LED Driver 7 Click

LED Driver 7 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.

Click Library

• Author : MikroE Team
• Date : Feb 2020.
• Type : I2C type

Software Support

Example Description

This application is portable lighting and rechargeable flashlights.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.LedDriver7

Example Key Functions

• leddriver7_cfg_setup Config Object Initialization function.

void leddriver7_cfg_setup ( leddriver7_cfg_t *cfg );

• leddriver7_init Initialization function.

err_t leddriver7_init ( leddriver7_t *ctx, leddriver7_cfg_t *cfg );

• leddriver7_generic_write Generic write function.

void leddriver7_generic_write ( leddriver7_t *ctx, uint8_t reg, uint8_t *data_buf, uint8_t len );

• leddriver7_generic_read Generic read function.

void leddriver7_generic_read ( leddriver7_t *ctx, uint8_t reg, uint8_t *data_buf, uint8_t len );

Application Init

Initalizes I2C driver and writes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    leddriver7_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.

    leddriver7_cfg_setup( &cfg );
    LEDDRIVER7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    leddriver7_init( &leddriver7, &cfg );

    Delay_ms ( 100 );
    log_printf( &logger, "-------------------- \r\n" );
    log_printf( &logger, " LED Driver 7 Click  \r\n" );
    log_printf( &logger, "-------------------- \r\n" );
}

Application Task

This example demonstrates the use of LED Driver 7 Click board, by cycling wiper positions of AD5171 Digital Potentiometer.

void application_task ( void )
{
    uint8_t n_pos = 0;
    uint8_t pos_num = 64;

    for ( n_pos = 12; n_pos < pos_num; n_pos++ )
    {
        leddriver7_generic_write( &leddriver7, LEDDRIVER7_NORM_OP_MODE, &n_pos, 1 );
        log_printf( &logger, "Position : %d \r\n", n_pos );
        Delay_ms ( 500 );
    }
}

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.
