Setting Fuses As mentioned before, fuses are used to set a couple of things that might need to be set before the actual software starts to run. As a beginner you should not tinker with most of those settings, because it is possible to lock yourself out of in-system programming. The most dangerous fuse bits in that respect are SPIEN (SPI enable) for obvious reasons and RSTDISBL (reset

Installing the Software As mentioned, there are many options when it comes to software. One standard program, which is available for many operating systems is avrdude. Unfortunately, it is a command line tool, which makes it less than ideal for beginners. But there are GUI frontends available. I decided to use AVRDUDESS for this tutorial. And it is quite easy to use. But first,

What Hardware do I need? Obviously you need the controller. This can be any Atmel ATtiny or ATMega. You need a circuit board to put the controller in (the "target board") and you need an ISP programmer. Since ISP uses a serial format, the programmer can be rather compact. There is a wide variety of programmers on the market, from full featured expensive to cheap and simple. Since

Introduction Many of my projects use AVR controllers from Atmel. And they need to be "programmed". This means that the software needs to get written into their internal program memory. For beginners, this can be a major stumbling block in any project. And I do get lots of questions in connection with programming. So I decided to write this tutorial. But my intention is not just to

Several people asked me how you connect an ISP programmer to an ATMega8. It never occured to me that this could be a problem for anyone. But anyway, here is a schematic. Over time, I will write a tutorial on how to program AVR controllers. Please note that the header shows Atmel's standard pinout for the 10-pin ISP header. Most programmers use that same pinout. But to be safe you should check
