ROS for external trigger #75

Open habib-Boloorchi opened 5 years ago

habib-Boloorchi commented 5 years ago

is there any chance to change the ROS code to have an external trigger from e.g. pin20 and 21 of raspberry pi to get synched data from both cameras as stereo camera. I want to get 20 fps for it. and how to use mt9v034 's SDK for it.

Hi @habib-Boloorchi,

The trigger capture node works on both external trigger or software trigger. For external trigger, you can just pull the TRIGGER pin on the camera board to HIGH, and the image will be published to the output topic.
