Click library

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

Software Support

We provide a library for the IrBeacon 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 IrBeacon Click driver.

Standard key functions :

  • Config Object Initialization function.

    void irbeacon_cfg_setup ( irbeacon_cfg_t *cfg );

  • Initialization function.

    IRBEACON_RETVAL irbeacon_init ( irbeacon_t ctx, irbeacon_cfg_t cfg );

Example key functions :

  • Enable MOD function

    void irbeacon_enable_mod ( irbeacon_t *ctx );

  • Disable MOD function

    void irbeacon_disable_mod ( irbeacon_t *ctx );

  • Reset MOD function

    void irbeacon_reset_mod ( irbeacon_t *ctx );

Examples Description

This library contains an API for the IrBeacon Click driver. This application is suitable for high pulse current operation.

The demo application is composed of two sections :

Application Init

Enables GPIO and PWM, sets the frequency and duty cycle and enables PWM.


void application_init ( void )
{
    log_cfg_t log_cfg;
    irbeacon_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.

    irbeacon_cfg_setup( &cfg );
    IRBEACON_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    irbeacon_init( &irbeacon, &cfg );
    irbeacon_pwm_start( &irbeacon );

    log_info( &logger, "---- Application Task ----" );
    Delay_ms ( 1000 );
}

Application Task

This is a example which demonstrates the use of IR Beacon Click board. It shows how to enable the device and gradualy increase the duty cycle. 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;

    irbeacon_set_duty_cycle ( &irbeacon, duty );
    irbeacon_enable_mod( &irbeacon );
    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 ) 
    {
        irbeacon_disable_mod( &irbeacon );
        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.IrBeacon

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.

Current 7 Click is a compact add-on board providing a precise and accurate current sensing solution. This board features the INA282, a wide common-mode range, bidirectional, high-accuracy current shunt monitor from Texas Instruments. The INA282 represents a voltage output current shunt monitor that can sense drops across shunts at common-mode voltages from –14 V to +80 V, independent of the supply voltage, which operates in a range from 2.7V up to 18V supply. The zero-drift topology enables high-precision measurements with maximum input offset voltages as low as 70μV. Also, the user is allowed to process the output signal in analog or digital form.

Stepper 19 Click is a compact add-on board for precise control over stepper motors. This board features the DRV8424, a stepper motor driver from Texas Instruments designed to drive both industrial and consumer stepper motors. The DRV8424 has dual N-channel power MOSFET H-bridge drivers, a microstepping indexer, and integrated current sensing, eliminating the need for external power sense resistors. Operating on a 5V to 30V external power supply, the DRV8424 can deliver up to 2.5A of full-scale output current, with an internal PWM current regulation scheme that includes smart tune, slow, and mixed decay options to optimize performance. Ideal for applications in multichannel system monitoring, robotics, precision positioning, and automated manufacturing processes, this Click board™ appears as a versatile solution for sophisticated stepper motor control.
