Frame Camera and Event Camera Synchronization

Use the frame camera as the master device, connecting the synchronization signal of the frame camera to the Trigger in interface of the event camera.

In the SDK, enable the Trigger in event callback function by calling the Trigger in related API :

#include "DvsenseDriver/camera/DvsCamera.hpp"
std::shared_ptr<dvsense::CameraTool> trigger_in_tool = device_->getTool(dvsense::ToolType::TOOL_TRIGGER_IN);
 
bool ret = trigger_in_tool->setParam("enable", true);
