  • Author : Stefan Ilic
  • Date : Sep 2023.
  • Type : I2C type

Software Support

We provide a library for the LED Flash 3 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 LED Flash 3 Click driver.

Standard key functions :

  • ledflash3_cfg_setup Config Object Initialization function.

    void ledflash3_cfg_setup ( ledflash3_cfg_t *cfg );
  • ledflash3_init Initialization function.

    err_t ledflash3_init ( ledflash3_t *ctx, ledflash3_cfg_t *cfg );
  • ledflash3_default_cfg Click Default Configuration function.

    err_t ledflash3_default_cfg ( ledflash3_t *ctx );

Example key functions :

  • ledflash3_write_reg LED Flash 3 register writing function.

    err_t ledflash3_write_reg ( ledflash3_t *ctx, uint8_t reg, uint8_t data_in );
  • ledflash3_set_flash_current LED Flash 3 set flash current function.

    err_t ledflash3_set_flash_current ( ledflash3_t *ctx, float flash_current );
  • ledflash3_set_torch_current LED Flash 3 set torch current function.

    err_t ledflash3_set_torch_current ( ledflash3_t *ctx, float torch_current );

Example Description

This app demonstrate flash mode on LED Flash 3 Click.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    ledflash3_cfg_t ledflash3_cfg;  /**< Click config object. */

    /** 
     * 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.
    ledflash3_cfg_setup( &ledflash3_cfg );
    LEDFLASH3_MAP_MIKROBUS( ledflash3_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == ledflash3_init( &ledflash3, &ledflash3_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( LEDFLASH3_ERROR == ledflash3_default_cfg ( &ledflash3 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

Turning the LED on for a second and off for another second.

void application_task ( void ) 
{
    ledflash3_strobe_pin( &ledflash3 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

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.LEDFlash3

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.
