MRAM 2 Click

MRAM 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This example demonstrates the use of MRAM 2 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Mram2

Example Key Functions

• mram2_cfg_setup Config Object Initialization function.

void mram2_cfg_setup ( mram2_cfg_t *cfg ); 

• mram2_init Initialization function.

err_t mram2_init ( mram2_t *ctx, mram2_cfg_t *cfg );

• mram2_wren Write Enable function

void mram2_wren ( mram2_t *ctx );

• mram2_read Read Data Bytes function

void mram2_read ( mram2_t *ctx, uint32_t mem_adr, uint8_t *rd_data, uint8_t n_bytes );

• mram2_write Write Data Bytes function

void mram2_write ( mram2_t *ctx, uint32_t mem_adr, uint8_t *wr_data, uint8_t n_bytes );

Application Init

Initializes the driver, sets the write protect and disables the hold signal.

void application_init ( void )
{
    log_cfg_t log_cfg;
    mram2_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 ----" );

    //  Click initialization.

    mram2_cfg_setup( &cfg );
    MRAM2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    mram2_init( &mram2, &cfg );

    log_printf( &logger, "------------------- \r\n" );
    log_printf( &logger, "   MRAM 2 Click     \r\n" );
    log_printf( &logger, "------------------- \r\n" );
    mram2_write_protect( &mram2, MRAM2_WP_ENABLE );
    mram2_hold( &mram2, MRAM2_HLD_DISABLE );
    log_printf( &logger, "   Initialized      \r\n" );
    log_printf( &logger, "------------------- \r\n" );
    Delay_ms ( 100 );
}

Application Task

Writes "MikroE" into the first 6 memory locations, and then reads it back and displays it to the USB UART approximately every 5 seconds.

void application_task ( void )
{
    mram2_wren( &mram2 );
    log_printf( &logger, "Write enabled!\r\n" );
    Delay_ms ( 100 );
    log_printf( &logger, "Writing \"%s\" to memory...\r\n", val_in );
    mram2_write( &mram2, 0x000000, &val_in[ 0 ], 6 );
    Delay_ms ( 100 );
    mram2_wrdi ( &mram2 );
    log_printf( &logger, "Write disabled!\r\n" );
    Delay_ms ( 100 );
    mram2_read ( &mram2, 0x000000, &val_out[ 0 ], 6 );
    log_printf( &logger, "Read data : %s\r\n", val_out );
    
    log_printf( &logger, "-------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
