Click library

• Author : MikroE Team
• Date : Feb 2020.
• Type : SPI type

Software Support

We provide a library for the Flash6 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 Flash6 Click driver.

Standard key functions :

• Config Object Initialization function.

void flash6_cfg_setup ( flash6_cfg_t *cfg );

• Initialization function.

FLASH6_RETVAL flash6_init ( flash6_t *ctx, flash6_cfg_t *cfg );

Example key functions :

• Function used for writing in memory

void flash6_write_memory_data ( flash6_t *ctx, uint32_t addr, uint8_t *data_buf, uint16_t buf_size );

• Function used for reading from memory

void flash6_read_memory_data ( flash6_t *ctx, uint32_t addr, uint8_t *data_buf, uint16_t buf_size );

• Function for eraseing segment

void flash6_erase_memory_segment( flash6_t *ctx, uint8_t segment, uint32_t start_addr );

Examples Description

This application writes in memory and reads from memory.

The demo application is composed of two sections :

Application Init

Initializes driver, resets device and tests communication.

void application_init ( void )
{
    log_cfg_t log_cfg;
    flash6_cfg_t cfg;

    uint8_t manufacture_id;
    uint8_t device_id;

    /** 
     * 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.

    flash6_cfg_setup( &cfg );
    FLASH6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    flash6_init( &flash6, &cfg );

    flash6_software_reset( &flash6 );
    Delay_ms( 100 );

    flash6_get_manufacture_device_id( &flash6, &manufacture_id, &device_id );
    log_printf( &logger, "\r\n ------> MANUFACTURE ID: 0x%x \r\n", manufacture_id );
    log_printf( &logger, " ------> DEVICE ID: 0x%x \r\n \r\n", device_id );
    Delay_ms( 1000 );
}
  

Application Task

Clears the memory sector, writes "MikroE" to device memory and then reads it and sends it to log every 2 sec.

void application_task ( void )
{
    uint32_t start_addr;
    char read_buff[ 50 ];
    uint8_t cnt;
    
    start_addr = 0x002000;

    log_printf( &logger, " ---> Erase sector  \r\n" );
    flash6_erase_memory_segment( &flash6, FLASH6_CMD_SECTOR_ERASE_4KB, start_addr );
    Delay_ms( 500 );
    
    log_printf( &logger, " ---> Write in memory ... \r\n" );
    flash6_write_memory_data( &flash6, start_addr, &write_buf[ 0 ], 9 );
    log_printf( &logger, " ---> Read from memory \r\n" );
    flash6_read_memory_data( &flash6, start_addr, read_buff, 9 );

    log_printf( &logger, "---->>>> " );
    
    log_printf( &logger, "%s ", read_buff );
    Delay_ms( 100 );
    log_printf( &logger, "----------------------------------\r\n" );
    
    Delay_ms( 2000 );
}

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.Flash6

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.
