Filename Description Size
beacon.zip Official EDU-RC code that generates the infrared beacon waveforms.
48,050
navigate.zip Infrared beacon tracking and navigation code used at the 2004 FRC kick-off. As there are two different versions of receiver.c, make sure that your sensors are attached according to the instructions at the top of receiver.c.

frc_tracker.zip Stand-alone example that demonstrates the infrared beacon tracker(s) without the navigation code. Start with this code if you want to write your own navigation code or just want to see the tracker(s) in action. A hint of how to calculate distance and heading to the beacon can be found in user_routines_fast.c/Process_Data_From_Local_IO( ). As there are two different versions of receiver.c, make sure that your sensors are attached according to the instructions at the top of receiver.c. Updated 2-24-04.

edu_tracker.zip Same as tracker.zip above, but runs on IFI's nifty EDU-RC. As there are two different versions of receiver.c, make sure that your sensors are attached according to the instructions at the top of receiver.c. Updated 2-17-04 to include IFI's latest default code and a bug fix in the interrupt code.
