LED Flash Click

LED Flash Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Software Support

Example Description

This application switching on and off led flash.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.LedFlash

Example Key Functions

• ledflash_cfg_setup Config Object Initialization function.

void ledflash_cfg_setup ( ledflash_cfg_t *cfg );

• ledflash_init Initialization function.

err_t ledflash_init ( ledflash_t *ctx, ledflash_cfg_t *cfg );

• ledflash_char_supcap_enable Charge Supercapacitor Enable function.

void ledflash_char_supcap_enable ( ledflash_t *ctx );

• ledflash_flash_enable Flash Enable function.

void ledflash_flash_enable ( ledflash_t *ctx );

• ledflash_flash_rdy_flag Check Flash Ready Flag function.

uint8_t ledflash_flash_rdy_flag ( ledflash_t *ctx );

Application Init

Initialization driver enables GPIO, starts write log and issues a warning.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ledflash_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.

    ledflash_cfg_setup( &cfg );
    LEDFLASH_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ledflash_init( &ledflash, &cfg );
    Delay_ms ( 100 );
    
    log_printf( &logger, "----------------------------------\r\n" );
    log_printf( &logger, " LED Flash Click \r\n" );
    log_printf( &logger, "----------------------------------\r\n" );
    log_printf( &logger, "/////////////////\r\n" );
    log_printf( &logger, " WARNING!!! \r\n" );
    log_printf( &logger, " DO NOT LOOK \r\n" );
    log_printf( &logger, " INTO THE LEDS, \r\n" );
    log_printf( &logger, " WHILE THAY ARE ON!!! \r\n" );
    log_printf( &logger, "/////////////////\r\n" );
    Delay_ms ( 1000 );
}

Application Task

This example demonstrates the use of LED Flash Click board by flashing with LEDs when ever supercapacitor is at a full voltage.

void application_task (  )
{
    uint8_t state;
    
    log_printf( &logger, " Charge Supercapacitor Enable \r\n" );
    ledflash_char_supcap_enable( &ledflash );
    Delay_ms ( 1000 );
    state = ledflash_flash_rdy_flag( &ledflash );

    if ( state == 0 )
    {
        log_printf( &logger, " Flash ON! \r\n" );
        ledflash_flash_enable( &ledflash );
    }
    else
    {
        log_printf( &logger, " Flash OFF! \r\n" );
        ledflash_flash_disable( &ledflash );
    }
    log_printf( &logger, "----------------------------------\r\n" );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
