Click library

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

Software Support

We provide a library for the Flash5 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 Flash5 Click driver.

Standard key functions :

• Config Object Initialization function.

  void flash5_cfg_setup ( flash5_cfg_t *cfg );

• Initialization function.

  FLASH5_RETVAL flash5_init ( flash5_t ctx, flash5_cfg_t cfg );

Example key functions :

• Function for setting page read

  void flash5_page_read ( flash5_t *ctx, uint16_t page_num );

• Function for loading one page

  void flash5_page_load_memory ( flash5_t ctx, uint16_t column_addr, uint8_t data_buf, uint16_t buf_size );

• Function for writing status data

  void flash5_write_status_data ( flash5_t *ctx, uint8_t status_cmd, uint8_t status_addr, uint8_t status_data );

Examples Description

This application is for storing mass storage.

The demo application is composed of two sections :

Application Init

Initializes driver, resets device, erasing one page of memory, tests communication and configures device.

void application_init ( void )
{
    log_cfg_t log_cfg;
    flash5_cfg_t cfg;
    uint8_t device_check = 0;

    /** 
     * 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.

    flash5_cfg_setup( &cfg );
    FLASH5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    flash5_init( &flash5, &cfg );

    log_printf( &logger, " - Reseting device... \r\n" );

    flash5_software_reset( &flash5 );
    Delay_ms ( 1000 );

    log_printf( &logger, " - Erasing memory... \r\n" );   

    flash5_send_cmd( &flash5, FLASH5_CMD_WRITE_ENABLE );
    flash5_erase_page_data( &flash5, 0x0001 );

    device_check = flash5_device_id_check( &flash5 );

    if ( device_check == FLASH5_DEVICE_OK )
    {
        log_printf( &logger, " - Device OK \r\n" );  
    }
    else
    {
        log_printf( &logger, " - Device Error \r\n" );  
        for( ; ; );
    }
    Delay_ms ( 100 );

    log_printf( &logger, " - Configuring device \r\n" );  

    flash5_write_status_data( &flash5, FLASH5_CMD_WRITE_REG_STATUS1, FLASH5_REG_STATUS_1, FLASH5_RS1_WRITE_PROTECTION_DISABLE | 
                                                                                          FLASH5_RS1_SRP1_ENABLE );
    flash5_write_status_data( &flash5, FLASH5_CMD_WRITE_REG_STATUS1, FLASH5_REG_STATUS_1, FLASH5_RS2_PAGE_READ_MODE );
    Delay_ms ( 1000 );

    log_printf( &logger, "***** App init ***** \r\n" );
    log_printf( &logger, "------------------- \r\n" );
    Delay_ms ( 500 );
}

Application Task

Writes "MikroE" to device memory and then reads it and sends it to log.

void application_task ( )
{
    char read_buf[ 6 ];
    uint8_t n_counter;

    flash5_send_cmd( &flash5, FLASH5_CMD_WRITE_ENABLE );
    flash5_page_load_memory( &flash5, 0x000A, &write_buf[ 0 ], 6 );
    flash5_page_read_memory( &flash5, 0x000A, &read_buf[ 0 ], 6 );

    for( n_counter = 0; n_counter < 6; n_counter++ )
    {
        log_printf( &logger, " %c ", &read_buf[ n_counter ] );
        Delay_ms ( 100 );
    }

    log_printf( &logger, " \r\n" );
    log_printf( &logger, "------------------- \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.Flash5

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.
