SolidSwitch 7 Click

SolidSwitch 7 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 : Stefan Filipovic
• Date : May 2025.
• Type : ADC/I2C type

Software Support

Example Description

This example demonstrates the use of the SolidSwitch 7 Click board by periodically enabling and disabling the output channel while monitoring and logging the load current.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.SolidSwitch7

Example Key Functions

• solidswitch7_cfg_setup This function initializes Click configuration structure to initial values.

void solidswitch7_cfg_setup ( solidswitch7_cfg_t *cfg );

• solidswitch7_init This function initializes all necessary pins and peripherals used for this Click board.

err_t solidswitch7_init ( solidswitch7_t *ctx, solidswitch7_cfg_t *cfg );

• solidswitch7_output_enable This function sets the IN0 pin to high logic level to enable the output stage.

void solidswitch7_output_enable ( solidswitch7_t *ctx );

• solidswitch7_output_disable This function sets the IN0 pin to low logic level to disable the output stage.

void solidswitch7_output_disable ( solidswitch7_t *ctx );

• solidswitch7_read_current This function reads the analog voltage from the diagnostic output and calculates the load current.

err_t solidswitch7_read_current ( solidswitch7_t *ctx, float *current );

Application Init

Initializes the logger and the Click board, enables analog diagnostics and automatic restart features.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    solidswitch7_cfg_t solidswitch7_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.
    solidswitch7_cfg_setup( &solidswitch7_cfg );
    SOLIDSWITCH7_MAP_MIKROBUS( solidswitch7_cfg, MIKROBUS_POSITION_SOLIDSWITCH7 );
    err_t init_flag = solidswitch7_init( &solidswitch7, &solidswitch7_cfg );
    if ( ( ADC_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    solidswitch7_an_diag_enable ( &solidswitch7 );
    solidswitch7_auto_rst_enable ( &solidswitch7 );
    
    log_info( &logger, " Application Task " );
}

Application Task

Alternately enables and disables the output every few seconds, and logs the measured current in each state using the USB UART.

void application_task ( void )
{
    float current = 0;
    log_printf( &logger, " Enable VOUT\r\n" );
    solidswitch7_output_enable ( &solidswitch7 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    if ( SOLIDSWITCH7_OK == solidswitch7_read_current ( &solidswitch7, &current ) ) 
    {
        log_printf( &logger, " Current : %.3f A\r\n\n", current );
    }
    Delay_ms ( 1000 );
    log_printf( &logger, " Disable VOUT\r\n" );
    solidswitch7_output_disable ( &solidswitch7 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    if ( SOLIDSWITCH7_OK == solidswitch7_read_current ( &solidswitch7, &current ) ) 
    {
        log_printf( &logger, " Current : %.3f A\r\n\n", current );
    }
    Delay_ms ( 1000 );
}

Note

Ensure proper load and supply are connected to observe current change during output toggling.

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.
