The USBasp AVR programmer arrived today so I lost no time connecting it up to give it a try. This is a clever little beast that uses a software USB stack on a pre-programmed ATMEGA8 processor. It works directly with AVRdude to program your target processor with the minimum of fuss.

AVRMacPack works well enough in Xcode but I don’t understand Xcode so I wen looking for an alternative. While trawling through back issues of SERVO magazine, I came across a pair of articles by Dennis Clarke about setting up Eclipse with AVRMacPack and the avr-eclipse plugin. One of my recurring mistakes is the feeling that you can’t have enough development tools so I gave it a go…
The AVRmacpack for AVR development on the Apple Mac contains command line tools. These are all well and good if you want to do things the traditional way with text editors, terminal windows and make files. No real problem. However, if you want the benefits of a modern IDE with things like function lists and refactoring, you might want to try Xcode. It is, after all, supplied with your Mac.

As a first step, the blinking of an LED is an essential part of development for a new processor and environment. I had read somewhere that the bootloader on an arduino was compatible with an avrisp/STK500 programmer. That turns out to be quite right!
After many hours playing with the new iMac, it is time to get something ‘proper’ done with it. By proper, I mean, of course, some microcontroller development. To start with, I have been looking at the AVR.
