Image acquisition device gets locked by faulty code

16 views (last 30 days)
I'm using the Image Acquisition Toolbox. Whenever my code fails and I have to debug and try again I get the following error:
Error using imaqdevice/start (line 89)
Multiple image acquisition objects cannot access the same device simultaneously.
Error in camera (line 6)
It looks like some image object is left on from the previous run, preventing me from creating a new image object, but I've tried deleting all variables from workspace, close all, clear all... the only thing that works is to re-start Matlab.
This is getting really annoying. Please help! /Chris

It seems like you have an active connection to the image acquisition device. Instead of closing MATLAB and re-opening - you can do either of the following: 1. delete(imaqfind) or 2. imaqreset
The above commands stops and deletes any active connection to the device from within MATLAB.
