We are trying to interface two USB cameras (thermal or visible) on the rover to collect image data. Currently we are connecting them to the Pi from the USB port on the top of the rover. However, for syncronisation, we need an external trigger. I think the easiest would be to acces one of the GPIO pins on hExt on the Core 2 board.
How can I program a Core2 ROS pin output from a C++ application running on the Raspberry Pi? The current documentation only tells us whats currently being used.
I tried to compile the leo_firmware but ran into problem. Also, is the Leo Rover OS source available? I only found turtle_os.
