Library Description

Library contains function for write in memory and read from memory.

Key functions:

• void flash6_erase_memory_segment( uint8_t segment, uint32_t start_addr ); - Function for eraseing segment
• void flash6_write_memory_data ( uint32_t addr, uint8_t *data_buf, uint16_t buf_size ); - Function used for writing in memory
• void flash6_read_memory_data ( uint32_t addr, uint8_t *data_buf, uint16_t buf_size ); - Function used for reading from memory

Examples description

The application is composed of three sections :

• System Initialization - Initializes SPI module
• Application Initialization - Initializes driver, resets device and tests communication.
• 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 ( )
{
    uint32_t start_addr;
    uint8_t read_buff[ 50 ];
    uint8_t cnt;
    
    start_addr = 0x002000;

    mikrobus_logWrite( " >>>> Erase sector <<<< ", _LOG_LINE );
    flash6_erase_memory_segment( FLASH6_CMD_SECTOR_ERASE_4KB, start_addr );
    Delay_ms( 500 );
    
    mikrobus_logWrite( " >>>> Write in memory <<<< ", _LOG_LINE );
    mikrobus_logWrite( " >>>> ............... <<<< ", _LOG_LINE );
    flash6_write_memory_data( start_addr, &write_buf[ 0 ], 6 );
    mikrobus_logWrite( " >>>> Read from memory <<<< ", _LOG_LINE );
    flash6_read_memory_data( start_addr, &read_buff[ 0 ], 6 );

    mikrobus_logWrite( " >>>> ", _LOG_TEXT );
    for( cnt = 0; cnt < 6; cnt++ )
    {
        mikrobus_logWrite( &read_buff[ cnt ], _LOG_BYTE );
        mikrobus_logWrite( " ", _LOG_TEXT );
        Delay_ms( 100 );
    }
    mikrobus_logWrite( " <<<< ", _LOG_LINE );
    mikrobus_logWrite( "---------------------------", _LOG_LINE );
    
    Delay_ms( 2000 );
}

Other mikroE Libraries used in the example:

• SPI Library
• Conversions Libray

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.
