Hi all, I'm Huy from Gremsy.
This is my first time posting here, sorry for my absence although you guys mentioned me for quite a long time.
Regarding CAN protocol for GREMSY gimbal, all we need is attitude information (pitch, roll) from PIXHAWK controller to correct horizon drift . Our engineeer has experimented with pixhawk code but unfortunately CAN message which contains attitude information is not implemented in the pixhawk source code yet
But luckily, we found a solution to get attitude information on the MAVLINK protocol via serial communication and we applied already for T1, T3 gimbals
