1. All Mikroelektronika s development systems feature a large number of peripheral modules expanding microcontroller s range of application and making the process of program testing easier In addition to these modules it is also possible to use numerous additional modules linked to the development system through the I O port connectors Some of these additional modules can operate as stand alone devices without being connected to the microcontroller 7 MikroElektronika SOFTWARE AND HARDWARE SOLUTIONS FOR EMBEDDED WORLD waking ib siw ple EasyBuzz The EasyBuzz additional board is used to emit audio signals by using a piezo buzzer supplied on the board Key features 3 8kHz resonant frequency Low power consumption 3 3 or 5V DC power supply voltage Figure 1 EasyBuzz additional board How to connect the board The EasyBuzz additional board can be easily connected to a development system via a 2x5 connector CN1 on the additional board How to use the board In order to enable the EasyBuzz board to emit audio signals it is necessary to connect it to a development system and write the appropriate program to be loaded into the microcontroller The program should define which of the microcontroller pins will be used to generate a voltage signal of specific frequency Resonant frequency is 3 8kHz whereas frequencies in a range between 20Hz and 20kHz may also be used The best sound quality is ach2. ieved when using frequencies between 2 and 4kHz In order to connect the board to the microcontoller on the development system it is necessary to set the appropriate switch on DIP switch SW1 to the ON position It depends on the microcontroller pin used to emit voltage signal which one of these switches will be set ON MikroElektronika VCC Figure 2 EasyBuzz additional board connection schematic fl i Eg C121 ell ral mews 26 29mm WLWO BE EasyBUZZ HW REV 1 00 Figure 4 Additional board connected to a development system MikroElektronika 1odd s uenuo aouu mmm amp B UIO9 OJyIUU 3IJJo ze SN JOe UOD o e is u JOU op sjesodosd ss ulsnq 10 SIUSLULUOD suoijsenb Aue aaey no Jl ye 49491 INOA 9ejd se jd uoewoyzu jeuonppe pasu un o sjonpoid ino Jo Aue YUM suis qoid aulos SRE aJe noA jj WoT 3oy IU MMM ye IN Ino SIA sp ld slonpoud ind Jode aoi wea eter noA Jj QTYOM Q34aqGq38W3 YO4 SNOILNTOS JYVMCYVH ANY JYVMLAIOS
