Vibra

A vibra alerting device is used to generate a vibration signal for an incoming call. Vibra is
located in the left side of the phone just above the battery block and it is SMD compo-
nent. Vibra interface is the same like other DCT4 projects. The vibra is controlled by a
PWM signal from the UEMEK. Frequency can be set to 64, 129, 258 or 520 Hz and duty
cycle can vary between 3% - 97%.
