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.

Click library

  • Author : Stefan Ilic
  • Date : Aug 2023.
  • Type : I2C type

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 :

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;
eeprom11_cfg_t eeprom11_cfg;
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;
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.
