e Fuse 3 Click

e Fuse 3 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 : Nenad Filipovic
• Date : Feb 2021.
• Type : SPI type

Software Support

Example Description

This library contains API for the eFuse 3 Click driver. The library contains drivers to enable/disable the device, for reading ADC voltage, overflow status, output and current value [ A ].

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.eFuse3

Example Key Functions

• efuse3_cfg_setup Config Object Initialization function.

void efuse3_cfg_setup ( efuse3_cfg_t *cfg );

• efuse3_init Initialization function.

err_t efuse3_init ( efuse3_t *ctx, efuse3_cfg_t *cfg );

• efuse3_default_cfg Click Default Configuration function.

void efuse3_default_cfg ( efuse3_t *ctx );

• efuse3_get_current e Fuse 3 get current function.

err_t efuse3_get_current ( efuse3_t *ctx, float *current );

• efuse3_get_flag e Fuse 3 get flag function.

uint8_t efuse3_get_flag ( efuse3_t *ctx );

• efuse3_reset e Fuse 3 reset function.

void efuse3_reset ( efuse3_t *ctx );

Application Init

Initializes SPI driver and set default configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;        /**< Logger config object. */
    efuse3_cfg_t efuse3_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.

    efuse3_cfg_setup( &efuse3_cfg );
    EFUSE3_MAP_MIKROBUS( efuse3_cfg, MIKROBUS_1 );
    err_t init_flag  = efuse3_init( &efuse3, &efuse3_cfg );
    if ( init_flag == SPI_MASTER_ERROR ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    efuse3_default_cfg ( &efuse3 );
    log_info( &logger, " Application Task " );
    log_printf( &logger, "---------------------------\r\n" );
    Delay_ms ( 100 );
}

Application Task

This is an example that demonstrates the use of the eFuse 3 Click board. Read and display device status information and current value [ A ]. The eFuse 3 includes an overvoltage clamp the circuit that limits the output voltage during transients but does not shut the unit down, thereby allowing the load circuit to continue its operation. The Electronic Fuse is to limit current and current limit Current limit ( 0.1 A - 1.8 A ) depends on the choice of resistor wired on the Rlimit ( 1 Ohm - 15 Ohm ) connector. For example, for Rlimit resistance of 1 Ohm, current limit is 1 A ( 3.5 Ohm - 0.5 A, 7 Ohm - 0.25 A ). Read details from the ON Semiconductor NIS6150 datasheets.
Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void ) 
{
    log_printf( &logger, " Status  :" );    
    
    if ( efuse3_get_flag( &efuse3 ) == EFUSE3_FLAG_NORMAL_OPERATION ) {
        log_printf( &logger, " Normal operation \r\n" );
    } else {
        log_printf( &logger, " Device OFF \r\n" );

        if ( overflow_status == EFUSE3_OVERFLOW_HIGH ) {
            log_printf( &logger, " Overflow high in the analog input voltage.\r\n" );    
        } else if ( overflow_status == EFUSE3_OVERFLOW_LOW ) {
            log_printf( &logger, " Overflow low in the analog input voltage.\r\n" ); 
        }
        
        efuse3_reset( &efuse3 );
        Delay_ms ( 1000 );
    }
    
    log_printf( &logger, "- - - - - - - - - - - - - - \r\n" );
    efuse3_get_current( &efuse3, &current );
    log_printf( &logger, " Current : %.5f A\r\n", current );
    log_printf( &logger, "---------------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

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.
