What is an AVR ATmega8 microcontroller?

ATmega8 is a 28-pin, 8-bit AVR microcontroller, based on RISC architecture, designed by Microchip and is mainly used in the embedded systems and industrial automation projects.

What is an AVR kit?

AVR Development Kit with USB Programmer This kit is designed to prototype, test and build applications/projects on 28 pin and 40 pin AVR Microcontrollers like atmega8, atmega168, atmega328 etc and 40 pin AVR devices like atmega16, atmega32 etc. The Kit comes with a USB Programmer and host of interfaces!

How do I program my ATmega8 microcontroller?

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.

What are AVR based boards?

AVR is a single chip AVR development board which was developed by Atmel Corporation in 1996. It architecture was developed by Alf-Egil Bogen and Vegard Wollan. AVR obtain its name from Initial alphabet of each developer and was named as advanced virtual RISC microcontroller.

How many timers are there in ATmega8?

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

How many ports are there in ATmega8?

Atmega8 AVR Microcontroller Architecture I/O Ports: It has three ports, namely port-B, port-C, and port-D and 23 I/O line can be attained from these ports.

What is 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.

Why AVR microcontroller is used?

It contain on chip central processing unit (CPU), Read only memory (ROM), Random access memory (RAM), input/output unit, interrupts controller etc. Therefore a microcontroller is used for high speed signal processing operation inside an embedded system.

How do you program an AVR microcontroller?

Connect the AVR MCU to a programming tool. Open Atmel Studio and navigate to Tools->Device Programming dialog box. Select the programming tool, device and the programming interface. Read the Device ID to verify the connections between the tool and the device.

What is 16bit timer?

The 16-bit timer and event counter count up internal clocks or external pin signals with the 16-bit up-counter. Periodic interrupt can be issued by timer match interrupt with the internal clock. Value of the 16-bit up-counter is fetched into the capture register according to the signal change of the external pins.

How high can an 8-bit timer count?

255
8-bit Timers can only count up to 255. Be sure to select a prescalar such that your OCR value will fit in 8-bits.

What are the main features of the ATmega8 microcontroller?
