Click library

  • Author : Nenad Filipovic
  • Date : Aug 2023.
  • Type : SPI type

Software Support

We provide a library for the Hall Current 17 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Hall Current 17 Click driver.

Standard key functions :

  • hallcurrent17_cfg_setup Config Object Initialization function.

    void hallcurrent17_cfg_setup ( hallcurrent17_cfg_t *cfg );
  • hallcurrent17_init Initialization function.

    err_t hallcurrent17_init ( hallcurrent17_t *ctx, hallcurrent17_cfg_t *cfg );
  • hallcurrent17_default_cfg Click Default Configuration function.

    err_t hallcurrent17_default_cfg ( hallcurrent17_t *ctx );

Example key functions :

  • hallcurrent17_get_current Hall Current 17 get current function.

    err_t hallcurrent17_get_current ( hallcurrent17_t *ctx, float *current );
  • hallcurrent17_get_vout Hall Current 17 get Vout function.

    err_t hallcurrent17_get_vout ( hallcurrent17_t *ctx, float *adc_vout );
  • hallcurrent17_get_vref Hall Current 17 get Vref function.

    err_t hallcurrent17_get_vref ( hallcurrent17_t *ctx, float *adc_vref );

Example Description

This example demonstrates the use of Hall Current 17 Click board™ by reading and displaying the current measurements.

The demo application is composed of two sections :

Application Init

The initialization of SPI module and log UART. After driver initialization, the app sets the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    hallcurrent17_cfg_t hallcurrent17_cfg;  /**< Click config object. */

    /** 
     * 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.
    hallcurrent17_cfg_setup( &hallcurrent17_cfg );
    HALLCURRENT17_MAP_MIKROBUS( hallcurrent17_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == hallcurrent17_init( &hallcurrent17, &hallcurrent17_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( HALLCURRENT17_ERROR == hallcurrent17_default_cfg ( &hallcurrent17 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

The demo application reads the current measurements [A] and displays the results. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
    static float current = 0.0;
    if ( HALLCURRENT17_OK == hallcurrent17_get_current( &hallcurrent17, &current ) )
    {
        log_printf( &logger, " Current: %.3f [A]\r\n", current );
    }
    log_printf( &logger, " --------------------\r\n" );
    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.HallCurrent17

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. UART terminal is available in all MikroElektronika compilers.

Altitude 5 Click

0

Altitude 5 Click is a compact add-on board allowing high-resolution barometric pressure measurement. This board features the KP236, an analog barometric air pressure sensor based on a capacitive principle from Infineon Technologies. The KP236 is primarily developed for measuring barometric air pressure but can also be used in other application fields. It is surface micro-machined with a monolithic integrated signal conditioning circuit implemented in BiCMOS technology. The calibrated transfer function converts pressure into an analog output signal in a range of 40kPa to 115kPa. However, the choice of signal processing is up to the user; more precisely, the user can process the output signal in analog or digital form. The high accuracy and the high sensitivity of the KP236 make this Click board™ suitable for advanced automotive applications and industrial and consumer applications.
