AVR Microcontroller and Arduino Tutorial

What is the Minimum System on the Microcontroller?

The minimum system circuit of a microcontroller is a series of minimal so the microcontroller can work. ATmegga AVR chip is equipped with an internal oscillator and thus no need external crystal for CPU clock source in order to save costs. AVR microcontroller minimum system is very simple, just connect the VCC and AVCC to […]

Atmega8 Datasheet and the Explanation of The Input Output Pin Features

In this article described the hardware features of the AVR ATMega atmega 8 that is devoted to the type of PDIP, so for other types (QFN / MLF, TQPF) please refer to the specific datasheet only. In addition to functioning as an input/output pins, a pin on AVR microcontroller can concurrently as other functions. For […]

AVR Microcontroller Architecture

AVR microcontroller has some parts that are divided into: ALU (Arithmetic Logic Unit) is a processor for executing the program code that is appointed by the counter program. Program memory is a flash memory to store programs in the form of a memory address and program code in the memory address. Program Counter (PC) is […]
