Click library

  • Author : MikroE Team
  • Date : dec 2019.
  • Type : I2C type

Software Support

We provide a library for the AMRCurent 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 AMRCurent Click driver.

Standard key functions :

  • Config Object Initialization function.

    void amrcurent_cfg_setup ( amrcurent_cfg_t *cfg );

  • Initialization function.

    AMRCURENT_RETVAL amrcurent_init ( amrcurent_t ctx, amrcurent_cfg_t cfg );

  • Click Default Configuration function.

    void amrcurent_default_cfg ( amrcurent_t *ctx );

Example key functions :

  • This function writes data to the desired register.

    void amrcurent_generic_write ( amrcurent_t ctx, uint8_t reg, uint8_t data_buf, uint8_t len );

  • This function reads data from the desired register.

    void amrcurent_generic_read ( amrcurent_t ctx, uint8_t reg, uint8_t data_buf, uint8_t len );

  • This function read value.

    uint16_t amrcurrent_read_value ( amrcurent_t *ctx );

Examples Description

This application integrated bi-directional analog output current sensors.

The demo application is composed of two sections :

Application Init

Initializations driver init.


void application_init ( void )
{
    log_cfg_t log_cfg;
    amrcurent_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.

    amrcurent_cfg_setup( &cfg );
    AMRCURENT_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    amrcurent_init( &amrcurent, &cfg );
}

Application Task

Reading ADC data and converted current mA data from device and logs it to device.


void application_task ( void )
{
    //  Task implementation.

    read_adc_val = amrcurrent_read_value ( &amrcurent );
    log_printf( &logger, " - ADC value: \r\n ", read_adc_val );

    Delay_ms ( 100 );

    read_curr_val = amrcurrent_get_current (  &amrcurent );
    log_printf( &logger, " - Current value: \r\n ", read_curr_val );

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

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.AMRCurent

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.
