i'm trying to interface a cognex camera to an RJ3 controller, the karel program i am using works well for this with an r30ib plus, but not for the RJ3. Is there any trick for this? Or are there little differences between the 2 versions or karel? The program logs in fine, triggers the camera fine, i just can't get the read command to initialize the data coming from the camera. I am using WinOLPC+ to build the program in version 5.3 and it builds just fine.
