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.

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.
This library contains API for EEPROM 11 Click driver.
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 );
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 );
This is an example that demonstrates the use of the EEPROM 11 Click board.
The demo application is composed of two sections :
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 " );
}
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.

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.
