DJI RS2 and RS3-Pro Mount Driver

DJI RS2 and RS3-Pro gimbal mount driver lua script

How to use

  • Connect gimbal to autopilot's CAN1 port or CAN2 port
  • If connected to CAN1, set CAN_D1_PROTOCOL = 10 (Scripting), CAN_P1_DRIVER = 1 (First driver)
  • If connected to CAN2, set CAN_D2_PROTOCOL = 10 (Scripting), CAN_P2_DRIVER = 2 (Second driver)
  • Set SCR_ENABLE = 1 to enable scripting
  • Set SCR_HEAP_SIZE = 120000 (or higher)
  • Set MNT1_TYPE = 9 (Scripting) to enable the mount/gimbal scripting driver
  • Reboot the autopilot
  • Copy the mount-djirs2-driver.lua script to the autopilot's SD card in the APM/scripts directory and reboot the autopilot

Advanced usage

  • The gimbal can be connected to an existing DroneCAN bus (on ArduPilot 4.6 or later) by setting CAN_Dx_PROTOCOL2=10 on that bus's driver
  • The gimbal can be used as the Nth mount (instead of the first) by setting MNTn_TYPE = 9 and modifying the script's user definitions
  • The gimbal can be used with the Scripting2 protocol by modifying the script's user definitions
  • Multiple gimbals can be used at once by duplicating the script and connecting them to different buses

Issues

If the ground station reports "Pre-arm: Mount not healthy", update the gimbal firmware using the DJI Ronin phone app to version 01.04.00.20 or later to correct a mismatch in the way data is received from the gimbal. Completing this update may take more than an hour.
