In this tutorial we are going to establish a serial communication between two ATMEGA8 microcontrollers. The communication established here is UART (Universal Asynchronous Receiver Transmitter) type. By this serial communication data can be shared between two microcontrollers, which is required in various embedded systems. Components Required Hardware: ATMEGA8 (2 pieces), power supply (5v), AVR-ISP PROGRAMMER, 100uF capacitor (connected across power supply), 1KΩ resistor (two pieces), LED, Button.

Software: Atmel studio 6.1, progisp or flash magic. Circuit Diagram & Explanation Let us understand the serial communication in AVR microcontrollers. Here ATMEGA sends data to the other ATMEGA in serial. It has other mode of communication but for easy communication we are choosing.

RS232 Data Logger - application which allows you to redirect communication data from serial port device into a text file. Adafruit Industries, Unique & fun DIY electronics and kits Adafruit Assembled Data Logging shield for Arduino ID: 1141 - Here's a handy Arduino shield: we've had a. Aging Morphs For Genesis Games.

The RS232 pin of first ATMEGA8 is connected to RXD pin of second ATMEGA8. More Opengl Game Programming Pdf. The data communication established is programmed to have: • Eight data bits • Two stop bits • No parity check bit • Baud rate of 2400 BPS(Bits Per Second) • Asynchronous communication (No clock share between two ATMEGA8) So we have two set registers for two ATMEGA8 differently, where one acts as TRANSMITTER and other acts as RECEIVER. Now for the RS232 interfacing between two ATmega microcontrollers, the following features must be satisfied for the TRANSMITTER and RECEIVER: 1.
