Ammeter Click

Ammeter 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.

Click Library

• Author : Jovan Stajkovic
• Date : Dec 2019.
• Type : SPI type

Software Support

Example Description

Demo app measures and displays current by using Ammeter Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ammeter

Example Key Functions

• ammeter_cfg_setup Config Object Initialization function.

void ammeter_cfg_setup ( ammeter_cfg_t *cfg );

• ammeter_init Initialization function.

err_t ammeter_init ( ammeter_t *ctx, ammeter_cfg_t *cfg );

• ammeter_amperage Function is used to measure amperage of a power consumer connected to the Click board.

float ammeter_amperage ( ammeter_t *ctx );

Application Init

Initalizes SPI, LOG and Click drivers.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ammeter_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_printf( &logger, "---- Application Init ----\r\n" );

    //  Click initialization.

    ammeter_cfg_setup( &cfg );
    AMMETER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ammeter_init( &ammeter, &cfg );
    log_printf( &logger, "-----------------------\r\n" );
    log_printf( &logger, "    Ammeter  Click     \r\n" );
    log_printf( &logger, "-----------------------\r\n" );
}

Application Task

This is an example that shows the capabilities of the Ammeter Click by measuring amperage in miliampers. Ammeter Click board can be used to saftly measure current up to 1A both AC and DC, in the case of AC, for peak to peak value.

void application_task ( void )
{
    amperage = ammeter_amperage( &ammeter );
    log_printf( &logger, " Current: %.2f mA \r\n", amperage );
    
    log_printf( &logger, "-----------------------\r\n" );
    Delay_ms ( 1000 );
}

Note

It is important to notice that this Click board has its' own electronic circuit, and may not be powered from the same source which we are measuring. Result will not be correct in that case.

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.
