# NMEA 2000 EFI driver
|
||
|
|
|
||
|
|
This driver implements support for marine EFI systems using NMEA 2000
|
||
|
|
CAN messages.
|
||
|
|
|
||
|
|
# Parameters
|
||
|
|
|
||
|
|
The script used the following parameters:
|
||
|
|
|
||
|
|
## EFI_2K_ENABLE
|
||
|
|
|
||
|
|
this must be set to 1 to enable the driver
|
||
|
|
|
||
|
|
## EFI_2K_OPTIONS
|
||
|
|
|
||
|
|
This sets options for the driver. Currently the only option is to set
|
||
|
|
EFI_2K_OPTIONS to 1 to enable logging of the raw CAN frames for
|
||
|
|
debugging purposes.
|
||
|
|
|
||
|
|
# Operation
|
||
|
|
|
||
|
|
This driver should be loaded by placing the lua script in the
|
||
|
|
APM/SCRIPTS directory on the microSD card, which can be done either
|
||
|
|
directly or via MAVFTP. The NMEA_2000.lua module from
|
||
|
|
AP_Scripting/modules/ also needs to be put in the APM/SCRIPTS/MODULES directory.
|
||
|
|
|
||
|
|
The following key parameters should be set:
|
||
|
|
|
||
|
|
- SCR_ENABLE should be set to 1
|
||
|
|
- EFI_TYPE should be set to 7
|
||
|
|
- EFI_2K_ENABLE should be set to 1
|
||
|
|
- EFI_2K_CANDRV needs to be set to the CAN driver number
|
||
|
|
- CAN_Pn_BITRATE needs to be set to 250000
|
||
|
|
- CAN_Dn_PROTOOCOL needs to be set to 10 for scripting
|
||
|
|
|
||
|
|
then the flight controller should rebooted and parameters should be
|
||
|
|
refreshed.
|
||
|
|
|
||
|
|
Once loaded the EFI_2K_ENABLE parameters will appear and should be set
|
||
|
|
according to the parameter list above.
|
||
|
|
|
||
|
|
The GCS will receive EFI_STATUS MAVLink messages which includes RPM,
|
||
|
|
cylinder head temperature, exhaust gas temperature, injection timing,
|
||
|
|
engine load, fuel consumption rate, throttle position atmospheric
|
||
|
|
pressure and ignition voltage.
