melody generator provided by the kernel, complex melodies can be generated following a melody structure.
2.6 USB Datalink
This includes the physical components that allows two-way communications between the watch and the
PC. The PC serves as a user interface to the watch. It coordinates and controls the information that will be
transferred to and from the watch. With the PC, the user can do the following:
• Activate or deactivate applications
• Customized mode names
• Select the order of the active applications in the mode list
• Set time and date
• Download EEPROM-based applications
• Download new databases for active applications
• Upload information stored in the watch
• Etc.
An internal application, COMMUNICATION MODE, interprets and processes all the commands being
sent from the PC. This mode is automatically enabled when an active USB cable is plugged to the watch.
