What is an ATmega8?

The ATmega8 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega8 achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption ver- sus processing speed.

How do I program ATmega8?

Then we set up the breadboard and connect ATmega8 to Arduino UNO board.

1. Step One: Adding ATmega8 Support to Arduino IDE Using Board Manager.
2. Step Two: Programming Arduino as an ISP (In-system programming)
3. Step Three: Burning Bootloader.
4. Step Four: Setting up the Connections.
5. Step Five: Uploading the Sketch to ATmega8.

How many timers are there in ATmega8?

3 different timers
ATmega8 have 3 different timers, of which the simplest one is TIMER0, with an 8 bit (0-255) resolution.

Which are the inbuilt peripherals of ATmega8 AVR microcontroller?

Internal peripherals.

• Two 8-bit Timer/Counters with Separate Prescalers and Compare Modes.
• One 16-bit Timer/Counter with Separate Prescaler, Compare Mode, and Capture Mode.
• Real Time Counter with Separate Oscillator.
• Four PWM Channels.

What is ATMEGA8 Arduino?

Features: ATmega8 microcontroller (Self Programmable) CAN be used as ARDUINO Board as well as AVR’s 28 PIN ATMEGA8 DEVELOPMENT BOARD. Buit In Power Supply : Input voltage – +7-+12V 14 Digital I/O Pins (6 PWM outputs) 6 Analog Inputs 8k Flash Memory 16Mhz Clock Speed No Need of any Programmer.

What is the difference between ATmega328 and atmega328p?

There is no major functional difference between them except for power. This microcontrollers are mostly used in Arduino’s. The Atmega 328 function the same like Atmega 328p but the 328p has very low power consumption using the ATMEL’s PicoPower Features. Hence P stands for PicoPower.

What is 16bit timer?

The 16-bit Timer User Modules provides a down counter with programmable period and capture ability. The clock and enable signals can be selected from any system time base or external source.

What is a 16bit timer?

The 16-bit timer and event counter count up internal clocks or external pin signals with the 16-bit up-counter. If the value coincide with the timer register 0 or 1, the interrupt is issued. Periodic interrupt can be issued by timer match interrupt with the internal clock.

What is the internal architecture configuration of ATmega8 microcontroller?

Consider the block diagram representation of internal architecture configuration of ATmega8 microcontroller is: ATmega8 microcontroller consists of 1KB of SRAM, 8KB of flash memory and 512 bytes of EEPROM. In ATmega8 microcontroller all the registers are connected directly with Arithmetic Logic Unit (ALU).

How does ATmega8 work?

Using ATMega8 is similar to other ATMega microcontrollers, such as ATMega32 . Similarly, the micro-controller need to be programmed and added appropriate peripherals to get the output. Without programming the controller is an empty chip.

What is the SPI bus serial clock of ATmega8?

SCK (SPI Bus Serial Clock). This is the clock shared between this controller and other system for accurate data transfer. ATMEGA8 is a 28 pin AVR microcontroller. Although we have many similar microcontrollers, ATMEGA8 is popular because it is one of the cheapest microcontroller and provides many features in lesser pins.

What is Serial Peripheral Interface in ATmega8?

One of them is Serial Peripheral Interface. Four pins are assigned to Atmega8 to implement this scheme of communication. USART: One of the most powerful communication solutions is USART and ATmega8 supports both synchronous and asynchronous data transfer schemes.
