Click library

  • Author : Mikroe Team
  • Date : Oct 2021.
  • Type : I2C/SPI type

Software Support

We provide a library for the VCPMonitor3 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 VCPMonitor3 Click driver.

Standard key functions :

  • vcpmonitor3_cfg_setup Config Object Initialization function.

    void vcpmonitor3_cfg_setup ( vcpmonitor3_cfg_t *cfg );
  • vcpmonitor3_init Initialization function.

    err_t vcpmonitor3_init ( vcpmonitor3_t *ctx, vcpmonitor3_cfg_t *cfg );
  • vcpmonitor3_default_cfg Click Default Configuration function.

    err_t vcpmonitor3_default_cfg ( vcpmonitor3_t *ctx );

Example key functions :

  • vcpmonitor3_rd_page_0 Read Data From Page 0 function.

    void vcpmonitor3_rd_page_0 ( vcpmonitor3_t *ctx, uint8_t reg, uint8_t *rd_data, uint8_t n_bytes );
  • vcpmonitor3_set_op_mode Set Operation Mode function.

    void vcpmonitor3_set_op_mode ( vcpmonitor3_t *ctx, uint8_t op_mode );
  • vcpmonitor3_read_p Read Power in Watts function.

    float vcpmonitor3_read_p ( vcpmonitor3_t *ctx );

Example Description

VCP Monitor 3 Click show it's full usage by reading current, voltage, power, die temperature and voltage at DVCC using SPI or I2C communication protocol.

The demo application is composed of two sections :

Application Init

Initalizes SPI or I2C driver and sets up the device.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    vcpmonitor3_cfg_t vcpmonitor3_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.
    vcpmonitor3_cfg_setup( &vcpmonitor3_cfg );
    VCPMONITOR3_MAP_MIKROBUS( vcpmonitor3_cfg, MIKROBUS_1 );
    err_t init_flag  = vcpmonitor3_init( &vcpmonitor3, &vcpmonitor3_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( VCPMONITOR3_ERROR == vcpmonitor3_default_cfg ( &vcpmonitor3 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

This example shows capabilities of VCP Monitor 3 Click board by reading current, voltage, power, die temperature and voltage at DVCC and displaying the results via USART terminal.


void application_task ( void )
{
    volt_data = vcpmonitor3_read_v( &vcpmonitor3 );
    log_printf( &logger, " Voltage :         %.2f V \r\n", volt_data );

    cur_data = vcpmonitor3_read_i( &vcpmonitor3 );
    log_printf( &logger, " Current :         %.2f A \r\n", cur_data );

    pow_data = vcpmonitor3_read_p( &vcpmonitor3 );
    log_printf( &logger, " Power :           %.2f W \r\n", pow_data );

    die_temp = vcpmonitor3_read_temp( &vcpmonitor3 );
    log_printf( &logger, " Die Temperature : %.2f C \r\n", die_temp );

    volt_vcc = vcpmonitor3_read_vcc( &vcpmonitor3 );
    log_printf( &logger, " Voltage at DVCC : %.2f V \r\n", volt_vcc );

    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.VCPMonitor3

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.

GPS 5 Click is a compact add-on board that provides users with positioning, navigation, and timing services. This board features the M20050-1, a compact GPS module receiver using the MediaTek MT3333 flash chip, providing a complete GNSS receiver for optimum performance from Antenova. The receiver tracks 3 GNSS constellations concurrently (GPS+Galileo+GLONASS or GPS+Beidou) to considerably enhance location and TTFF (Time-to-first-fix) and has configurable low power modes operating from a 3.3V power supply. In addition to the possibility of using an external antenna, backup power, and various visual indicators, the M20050-1 also has an accurate 0.5ppm TXCO ensuring short TTFF alongside multi-path algorithms, which improves position accuracy in inner-city environments.
