Click library

  • Author : MikroE Team
  • Date : Sep 2020.
  • Type : SPI type

Software Support

We provide a library for the LedDriver8 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 LedDriver8 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void leddriver8_cfg_setup ( leddriver8_cfg_t *cfg );

  • Initialization function.

    LEDDRIVER8_RETVAL leddriver8_init ( leddriver8_t ctx, leddriver8_cfg_t cfg );

Example key functions :

  • Function for set Brightness

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

  • Function for set output gain

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

  • Function for set mode registers

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

Examples Description

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

The demo application is composed of two sections :

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 );
    }
}

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.LedDriver8

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.
