Flash 3 Click

Flash 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.

Application Init

Initalizes device, Flash 3 Click board and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    flash3_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_info( &logger, "---- Application Init ----" );

    flash3_cfg_setup( &cfg );
    FLASH3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    flash3_init( &flash3, &cfg );

    Delay_ms ( 100 );
    log_printf( &logger, "------------------- \r\n" );
    log_printf( &logger, "  Flash  3  Click  \r\n" );
    log_printf( &logger, "-------------------\r\n" );
    flash3_setting( &flash3 );
    Delay_ms ( 100 );
    log_printf( &logger, "   Initialized     \r\n" );
    log_printf( &logger, "------------------- \r\n" );
}

Application Task

This is an example that shows the capabilities of the Flash 3 Click by writing into memory array of a Flash 3 Click board and reading same data from memory array.

void application_task ( void )
{
    char val_in[ 8 ] = { 0x4D, 0x49, 0x4B, 0x52, 0x4F, 0x45, 0x00 };
    char val_out[ 8 ] = { 0 };

    log_printf( &logger, "\r\n ____________________ \r\n" );
    log_printf( &logger, "Begin demonstration! \r\n\r\n" );
    
    
    log_printf( &logger, "Writing : %s\r\n", val_in );
    flash3_write( &flash3, 0x000000, &val_in[ 0 ], 6 );
    Delay_ms ( 100 );
    log_printf( &logger, "------------------ \r\n" );

    log_printf( &logger, "Reading : %s\r\n", val_in );
    flash3_normal_read( &flash3, 0x000000, &val_in[ 0 ], 6 );
    Delay_ms ( 100 );
    log_printf( &logger, "------------------ \r\n" );

    log_printf( &logger, "Erasing... \r\n" );
    flash3_sector_erase( &flash3, 0x000000 );
    Delay_ms ( 300 );
    log_printf( &logger, "Erased!" );
    Delay_ms ( 100 );
    log_printf( &logger, "------------------ \r\n"  );

    log_printf( &logger, "Reading : %s\r\n", val_out );
    flash3_fast_read( &flash3, 0x000000, &val_out[ 0 ], 6 );
    Delay_ms ( 100 );
    log_printf( &logger, "------------------ \r\n" );

    log_printf( &logger, "Demonstration over!" );
    log_printf( &logger, "\r\n ___________________ \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    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.
