The Atmega32 microcontroller consists of two primary memory spaces: the Data Memory and the Program Memory, along with an additional EEPROM Memory designated for data storage. This EEPROM Memory is non-volatile, contributing to the controller’s three distinct memory spaces, all of which exhibit linear and regular properties. The EEPROM memory space stores a maximum of […]

Ethernet has traditionally been a quite complex interface. All Ethernet chips until today had 100 pins or more, where difficult to find in small quantities and difficult to use from a small microcontroller with little memory. Microchip has changed the world with their new ENC28J60 Ethernet chip! The ENC28J60 is a small chip with 28

Introduction The I2C is a multimaster, multislave serial single-ended computer bus and was invented by Philips in 1982. The atmel microcontrollers use a compatible to I2C serial bus that is named TWI (Two Wire Interface). The TWI supports serial communication at 100 kHz and 400 kHz. The master and slave devices that are connected to TWI bus
