MRAM Click

MRAM 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.

• Date : Dec 2019.
• Type : SPI type

Software Support

Example Description

This example writes and reads from the Mram Click and displays it on the terminal.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.MRAM

Example Key Functions

• mram_cfg_setup Config Object Initialization function.

void mram_cfg_setup ( mram_cfg_t *cfg ); 

• mram_init Initialization function.

err_t mram_init ( mram_t *ctx, mram_cfg_t *cfg );

• mram_default_cfg Click Default Configuration function.

void mram_default_cfg ( mram_t *ctx );

• mram_write_data_bytes Function writes n bytes of data from the buffer.

void mram_write_data_bytes ( mram_t *ctx, const uint16_t address, uint8_t *buffer, const uint16_t nBytes);

• mram_read_data_bytes Function reads n bytes of data and saves it in buffer.

void mram_read_data_bytes ( mram_t *ctx, const uint16_t address, uint8_t *buffer, const uint16_t n_bytes);

• mram_enable_write_protect Function enables or disables write protect.

void mram_enable_write_protect ( mram_t *ctx, uint8_t state);

Application Init

Initializes Click driver.

void application_init ( void )
{
    log_cfg_t log_cfg;
    mram_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.

    mram_cfg_setup( &cfg );
    MRAM_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    mram_init( &mram, &cfg );
    mram_default_cfg( &mram );
}

Application Task

Writes 10 bytes of buffer data in memory with start address 0x0001. Then reads 10 bytes from memory with start address 0x0001 and shows result on USB UART.

void application_task ( void )
{
    uint8_t number_bytes_write;
    uint8_t number_bytes_read;
    uint16_t i;
    uint8_t data_write[ 10 ] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
    uint8_t data_read[ 20 ] = { 0 };
    
    number_bytes_write = 10;
    number_bytes_read = 10;

    log_printf( &logger, " Data written!\r\n" );
    mram_write_data_bytes ( &mram, 0x0001, data_write, number_bytes_write );
    
    log_printf( &logger, " Read data:\r\n" );
    mram_read_data_bytes ( &mram, 0x0001, data_read, number_bytes_read );
    
    for ( i = 0; i < number_bytes_read; i++ )
    {
        log_printf( &logger, "%d ", ( uint16_t )data_read[ i ] );
    }
    
    log_printf( &logger, "\n" );

    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.
