UNI-DS6
9. Piezo buzzer
Due to a built-in piezo buzzer, the UNI-DS6 development system is capable of emitting audio signals� In order to enable
the piezo buzzer to operate properly it is necessary to generate a voltage signal of specific frequency. Remember, when
writing code for voltage signal generation, that the piezo buzzer’s resonant frequency is 3�8kHz� Other frequencies in
the range between 20Hz and 20kHz can also be used, but the best performance is provided with frequencies ranging
between 2kHz and 4kHz� To establish connection between the piezo buzzer and the microcontroller, it is necessary to
place jumper J14 in adequate position� If jumper J14 is placed in the RC1 position the RC1 MCU pin is used for signal
generation, Figure 9-2� Otherwise place jumper J14 in the RA4 position in order to use the RA4 MCU pin for signal
generation, Figure 9-3�
