Controll over Radio?

[interfect]

Sorry. I guess I didn't make myself clear. Basically, what we want to do is transmit arbitrary bytes from the robot, through the radio link, and out the dashboard port. However, we want to do it on an interrupt basis rather than a loop basis, or as close to an interrupt basis as possible (maybe from the fast user code?). Are the packets sent to the OI constructed by the master uP? Can we hack it to send our own byte stream? If we add stuff to the txdata typedef, tx_data_record, can we trick the master uP into sending it? Or would it just balk? What feilds of that structure are "safe" to set to send arbitrary data? If we made our own structure of the same size, what bytes could we use?
