• AVR watchdog reset timer-practical approach
  Practical approach to AVR microcontroller watchdog timer. How to program and control it.
  This is continuing of thread Why use watchdog variable timer. This post is about how watchdog timer on AVR microcontroller works and how to control it.As we mentioned earlier, watchdog timer is a distinct timer counter, which generates reset signal when it fill up.After watchdog timer counts up to maximum, it generates a short pulse [...]

• 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 [...]

• Build your own AVR JTAG ICE clone cable
  This is a post about how to build well known AVR JTAG ICE clone so called MiniICE that works with AVR Studio. AVR JTAG ICE can be used for debugging programs in real world and upload firmware to AVR as well.
  After unsuccessful attempts to run few programs who drive peripherals like USART and Timers on Atmega128 I decided to make JTAG debugger. I hope it will allow me to see what is really happening – is may atmega128 corrupted or something is really wrong with software or with hardware.The most widely used AVR JTAGICE clone [...]

• Control memory sections using AVR GCC
  If you programming AVR microcontrollers Compiler organises data in the way it looks optimal. But sometimes you are working with programs where you need you code parts to be located in specific program memory locations...
  If you programming AVR microcontrollers in C usually you don’t think how compiled program is stored in microcontrollers flash memory. Compiler organises data in the way it looks optimal. But sometimes you are working with programs where you need you code chunks located in specific program memory locations. For instance faced this problem while developing [...]

• Easy start with AVR EEPROM using WinAVR
  This is small guide how to start working with AVR internal EEPROM memory.
  AVR microcontrollers are loaded with some amount of EEPROM (Electronically Erasable Read-Only memory ) memory. This is handy feature allowing developers to store program parameters like service information, constants, menu strings etc. Atmel states that AVR EEPROM memory can be rewritten over 1000000 times. Reading is unlimited.In this article I am going to show how [...]

• Set up AVRStudio to use AVR-GCC compiler
  Short and ease tutorial how to work with AVR-GCC compiler in AVRStudio environment. Few steps how to start your first project.
  After release of AVRStudio4 there is possible to integrate AVR-GCC compiler in to it. As you know AVRstudio is a powerful tool which has assembler compiler- debugger, programmer, etc. Integration of AVR-GCC to it makes this tool much more powerful and more complete playground for developer. Plugin which is built in AVRStudio detects AVR-GCC [...]

• AVR ISP programmer using LPT port
  Simple AVR microcontroller ISP programmer that connects to PC LPT port. Works with PonyProg .
  AVRISP is very popular Parallel port programmer for flashing AVR type microcontrollers. Earlier I used programmer connected to com port, but frequently I needed this port for other purposes, I decided to make it work on parallel port. The programmer on parallel port is much simpler than connected to serial port, because there is no [...]

• Connect 6 LEDs using 3 microcontroller pins
  Using other microcontroller isn’t always a solution also as using decoder circuitry isn’t necessary as well. There is a simple hint on how to do this
  Sometimes you need more than you have. I am talking about microcontroller pins. Lets say, you have to connect 6 LED diodes but you have only 3 microcontroller pins available. To use other microcontroller isn’t always a solution using decoder circuitry isn’t necessary as well.There is a simple hint on how to do this:Connect diodes [...]

• Embedded C program libraries and linking
  Linker creates an output file from relocatable objects. Compiler is not one big program. It usually consist of up to a dozen smaller programs. These programs are controlled by some program so called “program driver”. This driver can be a makefile and make.exe program.
  What is compilation of program maybe it is more or less clear. But what is program linking? I am sure many beginners heard of this but done exactly know what it is. In a few words I can say, that linker creates an output file from relocatable objects.Compiler is not one big program. It usually [...]
