DIGI Isolator 2 Click

DIGI Isolator 2 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 example demonstrates the use of DIGI Isolator 2 Click board by reading and displaying the state of 8 digital input channels.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.DIGIIsolator2

Example Key Functions

• digiisolator2_cfg_setup Config Object Initialization function.

void digiisolator2_cfg_setup ( digiisolator2_cfg_t *cfg );

• digiisolator2_init Initialization function.

err_t digiisolator2_init ( digiisolator2_t *ctx, digiisolator2_cfg_t *cfg );

• digiisolator2_default_cfg Click Default Configuration function.

err_t digiisolator2_default_cfg ( digiisolator2_t *ctx );

• digiisolator2_enable_output This function enables output by setting the EN pin to high state.

void digiisolator2_enable_output ( digiisolator2_t *ctx );

• digiisolator2_disable_output This function disables output by setting the EN pin to low state.

void digiisolator2_disable_output ( digiisolator2_t *ctx );

• digiisolator2_read_inputs This function reads all inputs state via the selected driver interface.

err_t digiisolator2_read_inputs ( digiisolator2_t *ctx, uint8_t *data_out );

Application Init

Initializes the driver and enables isolator outputs.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    digiisolator2_cfg_t digiisolator2_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.
    digiisolator2_cfg_setup( &digiisolator2_cfg );
    DIGIISOLATOR2_MAP_MIKROBUS( digiisolator2_cfg, MIKROBUS_1 );
    if ( DIGIISOLATOR2_OK != digiisolator2_init( &digiisolator2, &digiisolator2_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    digiisolator2_enable_output( &digiisolator2 );
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads the state of 8 digital input channels in hex format where MSB represents IN8 and LSB the channel IN1. The results are displayed on the USB UART every 500ms.

void application_task ( void )
{
    uint8_t input_data = 0;
    if ( DIGIISOLATOR2_OK == digiisolator2_read_inputs ( &digiisolator2, &input_data ) )
    {
        log_printf( &logger, " INPUT: 0x%.2X\r\n\n", ( uint16_t ) input_data );
        Delay_ms ( 500 );
    }
}

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.
