gps_furuno module

Furuno GPS (UART)

Driver for Furuno GPS modules parsing the NMEA protocol with Furuno extensions.

Example for airframe file

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

1 <module name="gps_furuno">
2  <configure name="FURUNO_GPS_PORT" value="UARTx" />
3  <configure name="FURUNO_GPS_BAUD" value="B38400" />
4 </module>

Module configuration options

Configure Options

  • name: FURUNO_GPS_PORT value: UARTx
    Description: UART where the GPS is connected to (UART1, UART2, etc
  • name: FURUNO_GPS_BAUD value: B38400
    Description: UART baud rate

Auto-loaded modules

The following modules are automatically loaded (just as if you had added them in the airframe file)

Module functions

Init Functions

These initialization functions are called once on startup.

Event Functions

These event functions are called in each cycle of the module event loop.

Periodic Functions

These functions are called periodically at the specified frequency from the module periodic loop.

Files

Header Files

The following headers are automatically included in modules.h
