SPI Isolator 6 Click

SPI Isolator 6 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 SPI Isolator 6 Click board by reading the device ID of the connected Accel 22 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.SPIIsolator6

Example Key Functions

• spiisolator6_cfg_setup Config Object Initialization function.

void spiisolator6_cfg_setup ( spiisolator6_cfg_t *cfg );

• spiisolator6_init Initialization function.

err_t spiisolator6_init ( spiisolator6_t *ctx, spiisolator6_cfg_t *cfg );

• spiisolator6_generic_write This function writes a desired number of data bytes by using SPI serial interface.

err_t spiisolator6_generic_write ( spiisolator6_t *ctx, uint8_t *data_in, uint8_t in_len );

• spiisolator6_generic_read This function writes and then reads a desired number of data bytes by using SPI serial interface.

err_t spiisolator6_generic_read ( spiisolator6_t *ctx, uint8_t *data_in, uint8_t in_len, uint8_t *data_out, uint8_t out_len );

Application Init

Initializes the driver and logger.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    spiisolator6_cfg_t spiisolator6_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.
    spiisolator6_cfg_setup( &spiisolator6_cfg );
    SPIISOLATOR6_MAP_MIKROBUS( spiisolator6_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == spiisolator6_init( &spiisolator6, &spiisolator6_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads and checks the device ID of the connected Accel 22 Click board, and displays the results on the USB UART approximately once per second.

void application_task ( void )
{
    spiisolator6_get_accel22_device_id ( &spiisolator6 );
    Delay_ms ( 1000 );
}

Note

Make sure to provide VCC power supply on VCC-EXT pin.

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.
