Practical Tips on Serial Communications
In many cases getting serial output from a computer or controller is a no-brainer. You don't need to know how it works--just hook up to a designated port or pin and there you are. But when you're building from scratch or troubleshooting a poorly documented system it can be valuable to understand some under-the-hood details. That's where this app note comes in.

Introduction to Serial Communication
Serial Communication, like any data transfer, requires coordination between the sender and receiver. For example, when to start the transmission and when to end it, when one particular bit or byte ends and another begins, when the receiver's capacity has been exceeded, and so on. A protocol defines the specific methods of coordinating transmission between a sender and receiver.
The scope of serial data transmission protocols is large and complex, encompassing everything from electrical connections to data encoding methods. This section summarizes the most important protocols and standards related to using the Serial Driver.

Mixing Java and C in Embedded Mixing Java and C in Embedded Systems
Java is a programming language and an environment originally conceived of as a platform for embed- ded software. But that was not how it gained its popularity. It was not until it became a way of adding functionality to Web pages on the Internet did Java get its start.

Introduction to RISC Assembly Language Programming
As the best way to gain an understanding of how a computer processor works at the lower levels, assembly language programming, is essential background for every computer science and electronic engineering student. It is, however, often considered an arcane and complex discipline because many first encounter it through the daunting instructions and registers of the Intel 8086 family.
Programming in a simple RISC architecture is very different due to the elegant and compact instruction set. Students of this text who have never programmed before and study it simultaneously with a course on a higher-level language report it is easier and more logical to program in assembly!

FreeBSD Assembly Language Programming
This tutorial will attempt to show you how you can use assembly language writing Unix programs, specifically under FreeBSD.
This tutorial does not explain the basics of assembly language. There are enough resources about that (for a complete online course in assembly language, see Randall Hyde’s Art of Assembly Language; or if you prefer a printed book, take a look at Jeff Duntemann’s Assembly Language Step-by-Step). However, once the tutorial is finished, any assembly language programmer will be able to write programs for FreeBSD quickly and efficiently

Serial Communication General Concepts
Serial is a very common protocol (not to be confused with Universal Serial Bus or USB) for device communication that comes standard on just about every PC. Most computers include two RS-232 based serial ports. Serial is also a common communication protocol that is used by many devices for instrumentation; numerous GPIB-compatible devices also come with an RS-232 port. Furthermore, serial communication can be used for data acquisition in conjunction with a remote sampling device.

Why are you Still Using C?
According to a poll on Embedded.com, 68% of the respondents are using C for developing their embedded software. Why do embedded developers choose C over C++? This article describes some of the key reasons to use the OO features of C++ in your embedded applications and how to evaluate the cost tradeoffs.

Program Organization for AVR microcontrollers
There are many ways to organize realtime programs. By organization, I mean the scheme you use to coordinate the interaction of concurrent program sections (e.g. interrupt service routines) , as well as the usual hierarchical structure of each individual program section. This document will show some of the ways or organizing your code for the AVR platform and try to address some of the tradeoffs of the various approaches.

The AVR Microcontroller and C Compiler Co-Design
High Level Languages (HLLs) are rapidly becoming the standard methodology for embedded microcontrollers due to improved time-to-market and simplified maintenance support. In order to ensure that the new ATMEL AVR family of microcontrollers was well suited as a target for C compiler, the external C compiler development was started before the AVR architecture and instruction set were completed.

AVR-Tutorial
The Single-Chip-processors of ATMEL are excellent for homebrewing every kind of processor-driven electronics. The only problem is that assembly has to be lerned in order to program these devices. After having done these first steps the assembly language provides very fast, lean and effective code, by which every task can be accomodated. These pages are for beginners and help in learning the first steps.

Interfacing the Serial / RS232 Port
The Serial Port is harder to interface than the Parallel Port. In most cases, any device you connect to the serial port will need the serial transmission converted back to parallel so that it can be used. This can be done using a UART. On the software side of things, there are many more registers that you have to attend to than on a Standard Parallel Port. (SPP)

8051 Tutorial: Serial Communication
One of the 8051’s many powerful features is it’s integrated UART, otherwise known as a serial port. The fact that the 8051 has an integrated serial port means that you may very easily read and write values to the serial port. If it were not for the integrated serial port, writing a byte to a serial line would be a rather tedious process requring turning on and off one of the I/O lines in rapid succession to properly "clock out" each individual bit, including start bits, stop bits, and parity bits.

Introduction to the MIPS Processor
This tutorial was written by Edsko De Vries and makes use of the Vivio animation of a DLX/MIPS processor.
The processor we will be considering in this tutorial is the MIPS processor. The MIPS processor, designed in 1984 by researchers at Stanford University, is a RISC (Reduced Instruction Set Computer) processor. Compared with their CISC (Complex Instruction Set Computer) counterparts (such as the Intel Pentium processors), RISC processors typically support fewer and much simpler instructions.

Beginners Introduction to the Assembly Language of ATMEL AVR Microprocessors
Assembler or other languages, that is the question.Why should I learn another language, if I already learned other programming anguages? The best argument: while you live in France you are able to get through by speaking english, but you will never feel at home then, and life remains complicated. You can get through with this, but it is rather inappropriate. If things need a hurry, you should use the country's language.
