Click library

  • Author : Nikola Peric
  • Date : Mar 2022.
  • Type : PWM type

Software Support

We provide a library for the LedDriver5 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 LedDriver5 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void leddriver5_cfg_setup ( leddriver5_cfg_t *cfg );

  • Initialization function.

    LEDDRIVER5_RETVAL leddriver5_init ( leddriver5_t ctx, leddriver5_cfg_t cfg );

  • Click Default Configuration function.

    void leddriver5_default_cfg ( leddriver5_t *ctx );

Example key functions :

  • Generic sets PWM duty cycle.

    void leddriver5_set_duty_cycle ( leddriver5_t *ctx, pwm_data_t duty_cycle );

  • Stop PWM module.

    void leddriver5_pwm_stop ( leddriver5_t *ctx );

  • Start PWM module

    void leddriver5_pwm_start ( leddriver5_t *ctx );

Examples Description

This app enables usage of compact, high-efficiency, fixed frequency, synchronous step-up converter, optimized to drive one LED with the constant current.

The demo application is composed of two sections :

Application Init

Initialization driver enables - GPIO, PWM initialization set PWM duty cycle and start PWM.


void application_init ( void )
{
    log_cfg_t log_cfg;
    leddriver2_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.

    leddriver2_cfg_setup( &cfg );
    LEDDRIVER2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    leddriver2_init( &leddriver2, &cfg );

    leddriver2_pwm_start( &leddriver2 );
}

Application Task

This is an example that demonstrates the use of the LED Driver 5 Click board. This example shows the automatic control of Led light intensity, the first intensity of light is rising and then the intensity of light is falling. Results are being sent to the Usart Terminal where you can track their changes.


void application_task ( void )
{
    static int8_t duty_cnt = 1;
    static int8_t duty_inc = 1;
    float duty = duty_cnt / 10.0;

    leddriver5_set_duty_cycle( &leddriver5, duty );
    log_printf( &logger, "> Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );

    Delay_ms ( 500 );

    if ( 10 == duty_cnt ) 
    {
        duty_inc = -1;
    }
    else if ( 0 == duty_cnt ) 
    {
        duty_inc = 1;
    }
    duty_cnt += duty_inc;
}

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.LedDriver5

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.
