Click library

• Author : MikroE Team
• Date : dec 2019.
• Type : SPI type

Software Support

We provide a library for the Flash3 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Flash3 Click 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 );

Examples Description

This applicaion adding more flash memory.

The demo application is composed of two sections :

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 );
}  

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need 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.
