Enable CAN port, DroneCAN, and Configure for NEO-V2 Pro¶
See CAN Bus Setup and DroneCAN Setup for more information.
Set the following parameters in all parameter tables of Mission planner and restart after writing
CAN_P1_DRIVER set to 1.
CAN_P2_DRIVER set to 1.
CAN_D1_PROTOCOL set to 1.
CAN_D2_PROTOCOL set to 1.
NTF_LED_TYPES set to 231.
GPS1_TYPE set to 9.
NEO-V2 is now ready for operation
SLCAN Interface¶
If you need to set up NEO V2 PRO or upgrade its firmware, you need to enable SLCAN
Please connect NEO V2 pro to the autopilot’s CAN1 interface.
Open mission planner and connect autopilot.
Modify the following parameters in the Full Parameter tab of Mission Planner.
for CUAV V5+/nano:
CAN_SLCAN_CPORT set to 1
SERIAL7_PROTOCOL set to 22
Reboot autopilot
Note
CUAVV5 / NANO / FMUV5 autopilot running ArduPilot4.0 or later firmware will have two USB interfaces, one is autopilot’s console port (SERIAL0) running MAVLINK and one is an SLCAN interface port; if there are not two ports showing in the Mission Planner Comm Port drop-down box, please uninstall the driver and reinstall. If you continue to have problems, see Troubleshooting Composite Connections
For Pixhawk series / FMUv2 / FMU V3 / FMU V4
CAN_SLCAN_CPORT Set to 1
CAN_SLCAN_TIMOUT Set to 0 (no timeout, reboot to return to normal operation)
CAN_SLCAN_SERNUM Set to 0
Please do not reboot the autopilot until your operation is complete.
Note
STM32F4 does not support dual virtual USB ports, so autopilots using STM32F4 processor can only be used for SLCAN after the MAVLink connection on USB is closed; after writing the above settings, the USB interface becomes an SCLAN port; MAVLink connections can be made again after a reboot. Until then the USB connection can be used for SLCAN operations.
NEO-V2 Internal Configuration¶
ArduPilot supports setting DroneCAN device internal settings through SLCAN, such as modifying node ID; enabling / disabling barometer, etc.
Select the COMM port corresponding to SLCAN.
Select the DroneCAN section under Initial Setup>Optional Hardware tab.
Click “SLCAN NODE CAN1” and
Click “Inspector”
Change configuration parameters for DroneCAN device
Enable barometer
Baro_enabled=1, 0=disabled
Reboot
Modify device ID
Modify the CAN_NODE parameter
Upgrade Firmware¶
Method One： Firmware upgrade using Mission planner
Select the COMM port corresponding to SLCAN.
Click “SLCAN NODE CAN1” on the DroneCAN section under Initial Setup>Optional Hardware tab.
Click “Update”
Select “NO” in the pop-up prompt box (Tes is to select online firmware; No selects local firmware).
Select firmware file.
Wait for the flash process to complete.
Method Two：
Upgrade with DroneCAN GUI TOOL software
