I am using the BlueROV2 Heavy through QGC, RBP and the pixhawk, and want to add modes and controls for a robotic arm.
Currently, the arm controls are in an external controller (MyRio), but I want it to be controllable in QGC alongside with the BlueRov2. The plan is to add 3 modes (or modify exististing unused modes), that all stabilize the ROV, while one controls the robot arm with a joystick.
The pixhawk/RBP then sends a message to the MyRio about which robot arm mode is active.
The pixhawk/RBP then forwards all raw joystick button presses to the MyRio, where I can program processing of joystick controls for the robot arm in an environment, where I am more savvy.
In short I cant find out how I can send raw joystick commands out of the Pixhawk or (preferrably) the Raspberry Pi’s GPIO.
