This sample shows how to synchronize the image acquisition of two cameras by using the PWM (pulse width modulation) output of the master camera. Both cameras (master and slave) are running in hardware triggered mode (rising edge) and wait for a trigger signal on their GPIO 1 as trigger input. The trigger signal is generated by the PWM output on the GPIO 2 of the master camera.
Thus, the image acquisition of both cameras is done simultaneously.
