Functions | |
uint8_t | SignalAlongTrackdir (Trackdir trackdir) |
Maps a trackdir to the bit that stores its status in the map arrays, in the direction along with the trackdir. | |
uint8_t | SignalAgainstTrackdir (Trackdir trackdir) |
Maps a trackdir to the bit that stores its status in the map arrays, in the direction against the trackdir. | |
uint8_t | SignalOnTrack (Track track) |
Maps a Track to the bits that store the status of the two signals that can be present on the given track. | |
