Click library

  • Author : MikroE Team
  • Date : Feb 2020.
  • Type : SPI type

Software Support

We provide a library for the Mp3 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Mp3 Click driver.

Standard key functions :

  • mp3_cfg_setup Config Object Initialization function.

    void mp3_cfg_setup ( mp3_cfg_t *cfg ); 
  • mp3_init Initialization function.

    err_t mp3_init ( mp3_t *ctx, mp3_cfg_t *cfg );

Example key functions :

  • mp3_cmd_write Function writes one byte (command) to MP3

    void mp3_cmd_write( mp3_t *ctx, uint8_t address, uint16_t input );
  • mp3_data_write Function writes one byte ( data ) to MP3

    err_t mp3_data_write( mp3_t *ctx, uint8_t input );
  • mp3_data_write_32 Function Write 32 bytes ( data ) to MP3

    err_t mp3_data_write_32( mp3_t *ctx, uint8_t *input32 );

Example Description

This app demonstrates the use of MP3 Click by playing the specified sound from the mp3_resources.h file.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the default Click configuration.


void application_init ( void )
{
    log_cfg_t log_cfg;
    mp3_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    mp3_cfg_setup( &cfg );
    MP3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    mp3_init( &mp3, &cfg );

    mp3_reset( &mp3 );

    mp3_cmd_write( &mp3, MP3_MODE_ADDR, 0x0800 );
    mp3_cmd_write( &mp3, MP3_BASS_ADDR, 0x7A00 );
    mp3_cmd_write( &mp3, MP3_CLOCKF_ADDR, 0x2000 );

    // MP3 set volume, maximum volume is 0x00 and total silence is 0xFE.
    mp3_set_volume( &mp3, 0x2F, 0x2F );
    Delay_ms ( 1000 );

    log_info( &logger, " Application Task " );
}

Application Task

Playing the specified sound form the mp3_resources.h file.


void application_task ( void )
{
    uint32_t file_size = sizeof ( gandalf_sax_mp3_compressed );
    uint32_t file_pos = 0;
    uint8_t data_buf[ 32 ] = { 0 };

    log_printf( &logger, " Playing audio..." );
    for ( file_pos = 0; ( file_pos + 32 ) <= file_size; file_pos += 32 )
    {
        memcpy ( data_buf, &gandalf_sax_mp3_compressed[ file_pos ], 32 );
        while ( MP3_OK != mp3_data_write_32( &mp3, data_buf ) );
    }

    for ( ; file_pos < file_size; file_pos++ )
    {
        while ( MP3_OK != mp3_data_write( &mp3, gandalf_sax_mp3_compressed[ file_pos ] ) );
    }
    log_printf( &logger, "Done\r\n\n" );
}  

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Mp3

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.

Brushless 24 Click is a compact add-on board that controls brushless DC (BLDC) motors with any MCU. This board features the DRV10866, a 3- phase sensorless motor driver from Texas Instruments with integrated power MOSFETs with current drive capability up to 800mA peak. The DRV10866 implements a 150° commutation (sensorless BEMF control scheme) for a 3-phase motor alongside a synchronous rectification mode of operation that achieves increased efficiency for motor driver applications. Besides choosing the motor speed and a wide operating voltage range of up to 5V, it also has several built-in protection circuits, such as undervoltage, lock detection, voltage surge protection, and overtemperature.
