EEPROM 14 Click

EEPROM 14 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 : Stefan Filipovic
• Date : Sep 2025.
• Type : I2C type

Software Support

Example Description

This example demonstrates basic read and write operations on the EEPROM 14 Click. The application writes predefined text messages into memory, then reads them back and logs the results for verification.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.EEPROM14

Example Key Functions

• eeprom14_cfg_setup This function initializes Click configuration structure to initial values.

  void eeprom14_cfg_setup ( eeprom14_cfg_t *cfg );

• eeprom14_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t eeprom14_init ( eeprom14_t *ctx, eeprom14_cfg_t *cfg );

• eeprom14_write_memory This function writes a sequence of bytes to the device memory over I2C, starting at the selected 16-bit address.

  err_t eeprom14_write_memory ( eeprom14_t *ctx, uint16_t address, uint8_t *data_in, uint8_t len );

• eeprom14_read_memory This function reads a sequence of bytes from the device memory over I2C, starting at the selected 16-bit address.

  err_t eeprom14_read_memory ( eeprom14_t *ctx, uint16_t address, uint8_t *data_out, uint16_t len );

Application Init

Initializes the logger, configures and initializes the EEPROM 14 Click.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    eeprom14_cfg_t eeprom14_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    eeprom14_cfg_setup( &eeprom14_cfg );
    EEPROM14_MAP_MIKROBUS( eeprom14_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == eeprom14_init( &eeprom14, &eeprom14_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Writes and reads text messages from EEPROM memory, displaying the stored values via the UART logger.

void application_task ( void )
{
    uint8_t data_buf[ EEPROM14_MEM_PAGE_SIZE + 1 ] = { 0 };
 
    log_printf ( &logger, " Memory address: 0x%.4X\r\n", STARTING_ADDRESS );
    memcpy ( data_buf, DEMO_TEXT_MESSAGE_1, strlen ( DEMO_TEXT_MESSAGE_1 ) );
    if ( EEPROM14_OK == eeprom14_write_memory ( &eeprom14, STARTING_ADDRESS, data_buf, EEPROM14_MEM_PAGE_SIZE ) )
    {
        log_printf ( &logger, " Write data: %s\r\n", data_buf );
    }
    Delay_ms ( 100 );
    memset ( data_buf, 0, sizeof ( data_buf ) );
    if ( EEPROM14_OK == eeprom14_read_memory ( &eeprom14, STARTING_ADDRESS, data_buf, EEPROM14_MEM_PAGE_SIZE ) )
    {
        log_printf ( &logger, " Read data: %s\r\n\n", data_buf );
    }
    Delay_ms ( 1000 );
    
    log_printf ( &logger, " Memory address: 0x%.4X\r\n", STARTING_ADDRESS );
    memcpy ( data_buf, DEMO_TEXT_MESSAGE_2, strlen ( DEMO_TEXT_MESSAGE_2 ) );
    if ( EEPROM14_OK == eeprom14_write_memory ( &eeprom14, STARTING_ADDRESS, data_buf, EEPROM14_MEM_PAGE_SIZE ) )
    {
        log_printf ( &logger, " Write data: %s\r\n", data_buf );
    }
    Delay_ms ( 100 );
    memset ( data_buf, 0, sizeof ( data_buf ) );
    if ( EEPROM14_OK == eeprom14_read_memory ( &eeprom14, STARTING_ADDRESS, data_buf, EEPROM14_MEM_PAGE_SIZE ) )
    {
        log_printf ( &logger, " Read data: %s\r\n\n", data_buf );
    }
    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.
