Virtual Window Function
We've been working on splitting the view of the camera with the Virtual_Window() function that Kevin supplied. We haven't had much success, but I now have a few questions.
1. What we attempted to do was put the camera in Raw Mode by calling Raw_Mode(5); and then waiting for an ACK, but we never recieved a response from the camera. Does anyone have any idea why?
2. We checked for ACKs and NCKs by placing flags in the Camera_State_Machine. We saw that the flags were set during initialization, and we call Camera_Handler() in user_routines, why would it not step through the state machine and set the flag after initialization?
3. When calling the Virtual Window funtion, why does Kevin write VW and then 4 before sending out the coordinates? In the CMUcam documentation it simply tells you to write out the coordinates.
4. After writing out the Virtual_Window() function we also did not recieve an ACK or NCK, similar to the Raw_Mode problem stated above.

FIRST is difficult and it is challenging, but you aren’t necessarily required to go off and build an 8 motor drivetrain and 4 motor / 8 pneumatic piston arm mechanism for the heck of it when a 2 motor non-shifting drivetrain and 2 motor arm does just as good a job. - Bill Gold [more]
