LED Flash click

LED Flash click functions as a high power LED flash, and carries the CAT3224 flash LED driver. The click is designed to run on a 5V power supply.

Click library

• Author : MikroE Team
• Date : Dec 2019.
• Type : GPIO type

Software Support

We provide a library for the LedFlash 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 LedFlash Click driver.

Standard key functions :

• Config Object Initialization function.

void ledflash_cfg_setup ( ledflash_cfg_t *cfg );

• Initialization function.

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

Example key functions :

• Charge Supercapacitor Enable function

void ledflash_char_supcap_enable ( ledflash_t *ctx );

• Flash Enable function

void ledflash_flash_enable ( ledflash_t *ctx );

• Check Flash Ready Flag function

uint8_t ledflash_flash_rdy_flag ( ledflash_t *ctx );

Examples Description

This application switching on and off led flash.

The demo application is composed of two sections :

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" );
}

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.LedFlash

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.
