What frequency will the two flag beacons work at?
20Hz and 30Hz. What can you tell us about detecting the flag? This is a fairly difficult technical task. Your team PIC expert should be brushing up on their programming, thinking in assembly, and worrying about each and every microsecond. Once you’ve got a plan to extend the PIC IR beacon (and you’ve gained some PIC experience), you should think about programming the PIC flag detector. This detector will obviously need to interface with a number of light detectors (which are detailed above) and will need to: • sample each of the detectors • decide if each detector is seeing a 20Hz or 30Hz signal • output the detect/not-detect 20Hz/30Hz signal to the HandyBoard The problem lies in the sampling and decision-making. It’s not difficult to perform a simple digital sample over time (say, xx samples over .1 seconds). If the signals were digital, it’d be easy enough to decide if there were two oscillations (each taking 0.05s, or 20Hz) or three oscillations (each taking 0.033s, or 30Hz). It’s t
