FRAM 3 Click

FRAM 3 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.

Click Library

• Author : MikroE Team
• Date : Dec 2019.
• Type : I2C type

Software Support

Example Description

This application writes data in memmory and reads data from memmory.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.FRAM3

Example Key Functions

• fram3_cfg_setup Config Object Initialization function.

void fram3_cfg_setup ( fram3_cfg_t *cfg );

• fram3_init Initialization function.

err_t fram3_init ( fram3_t *ctx, fram3_cfg_t *cfg );

• fram3_read_free_access_memory Memory read function.

uint8_t fram3_read_free_access_memory ( fram3_t *ctx, uint8_t start_addr, uint8_t *data_buf, uint8_t n_buf_size );

• fram3_write_free_access_memory Memory write function.

uint8_t fram3_write_free_access_memory ( fram3_t *ctx, uint8_t start_addr, uint8_t *data_buf, uint8_t n_buf_size );

Application Init

Initializes device init

void application_init ( void )
{
    log_cfg_t log_cfg;
    fram3_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.

    fram3_cfg_setup( &cfg );
    FRAM3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    fram3_init( &fram3, &cfg );
}

Application Task

Writes and then reads data from memory

void application_task (  )
{
    static char write_data[ 7 ] = { 'M', 'i', 'k', 'r', 'o', 'E', 0 };
    static char read_data[ 7 ];
    static uint8_t cnt;
    static uint8_t status_check;

    log_printf( &logger, " - Writing...  \r\n" );
    Delay_ms ( 500 );
    status_check = fram3_write_free_access_memory( &fram3, 0x00, &write_data[ 0 ], 7 );
    if ( status_check == FRAM3_ERROR )
    {
        log_printf( &logger, " - ERROR WRITING!!! \r\n" );
        for ( ; ; );
    }
    
    log_printf( &logger, " - Reading... \r\n" );
    Delay_ms ( 500 );
    status_check = fram3_read_free_access_memory( &fram3, 0x00, &read_data[ 0 ], 7 );
    if ( status_check == FRAM3_ERROR )
    {
        log_printf( &logger, " - ERROR READING!!! \r\n" );
        for ( ; ; );
    }

    for ( cnt = 0; cnt < 7; cnt++ )
    {
        log_printf( &logger, " %c ", read_data[ cnt ] );
        Delay_ms ( 100 );
    }
    log_printf( &logger, " \r\n " );
    Delay_ms ( 1000 );
    log_printf( &logger, "__________________________\r\n " );
    Delay_ms ( 500 );
}

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.
