The problem with the PXC200 (apart from imagenation's wonderful policy regarding documentation, which is really not warranted given the board's quality - sorry guys, if I unplug a camera, I don't regard my system freezing as acceptable) is that there are at least two different models out there (as in different on-board hardware) but with the same model number. Alessandro's driver was able to handle this (I think), but when I put his code into bttv, it was a quick cut'n'paste job so it only initialises my model of the board properly. > > Which is a little strange: shouldn't I2CRead return different > > values?

(And I do get the same values read back as well) -- Mark Dennehy, Email : Mark.Dennehy@xxxxxxxxx Research Student, Computer Vision and Robotics Research Group, Computer Science Dept., Trinity College Dublin
