Flash 12 Click

Flash 12 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 Flash 12 Click board by writing specified data to the memory and reading it back.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Flash12

Example Key Functions

• flash12_cfg_setup Config Object Initialization function.

void flash12_cfg_setup ( flash12_cfg_t *cfg );

• flash12_init Initialization function.

err_t flash12_init ( flash12_t *ctx, flash12_cfg_t *cfg );

• flash12_default_cfg Click Default Configuration function.

err_t flash12_default_cfg ( flash12_t *ctx );

• flash12_memory_write This function writes a desired number of data bytes starting to the selected memory address by using SPI serial interface.

err_t flash12_memory_write ( flash12_t *ctx, uint32_t mem_addr, uint8_t *data_in, uint32_t len );

• flash12_memory_read This function reads a desired number of data bytes starting from the selected memory address by using SPI serial interface.

err_t flash12_memory_read ( flash12_t *ctx, uint32_t mem_addr, uint8_t *data_out, uint32_t len );

• flash12_erase_memory This function erases the selected amount of memory which contains the selected address.

err_t flash12_erase_memory ( flash12_t *ctx, uint8_t erase_cmd, uint32_t mem_addr );

Application Init

The initialization of SPI module and log UART. After driver initialization, the app sets the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    flash12_cfg_t flash12_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.
    flash12_cfg_setup( &flash12_cfg );
    FLASH12_MAP_MIKROBUS( flash12_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == flash12_init( &flash12, &flash12_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( FLASH12_ERROR == flash12_default_cfg ( &flash12 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task\r\n" );
}

Application Task

The demo application writes a desired number of bytes to the memory and then verifies if it is written correctly by reading from the same memory location and displaying the memory content. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
    uint8_t data_buf[ 128 ] = { 0 };

    log_printf( &logger, " Memory address: 0x%.6LX\r\n", ( uint32_t ) STARTING_ADDRESS );
    if ( FLASH12_OK == flash12_erase_memory( &flash12, FLASH12_CMD_BLOCK_ERASE_4KB, STARTING_ADDRESS ) )
    {
        log_printf( &logger, " Erase memory block (4KB)\r\n" );
    }
    memcpy( data_buf, DEMO_TEXT_MESSAGE_1, strlen( DEMO_TEXT_MESSAGE_1 ) );
    if ( FLASH12_OK == flash12_memory_write( &flash12, STARTING_ADDRESS, 
                                                       data_buf, 
                                                       sizeof( data_buf ) ) )
    {
        log_printf( &logger, " Write data: %s\r\n", data_buf );
        Delay_ms ( 100 );
    }

    memset( data_buf, 0, sizeof( data_buf ) );
    if ( FLASH12_OK == flash12_memory_read( &flash12, STARTING_ADDRESS, 
                                                      data_buf, 
                                                      sizeof( data_buf ) ) )
    {
        log_printf( &logger, " Read data: %s\r\n\n", data_buf );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
    }

    log_printf( &logger, " Memory address: 0x%.6LX\r\n", ( uint32_t ) STARTING_ADDRESS );
    if ( FLASH12_OK == flash12_erase_memory( &flash12, FLASH12_CMD_BLOCK_ERASE_4KB, STARTING_ADDRESS ) )
    {
        log_printf( &logger, " Erase memory block (4KB)\r\n" );
    }
    memcpy( data_buf, DEMO_TEXT_MESSAGE_2, strlen( DEMO_TEXT_MESSAGE_2 ) );
    if ( FLASH12_OK == flash12_memory_write( &flash12, STARTING_ADDRESS, 
                                             data_buf, sizeof( data_buf ) ) )
    {
        log_printf( &logger, " Write data: %s\r\n", data_buf );
        Delay_ms ( 100 );
    }
    memset( data_buf, 0, sizeof ( data_buf ) );
    if ( FLASH12_OK == flash12_memory_read( &flash12, STARTING_ADDRESS, 
                                            data_buf, sizeof ( data_buf ) ) )
    {
        log_printf( &logger, " Read data: %s\r\n\n", data_buf );
        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.
