Click library

  • Author : Stefan Filipovic
  • Date : Oct 2024.
  • Type : SPI type

Software Support

We provide a library for the Hall Current 21 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 21 Click driver.

Standard key functions :

  • hallcurrent21_cfg_setup Config Object Initialization function.

    void hallcurrent21_cfg_setup ( hallcurrent21_cfg_t *cfg );
  • hallcurrent21_init Initialization function.

    err_t hallcurrent21_init ( hallcurrent21_t *ctx, hallcurrent21_cfg_t *cfg );

Example key functions :

  • hallcurrent21_read_voltage_avg This function reads a desired number of ADC samples and calculates the average voltage level of the selected input channel.

    err_t hallcurrent21_read_voltage_avg ( hallcurrent21_t *ctx, uint8_t channel, uint16_t num_conv, float *voltage_avg );
  • hallcurrent21_calib_resolution This function reads the sensor voltage reference and calibrates the data resolution at a known load current.

    err_t hallcurrent21_calib_resolution ( hallcurrent21_t *ctx, float calib_current );
  • hallcurrent21_read_current This function reads the input current level [A].

    err_t hallcurrent21_read_current ( hallcurrent21_t *ctx, float *current );

Example Description

This example demonstrates the use of Hall Current 21 Click board by reading and displaying the input current measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and calibrates the data resolution at 3A load current.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    hallcurrent21_cfg_t hallcurrent21_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.
    hallcurrent21_cfg_setup( &hallcurrent21_cfg );
    HALLCURRENT21_MAP_MIKROBUS( hallcurrent21_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == hallcurrent21_init( &hallcurrent21, &hallcurrent21_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    log_printf( &logger, " Calibrating data resolution in 5 seconds...\r\n" );
    log_printf( &logger, " Keep the load current set at %.1fA during the calibration process.\r\n", 
                HALLCURRENT21_CALIBRATING_CURRENT );
    for ( uint8_t cnt = 5; cnt > 0; cnt-- )
    {
        log_printf( &logger, " %u\r\n", ( uint16_t ) cnt );
        Delay_ms ( 1000 );
    }
    if ( HALLCURRENT21_ERROR == hallcurrent21_calib_resolution ( &hallcurrent21, 
                                                                 HALLCURRENT21_CALIBRATING_CURRENT ) )
    {
        log_error( &logger, " Calibrate resolution." );
        for ( ; ; );
    }
    log_printf( &logger, " Data resolution calibration DONE.\r\n" );

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

Application Task

Reads the input current measurements and displays the results on the USB UART approximately once per second.

void application_task ( void )
{
    float current = 0;
    if ( HALLCURRENT21_OK == hallcurrent21_read_current ( &hallcurrent21, &current ) ) 
    {
        log_printf( &logger, " Current : %.1f A\r\n\n", current );
        Delay_ms ( 1000 );
    }
}

Note

The measurement range is approximately: +/- 65A.

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.HallCurrent21

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.

USB UART 5 Click

0

USB UART 5 Click is a compact add-on board with a general-purpose USB to UART serial interface. This board features the CP2110, a highly-integrated USB-to-UART bridge controller from Silicon Labs. The CP2110 uses the standard USB HID device class, requiring no custom driver and a UART interface that implements all RS-232 signals, including control and hardware handshaking, so existing system firmware does not need to be modified. The UART capabilities of the CP2110 also include baud rate support from 300 to 1Mbps, hardware flow control, RS-485 support, and GPIO signals that are user-defined for status and control information.

Current Limit 6 Click

0

Current Limit 6 Click is a compact add-on board representing a current-limiting solution. This board features the MAX17608, adjustable overvoltage, and overcurrent protection device from Maxim Integrated, now part of Analog Devices. This Click board™ is ideal for protecting systems with the flexible input overvoltage protection range from 4.5V to 60V, and the adjustable input undervoltage protection range is 4.5V to 59V. Also, the maximum current limit is 1A and can be programmed through a digital potentiometer MAX5401. When the device current reaches the programmed threshold, the device prevents further current increases by modulating the FET resistance.
