EEPROM 11 Click

EEPROM 11 Click is a compact add-on board with a highly reliable, nonvolatile memory solution. This board features the S-34C04AB, an EEPROM for DIMM serial presence detection from ABLIC. The EEPROM is internally organized as 2 pages of 256 words x 8-bit, and a capacity of 4Kbits and is an EE1004-1 JEDEC standard-compliant.

Software Support

We provide a library for the EEPROM 11 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for EEPROM 11 Click driver.

Standard key functions :

• eeprom11_cfg_setup Config Object Initialization function.

  void eeprom11_cfg_setup ( eeprom11_cfg_t *cfg );

• eeprom11_init Initialization function.

  err_t eeprom11_init ( eeprom11_t *ctx, eeprom11_cfg_t *cfg );

• eeprom11_default_cfg Click Default Configuration function.

  err_t eeprom11_default_cfg ( eeprom11_t *ctx );

Example key functions :

• eeprom11_page_write EEPROM 11 page write function.

  err_t eeprom11_page_write ( eeprom11_t *ctx, uint8_t address, uint8_t *data_in );

• eeprom11_clear_page EEPROM 11 page clear function.

  err_t eeprom11_clear_page ( eeprom11_t *ctx, uint8_t address );

• eeprom11_set_page_addr EEPROM 11 set page address function.

  err_t eeprom11_set_page_addr ( eeprom11_t *ctx, uint8_t page_addr );

Example Description

This is an example that demonstrates the use of the EEPROM 11 Click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and USB UART logging, disables write protection.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    eeprom11_cfg_t eeprom11_cfg;  /**< Click config object. */

    /** 
     * 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.
    eeprom11_cfg_setup( &eeprom11_cfg );
    EEPROM11_MAP_MIKROBUS( eeprom11_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == eeprom11_init( &eeprom11, &eeprom11_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( EEPROM11_ERROR == eeprom11_default_cfg ( &eeprom11 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Writes a desired number of data bytes to the EEPROM 11 memory into a specified address, and verifies that it is written correctly by reading from the same memory location.

void application_task ( void ) 
{
    err_t error_flag = EEPROM11_OK;
    uint8_t rx_data[ 16 ] = { 0 };
    uint8_t tx_data[ 16 ] = TX_DATA;

    eeprom11_clear_page( &eeprom11, MEMORY_ADDRESS );
    Delay_ms ( 1000 );
    error_flag = eeprom11_page_write( &eeprom11, MEMORY_ADDRESS, tx_data );
    if ( EEPROM11_OK == error_flag )
    {
        log_printf( &logger, " Write data: %s \r\n", tx_data );
    }
    else
    {
        log_error( &logger, " Write operation failed!!! " );
    }
    Delay_ms ( 1000 );

    error_flag = eeprom11_generic_read( &eeprom11, MEMORY_ADDRESS, rx_data, 15 );
    if ( EEPROM11_OK == error_flag )
    {
        log_printf( &logger, "Read data: %s \r\n", rx_data );
    }
    else
    {
        log_error( &logger, " Write operation failed!!! " );
    }
    log_printf( &logger, " - - - - - - - - - - - \r\n" );

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.EEPROM11

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. UART terminal is available in all MikroElektronika compilers.
