1. introduction buzz click is an accessory board in mikrobus ? form factor. board features a piezo speaker capable of emitting audio signals. buzzers resonant frequency is 3.8khz (where you can expect its best performance). on-board buzzer driver can be connected to either digital (gpi) or pwm line. you can use either of those two pins to provide the signal from the microcontroller to the buzzer driver. board is set to use 5v power supply by default. solder pwr sel smd jumper to 3.3v position if used with 3.3v systems. once you have soldered the headers your board is ready to be placed into desired mikrobus? socket. make sure to align the cut in the lower-right part of the board with the markings on the silkscreen at the mikrobus? socket. if all the pins are aligned correctly, push the board all the way into the socket. 3. plugging the board in 2 3 2. soldering the headers 1 4. creating sound on-board buzzer driver can be connected to either digital (gpi) or pwm line. you can create sound using sound library supported in mikroelektronika compilers, or utilize microcontroller internal pwm module to create the signal for the buzzer. signal frequency determines the sound pitch, and the duty cycle determines the amplitude (sound volume). turn the board upward again. make sure to align the headers so that they are perpendicular to the board, then solder the pins carefully. turn the board upside down, so that bottom side is facing you upwards. place shorter parts of the header pins in the both soldering pad locations. buzz click front and back side appearance of the buzz click board before using your click board, make sure to solder the provided 1x8 male headers to both sides of the board. two 1x8 male headers are included with the board in the package. click board www.mikroe.com buzz click manual ver. 1.00 0 100000 020043
8. support mikroelektronika ofers free tech support (www.mikroe.com/esupport) until the end of product lifetime, so if something goes wrong, we are ready and willing to help! 7. code examples .com once you have done all the necessary preparations, its time to get your click board up and running. we have provided the examples for mikroc, mikrobasic and mikropascal compilers on our libstock website. just download them and you are ready to start. 6. power supply selection on-board pwr sel zero- ohm resistor (smd jumper) is used to determine whether 5v or 3.3v power supply is used. this resistor is provided in 5v position by default. in order to use buzz click with 3.3v development system, it is necessary to resolder this jumper to +3.3v position. 5. buzz click board schematics p1 an rst cs sck mosi miso +3.3v gnd pwm int rx tx scl sda +5v gnd 1 2 3 j1 vcc +5v +3v3 p0 p1 p0 buzzer 1 2 j3 1 2 j2 r2 1k r1 10k q1 bc846 vcc buzzer e1 10uf r3 2k2 vcc vcc pwr pz1 buzzer mikroelektronika assumes no responsibility or liability for any errors or inaccuracies that may appear in the present document. specifcation and information contained in the present schematic are subject to change at any time without notice. copyright ? 2012 mikroelektronika. all rights reserved.
