

Flight termination commands can still be decoded by FBW even when AP is down

Example for airframe file

Add to your firmware section: This example contains all possible configuration options, not all of them are mandatory!

<module name="fbw_datalink">
  b'<configure name="MODEM_PORT" value="UARTx" />\n    '
  b'<configure name="MODEM_BAUD" value="B57600" />\n    '
  b'<configure name="AUTOPILOT_PORT" value="UARTx" />\n  '
</module>
