Library Description

The library covers all the necessary functions to control Buzz 3 Click board™. Library performs a standard GPIO interface communication.

Key functions:

• BUZZ3_RETVAL_T buzz3_set_gain_operating_mode ( uint8_t op_mode ) - Set gain operating mode function.

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO, set AN and RST pin as outputs, begins to write a log.
• Application Initialization - Initialization driver enables - GPIO and configures the appropriate MCU pin for sound generation, also write log.
• Application Task - (code snippet) This is an example that demonstrates the use of the Buzz 3 Click board™. This example plays the Imperial March using the sound library. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( )
{
    mikrobus_logWrite( "   Play the music    ", _LOG_LINE );
    buzz3_melody( );
    mikrobus_logWrite( "---------------------", _LOG_LINE );
    Delay_ms( 1000 );
}

Additional Functions :

• buzz3_sound_init( ) - Configures the appropriate MCU pin for sound generation.
• buzz3_melody( ) - Demo melody - plays Imperial March using Sound library.

Other mikroE Libraries used in the example:

• Sound
• UART

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
