Hardware Trigger Function
Hardware trigger mode is available only when the camera works at slave mode, in slave mode
the camera will wait for the hardware trigger signal on Ext_Trigger.
The EXT_Trigger signal is to driver the MOSFET, External input trigger signal voltage should
range 3.3V-20V, driving current ability should be more than 5mA;
You can use input pin Ext_Trigger to send a hardware trigger signal to the camera. The
hardware trigger can be used to trigger the acquisition start.
A hardware debouncer circuit
shall be considered on the EXT_Trigger line.
By default, the hardware trigger is rising edge activated, refer to below exposure timing:
