Click library

  • Author : Luka Filipovic
  • Date : Jul 2021.
  • Type : SPI type

Software Support

We provide a library for the VCPMonitor4 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 VCPMonitor4 Click driver.

Standard key functions :

  • vcpmonitor4_cfg_setup Config Object Initialization function.

    void vcpmonitor4_cfg_setup ( vcpmonitor4_cfg_t *cfg );
  • vcpmonitor4_init Initialization function.

    err_t vcpmonitor4_init ( vcpmonitor4_t *ctx, vcpmonitor4_cfg_t *cfg );
  • vcpmonitor4_default_cfg Click Default Configuration function.

    err_t vcpmonitor4_default_cfg ( vcpmonitor4_t *ctx );

Example key functions :

  • vcpmonitor4_get_vbus Get BUS voltage.

    err_t vcpmonitor4_get_vbus ( vcpmonitor4_t *ctx, float *vbus )
  • vcpmonitor4_get_current Get Current.

    err_t vcpmonitor4_get_current ( vcpmonitor4_t *ctx, float *current )
  • vcpmonitor4_get_power Get Shunt voltage.

    err_t vcpmonitor4_get_power ( vcpmonitor4_t *ctx, float *power )

Example Description

This example application showcases ability of Click board to be configured for different readings and read temperature, voltage, current and power.

The demo application is composed of two sections :

Application Init

Initialization of communication modules (SPI, UART) and additional alert pin. Reads Manufacturer and Device ID, Configurates device for reading all device measurements.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    vcpmonitor4_cfg_t vcpmonitor4_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.
    vcpmonitor4_cfg_setup( &vcpmonitor4_cfg );
    VCPMONITOR4_MAP_MIKROBUS( vcpmonitor4_cfg, MIKROBUS_1 );
    err_t init_flag  = vcpmonitor4_init( &vcpmonitor4, &vcpmonitor4_cfg );
    VCPMONITOR4_SET_DATA_SAMPLE_EDGE
    if ( SPI_MASTER_ERROR == init_flag )
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    uint32_t temp_data = 0;
    vcpmonitor4_generic_read( &vcpmonitor4, VCPMONITOR4_REG_MANUFACTURER_ID, &temp_data );
    log_printf( &logger, " > Manufacturer ID: \t0x%.4X\r\n", temp_data );

    vcpmonitor4_generic_read( &vcpmonitor4, VCPMONITOR4_REG_DEVICE_ID, &temp_data );
    log_printf( &logger, " > Device ID: \t\t0x%.4X\r\n", temp_data );

    vcpmonitor4_default_cfg ( &vcpmonitor4 );
    Delay_ms ( 1000 );
    log_info( &logger, " Application Task " );
}

Application Task

In span of 500ms reads and calculates data for IC temperature, Bus voltage in V, Shunt voltage in mV, and current and power for device.


void application_task ( void )
{
    float read_data;
    vcpmonitor4_get_temperature( &vcpmonitor4, &read_data );
    log_printf( &logger, " > Temperature:\t%.2f \r\n", read_data );

    vcpmonitor4_get_vbus( &vcpmonitor4, &read_data );
    log_printf( &logger, " > Vbus[V]:\t%.2f \r\n", read_data );

    vcpmonitor4_get_vshunt( &vcpmonitor4, &read_data );
    log_printf( &logger, " > Vshunt[mV]:\t%.2f \r\n", read_data );

    vcpmonitor4_get_current( &vcpmonitor4, &read_data );
    log_printf( &logger, " > Current[A]:\t%.2f \r\n", read_data );

    vcpmonitor4_get_power( &vcpmonitor4, &read_data );
    log_printf( &logger, " > Power[W]:\t%.2f \r\n", read_data );
    log_printf( &logger, "*************************\r\n" );

    Delay_ms ( 500 );
}

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.VCPMonitor4

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.
