VCP Monitor 2 Click

VCP Monitor 2 Click is a three-channel, high-side current and bus voltage monitor with alert indication function ensuring the intended application works within desired operating conditions. Featured chip INA3221-Q1, by Texas Instruments, monitors both shunt voltage drops and bus supply voltages, in addition to having programmable conversion times and averaging modes for these signals.

Software Support

We provide a library for the Vcpmonitor2 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 Vcpmonitor2 Click driver.

Standard key functions :

• Config Object Initialization function.

  void vcpmonitor2_cfg_setup ( vcpmonitor2_cfg_t *cfg );

• Initialization function.

  VCPMONITOR2_RETVAL vcpmonitor2_init ( vcpmonitor2_t ctx, vcpmonitor2_cfg_t cfg );

Example key functions :

• Get Manufacture ID.

  uint16_t vcpmonitor2_get_manifacture_id ( vcpmonitor2_t *ctx );

• Get DIE ID.

  uint16_t vcpmonitor2_get_die_id ( vcpmonitor2_t *ctx );

• Get BUS voltage in mV.

  float vcpmonitor2_get_bus_voltage ( vcpmonitor2_t *ctx, uint8_t channel );

Examples Description

VCP Monitor 2 Click is a three-channel, high-side current and bus voltage monitor with alert indication function ensuring the intended application works within desired operating conditions.

The demo application is composed of two sections :

Application Init

Initiaizes the driver, and checks the communication by reading the manufacture device ID. After that, performs the device default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    vcpmonitor2_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.

    vcpmonitor2_cfg_setup( &cfg );
    VCPMONITOR2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    vcpmonitor2_init( &vcpmonitor2, &cfg );

    check_id = vcpmonitor2_get_manifacture_id( &vcpmonitor2 );
    if ( check_id == VCPMONITOR2_DEF_MANUFACTURE_ID )
    {
        log_printf( &logger, ">> Manufacture ID: 0x%.4X\r\n", check_id );
    }
    else
    {
        log_error( &logger, " WRONG ID READ! " );
        log_printf( &logger, "Please restart your system.\r\n" );
        for ( ; ; );
    }

    vcpmonitor2_default_cfg( &vcpmonitor2 );
}

Application Task

Displays the voltage, current, and power detected from channel 1 on the USB UART every 2 seconds. It also displays the status of alert indicators.

void application_task ( void )
{
    log_printf( &logger, ">> CHANNEL 1 <<\r\n" );
    display_channel_data( VCPMONITOR2_CHANNEL_1 );

    display_alert_status( );
    log_printf( &logger, "--------------------------\r\n" );

    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.Vcpmonitor2

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.
