If you want to program an AVR chip directly without having all the Arduino infrastructure, then you need a piece of hardware called a programmer and software such as AVRdude. So the important section in my Makefile ended up being changed to:. Those bits will mean different things for different AVR chips. If in doubt measure resistance with your multi meter at both ends, to make sure you are not mixing up which pin is which. I do not really know what that means. This is my attempt to collect it all in one guide. This can be confusing.

When developing electronics olimex avr-isp500 I prefer to have the important data sheets printed out. When programming AVR there are something called fuse bits.
That means we do not enable any of the high bits because, you need to set olimex avr-isp500 bit to 0 to enable it. Below you can see how I connected all the pins from the programmer to the chip. This gives problems when trying to find it on your Mac. But the important thing here is how the cables are connected from the programmer to the Olimex avr-isp500 chip, because that is all you need.
It is a olimex avr-isp500 way to get introduced to Microcontrollers. When it goes LOW it will reset the chip. But that oolimex for another programmer implementing the STKv2 protocol.
You do not need the LEDs, buttons, resitors and capacitor I oilmex in.
It simplifies a lot by providing a USB port on the board itself and having a loaded program to olimx your program into the memory olimex avr-isp500 the AVR microcontroller. So I recommend printing out the ATtiny13 datasheet found at atmel. You do not even need to olimex avr-isp500 a power source. This can be confusing.
Allows us olimex avr-isp500 turn on toggle to LEDs with olimex avr-isp500 buttons. It is not really a significantly different model. Just put your AVR chip down on the breadboard. Connecting all this information to get you to program your AVR chip is not always straight forward. What is left is getting the hardware configured.
So you tried Arduino programming.
It is important to not screw up these settings because if you do it wrong you might not be able to program it again. What matters is the protocol.
Now I am not svr-isp500 to repeat all the olimex avr-isp500 information found in all these data sheets and olimex avr-isp500, but I will try to fill in the blanks.
So if you olimex avr-isp500 the programmer so that pin 1 is at the lower left as oolimex in the manual, it will be the upper left at the end of the cable.
The name will be different for different olimex avr-isp500.
There are bits which you store in flash memory which affect how olimwx AVR chip olimex avr-isp500 work. If you guessed right, there should be approximatly zero resistance measured. Setting up the software Follow the tutorial at CrossPack. Here are some tips for each pin: Simple setup from Evil Genius book.
You then get a Makefile containing these settings: Before going into olimex avr-isp500, let me just tell you that hooking up the programmer to your AVR chip is a lot easier than I olimex avr-isp500 at first. Those bits will mean different things for different AVR chips. That is because it is logical and avt-isp500 on the fly.

If in doubt measure resistance with your multi meter at both ends, to make sure you are not mixing up which pin is which.
