Click library

  • Author : MikroE Team
  • Date : May 2020.
  • Type : GPIO type

Software Support

We provide a library for the IndexCounter 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 IndexCounter Click driver.

Standard key functions :

  • Config Object Initialization function.

    void indexcounter_cfg_setup ( indexcounter_cfg_t *cfg );

  • Initialization function.

    INDEXCOUNTER_RETVAL indexcounter_init ( indexcounter_t ctx, indexcounter_cfg_t cfg );

  • Click Default Configuration function.

    void indexcounter_default_cfg ( indexcounter_t *ctx );

Example key functions :

  • This function returns a state of the direction DIR ( AN ) pin.

    uint8_t indexcounter_get_dir ( indexcounter_t *ctx );

  • This function returns a state of the speed SPD ( RST ) pin.

    uint8_t indexcounter_get_speed ( indexcounter_t *ctx );

Examples Description

This application enables usage of Index counter Click board which can be used to measure rotational speed.

The demo application is composed of two sections :

Application Init

Initilaziation of GPIO and write log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    indexcounter_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.

    indexcounter_cfg_setup( &cfg );
    INDEXCOUNTER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    indexcounter_init( &indexcounter, &cfg );
}

Application Task

This is an example which demonstrates the use of the Index Counter Click board. This example shows the direction of movement, Rotations Per Minute ( RPM or speed ) of the three pairs of rotating poles positioned in the sensor operating range. Results are being sent to the Usart Terminal where you can track their changes.


void application_task ( void )
{
    //  Task implementation.

    speed_state = indexcounter_get_speed( &indexcounter );
    dir_state = indexcounter_get_dir( &indexcounter );

    if ( enable_speed && speed_state )
    {
        pulse_ms = time_cnt - start_timer;
        start_timer = time_cnt;
        speed_rpm = INDEXCOUNTER_ONE_MIN_CONV_MS / ( pulse_ms * n_pole_pairs );
        enable_speed = INDEXCOUNTER_SPEED_DISABLE;

        log_display ( speed_rpm );
    }

    if ( ( !enable_speed ) && ( !speed_state ) )
    {
        enable_speed = INDEXCOUNTER_SPEED_ENABLE;
    }

    Delay_1ms();
    time_cnt++;
}

Note

Additional Functions :

  • void log_display ( float rpm_val ) - The function displays all results and a float value with a comma with two decimal places.

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.IndexCounter

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.

Magneto 11 Click is a compact add-on board that contains an accurate and reliable magnetic sensing device. This board features the AS5510, a linear hall sensor with 10-bit resolution, and an I2C interface from ams AG. It can measure the absolute position of lateral movement of a simple 2-pole magnet. A lateral stroke of 0.5mm ~ 2mm can be measured with air gaps around 1.0mm, depending on the magnet size. The AS5510 may be switched to a Power-Down state when it is not used to conserve power. This Click board™ is suitable for position sensing applications requiring a small magnetic range where noise is a critical design parameter.
