MCU Datalogger with memory and clock

Project Overview:

Project Name:
MCU Data Logger for ATmega328-AU
Author: Majed Alharbi [ Majed Dev ]
URL: https://github.com/DevMajed/Dattalogger_Board.git

Objective :
The MCU Data Logger is designed to log data from various sensors or peripherals connected to an ATmega328-AU microcontroller.
The project incorporates features such as external EEPROM memory (24LC1025), a real-time clock (DS1337S), and essential connectors for communication and programming.

Block Diagram / Circuit Schematic :

ATmega328-AU:
Main microcontroller responsible for data processing, sensor interfacing, and overall control of the system.

EEPROM (24LC1025):
External EEPROM memory for storing data logs, and it rovides non-volatile extended storage capacity.

Real-Time Clock (DS1337S):
Provides accurate timekeeping for timestamping data logs.

Real time Crystal Oscillator:
32.768 kHz: Connected to DS1337S for precise real-time tracking.

High speed Crystal Oscillator :
16 MHz, Connected to Pins B6 and B7 of the AVR, with capacitors for stable clock operation.

Connectors:
UART: For serial communication.
ICSP: In-Circuit Serial Programming for firmware updates.
I2C: General-purpose I2C communication.
GPIO: General-purpose input/output for additional peripherals.

Interactions between Blocks:

The ATmega328-AU communicates with the EEPROM over the I2C bus, storing and retrieving data logs.
The DS1337S sends real-time information to the ATmega328-AU, allowing accurate timestamping of data.
The 16 MHz crystal oscillator provides the main clock signal for the ATmega328-AU, ensuring proper execution of instructions.
Connectors facilitate external communication and programming, enhancing the project's versatility.
