Click library

  • Author : Nenad Filipovic
  • Date : Apr 2021.
  • Type : GPIO type

Software Support

We provide a library for the Speaker Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on mikroE github account.

Library Description

This library contains API for Speaker Click driver.

Example Description

This library contains API for the Speaker click driver. This application controls the operating modes of the Speaker click boardâ„¢.

The demo application is composed of two sections :

Application Init

Initialization of GPIO module and log UART. After driver initialization, the application performs the default settings.

void application_init ( void ) {
log_cfg_t log_cfg;
speaker_cfg_t speaker_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_printf( &logger, "\r\n" );
log_info( &logger, " Application Init " );
// Click initialization.
speaker_cfg_setup( &speaker_cfg );
SPEAKER_MAP_MIKROBUS( speaker_cfg, MIKROBUS_1 );
if ( speaker_init( &speaker, &speaker_cfg ) == DIGITAL_OUT_UNSUPPORTED_PIN ) {
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
speaker_default_cfg ( &speaker );
log_info( &logger, " Application Task " );
Delay_ms( 100 );
}

Application Task

This is an example that shows the use of a Speaker click boardâ„¢. The task of the application consists of switching two modes of operation: normal and shutdown modes. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void ) {
log_printf( &logger, "-------------------------\r\n" );
log_printf( &logger, " Normal Operation Mode \r\n" );
Delay_ms( 10000 );
log_printf( &logger, "-------------------------\r\n" );
log_printf( &logger, " Enter Shutdown Mode \r\n" );
speaker_shutdown( &speaker );
Delay_ms( 10000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on mikroE github account.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Speaker

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. UART terminal is available in all Mikroelektronika compilers.
