AVR DDS signal generator V1.0 Sometimes we need simple signal generator with various waveform and frequencies. You can by a professional with variable gain and many additional functions. But you might want to build one. This small project is dedicated for building simple AVR controlled DDS signal generator. Sometimes when tuning various electronic hardware we need simple signal generator with various waveform and frequency. One of the options is to by a professional with variable gain professional coating and many additional functions. But if you are an amateur you might want to build one.

AVR-GCC ABC Step by step tutorial how to start working with AVR-GCC compiler and one open source toolset WinAVR. Thread consists of two posts: http://www.scienceprog.com/avr-gcc-abc-1/ http://www.scienceprog.com/avr-gcc-abc-2/ This time I decided to lay down some information on using AVR-GCC compiler. I am not going to rewrite what’s in documentation is already written, but just write down some issues, what can help you start using this amazing tool.IntroductionProbably the most AVR programmers had a question in their mind what compiler to use for [...] avr-microcontrollers in Public bookmarkswith avravr-gccccompilerkickprojectstartwinavr
How to use inline ASM using WinAVR The article about how to embed the asm code into C program using WinAVR (AVR-GCC compiler). I have been working on optimisation of one of my C codes. I needed one function to be as optimal as possible. I decided to use inline ASM to achieve this. I decided to write few lines about this.There are few rules that is necessary to follow. Each ASM statement is divided by colons into [...] avr-microcontrollersuncategorized in Public bookmarkswith asmassemblerccodeembedinlinetowinavr
Interfacing PC keyboard to AVR microcontroller In many situations you need some kind of human interface to your microcontroller project. In this example is interfacing AVR microcontroller to standard PC AT keyboard described. Properties:Interface AVR to standard PC AT keyboard;Only two I/O lines used. One line is also connected to external interrupt pin of AVR;No external components is needed for interface;Included C source reads from keyboard interface and converts to serialIn many situations you need some kind of human interface to your microcontroller project. In this example is [...] avr-microcontrollers in Public bookmarkswith atmelavrcinterfacingkeyboardproject
