EEPROM 3 click

EEPROM 3 click provides 2 Mbit (2,097,152 bits) of Electrically Erasable Programmable Read Only Memory, organized in bytes. In other words, this click boardâ„¢ is an EEPROM memory medium with the capacity of 256 KB. The used EEPROM module has outstanding endurance, with 1,000,000 write cycles and data retention period of over 100 years.

Click library

Software Support

We provide a library for the Eeprom3 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Eeprom3 Click driver.

Standard key functions :

Example key functions :

Examples Description

This example demonstrates the process of reading and writing to the EEPROM.

The demo application is composed of two sections :

Application Init

Initializes EEPROM 3 driver.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
EEPROM3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
eeprom3_init( &eeprom3, &cfg );
}

Application Task

Writing data to EEPROM, reading that data and displaying it via UART

void application_task ( void )
{
eeprom3_write_page( &eeprom3, 0x0423, text, 6 );
log_printf( &logger, "Writing Mikroe to EEPROM 3 click\r\n" );
Delay_ms( 1000 );
eeprom3_read( &eeprom3, 0x0423, mem_value, 6 );
log_printf( &logger, "Data read: %s\r\n", mem_value );
Delay_ms( 1000 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
