VCT Monitor Click

VCT Monitor Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This is an example which demonstrates the use of VCT Monitor Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.VCTMonitor

Example Key Functions

• vctmonitor_cfg_setup Config Object Initialization function.

void vctmonitor_cfg_setup ( vctmonitor_cfg_t *cfg );

• vctmonitor_init Initialization function.

err_t vctmonitor_init ( vctmonitor_t *ctx, vctmonitor_cfg_t *cfg );

• vctmonitor_get_status Gets status value.

uint8_t vctmonitor_get_status ( vctmonitor_t *ctx );

• vctmonitor_read_temperature Get temperature function

float vctmonitor_read_temperature ( vctmonitor_t *ctx );

• vctmonitor_read_current Current function

float vctmonitor_read_current ( vctmonitor_t *ctx );

Application Init

Initialization driver enables the USB uart terminal and I2C.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    vctmonitor_cfg_t vctmonitor_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.
    vctmonitor_cfg_setup( &vctmonitor_cfg );
    VCTMONITOR_MAP_MIKROBUS( vctmonitor_cfg, MIKROBUS_1 );
    err_t init_flag = vctmonitor_init( &vctmonitor, &vctmonitor_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

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

Application Task

Reads temperature, current value, and differential voltage every 4 seconds.

void application_task ( void ) 
{
    float temperature;
    float voltage;
    float current;
    
    voltage = vctmonitor_read_voltage_differential( &vctmonitor );
    log_printf( &logger, " Voltage    : %.2f mV \r\n", voltage );

    current = vctmonitor_read_current( &vctmonitor );
    log_printf( &logger, " Current    : %.2f mA \r\n", current );

    temperature = vctmonitor_read_temperature( &vctmonitor );
    log_printf( &logger, " Temperature: %.2f C \r\n", temperature );

    log_printf( &logger, "- - - - - - - - - - - -\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );     
}

Note

We used the next sets for the test: - Power supply - 4V - Current (Load) - 0A to 3A - The temperature reads from the external MMBT3904 sensor

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
