I just received a 3-Axis gimbal with a Storm32 controller. I loaded the GUI and find that the board has version 090 firmware. The board is V 1.3.
I can read and write to the board with the GUI. I put a camera on the cradle and attached a 4S battery.
All that happens is that the motors - more or less "lock in place". They obviously have some current because they "cog". When I remove the battery, the cogging goes away.
I was going to update firmware using a USB <->RS-232(TTL) board, but I have no idea which pins on the interface to connect to. My board has only one pin labeled - GND.
I also do not know which pins I need to connect to change the pitch/roll/yaw.
Will someone please help? Attached is a screenshot of the first page of the GUI.
