Introduction
Modbus communication interface for a multidrop network based on a master/client architecture.
It moniters and program devices to communicate between intelligent devices and sensors and instruments,to monitor the field devices using PCs and HMIs.
Modbus protocol defines a message structure,how pc address a ....etc

Abstract
This report describes the summer training experience in the Center
Institute of communication and computer research-KFUPM. I worked in
USAD 1 two students with a team of this project is to design the control unit
User command to send a four-wheels motorcycle and a control station installed
Robot warrior. In addition, we setup a wireless network to connect to the control
Control unit with requires software that station and we also design
Digital devices need to work properly. In this report I will describe all
Project work and w ....etc

AVR microcontroller based Solar tracking

This is a power generating method from sunlight. This method of power generation
is simple and is taken from natural resource. The aim of the project is to set the
solar panel for maximum power generation using the maximum sunlight available.
A stepper motor system is used for tracking maximum intensity of light. When there
is decrease in intensity of light, this system automatically changes its direction to
get maximum intensity of light.
Here we are using two ....etc

I am using UART for communicating 8 modules having LPC2148 microcontroller as a slave with another module having LPC2148 as master.But I am finding a constraint of wire length(I have read some articles on net which suggest a wire length of 2.6 mtrs for a baudrate of 56000bps) Can I replace this with MODBUS communication ?If yes where can I get information about modbus? ....etc
