Flash 3 Click Board

We provide a library for the Flash 3 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

The package can be downloaded/installed directly from compilers IDE (recommended), or downloaded from our LibStock, or found on mikroE GitHub account.

Library Description

This library contains an API for the Flash 3 Click Board™ driver.

Standard key functions :

• Config Object Initialization function.

  void flash3_cfg_setup ( flash3_cfg_t *cfg );

• Initialization function.

  FLASH3_RETVAL flash3_init ( flash3_t ctx, flash3_cfg_t cfg );

• Generic transfer function.

  void flash3_generic_transfer ( flash3_t ctx, spi_master_transfer_data_t block );

Example key functions :

• Pause function.

  void flash3_pause ( flash3_t *ctx );

• Unpause function.

  void flash3_unpause ( flash3_t *ctx );

• Unpause function.

  void flash3_unpause ( flash3_t *ctx );

Example Description

This application adding more flash memory.

Application Task

This is an example that shows the capabilities of the Flash 3 click by writing into the memory array of the Flash 3 Click Board™ and reading the same data from the 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( 5000 );
}  

The full application code, and ready to use projects can be installed directly from compilers IDE (recommended) or found on the LibStock page or mikroE GitHub account.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Flash3

Additional Notes and Information

Depending on the development board you are using, you may need a USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
