MT9J001 hardware trigger

  1. Where did you get the camera module(s)?

  1. Model number of the product(s)?
  2. What hardware/platform were you working on?
    ubuntu ROS laptop using UC.391 RevD USB2 shield

I would like to know if it is possible to trigger the MT9J001 module using an external signal.

So far, I have found that it is possible to trigger the camera using the trigger pin on the USB shield. However, testing it using an LED, I found that the image is not at all taken when the pin goes high. How does this pin work? Is it like a software trigger?

After this I tried to trigger the camera using the GND and Trigger pins located on the camera board and it appears that the trigger pin is just connected to ground.

I tried changing register 12326 by following the aptina register datasheet. I couldnt enable the trigger using this method either. If bits 9:7 are set to 2 or 3, the register doesnt even retain its value but changing to a few different value, I’m not sure whats going on here…

I’m sorry to say that the camera does not have a hardware trigger.
