LED Driver 8 Click

LED Driver 8 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.

Example Description

This example demonstrates the use of LED Driver 8 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.LedDriver8

Example Key Functions

• leddriver8_cfg_setup Config Object Initialization function.

void leddriver8_cfg_setup ( leddriver8_cfg_t *cfg );

• leddriver8_init Initialization function.

err_t leddriver8_init ( leddriver8_t *ctx, leddriver8_cfg_t *cfg );

• leddriver8_set_brightness Function for set Brightness.

void leddriver8_set_brightness ( leddriver8_t *ctx, uint8_t num_led, uint8_t value );

• leddriver8_set_output_gain Function for set output gain.

void leddriver8_set_output_gain ( leddriver8_t *ctx, uint8_t num_led, uint8_t value );

• leddriver8_set_mode_register Function for set mode registers.

void leddriver8_set_mode_register ( leddriver8_t *ctx, uint8_t mode_1, uint8_t mode_2 );

Application Init

Initializes the driver and configures the Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    leddriver8_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.

    leddriver8_cfg_setup( &cfg );
    LEDDRIVER8_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    leddriver8_init( &leddriver8, &cfg );

    leddriver8_reset( &leddriver8 );
    Delay_ms ( 500 );
    
    leddriver8_output_enable_pin( &leddriver8, LEDDRIVER8_ENABLE_LED_OUTPUTS );
    leddriver8_set_output_gain( &leddriver8, LEDDRIVER8_OUTPUT_GAIN_ALL_LED, LEDDRIVER8_FULL_OUTPUT_CURRENT_GAIN );
    leddriver8_set_mode_register( &leddriver8, LEDDRIVER8_MODE1_NORMAL_MODE, LEDDRIVER8_MODE2_DMBLNK_DIMMING |
                                  LEDDRIVER8_MODE2_CLRERR_ALL | LEDDRIVER8_MODE2_EXP_DISABLE );
    log_info( &logger, "---- Application Task ----" );
    Delay_ms ( 500 );
}

Application Task

Increases the LEDs brightness then toggles all LEDs with a one-second delay. Each step will be logged on the USB UART where you can track the program flow.

void application_task ( void )
{
    uint16_t cnt;

    log_printf( &logger, "Increasing LEDs brightness...\r\n" );
    log_printf( &logger, "----------------------------\r\n" );
    for ( cnt = LEDDRIVER8_MIN_BRIGHTNESS; cnt <= LEDDRIVER8_MAX_BRIGHTNESS; cnt++ )
    {
        leddriver8_set_brightness( &leddriver8, LEDDRIVER8_BRIGHTNESS_ALL_LED, cnt );
        Delay_ms ( 20 );
    }
    
    log_printf( &logger, "Toggling all LEDs...\r\n" );
    log_printf( &logger, "----------------------------\r\n" );
    for ( cnt = 0; cnt < 5; cnt++ )
    {
       leddriver8_set_brightness( &leddriver8, LEDDRIVER8_BRIGHTNESS_ALL_LED, LEDDRIVER8_MAX_BRIGHTNESS );
       Delay_ms ( 1000 );
       leddriver8_set_brightness( &leddriver8, LEDDRIVER8_BRIGHTNESS_ALL_LED, LEDDRIVER8_MIN_BRIGHTNESS );
       Delay_ms ( 1000 );
    }
}

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.
