ATMEL DRAGON SIMULATOR
Built-in simulator for more possibilities More so, you can begin your work by selecting one of the numerous pre-existing samples.
ATMEL DRAGON CODE
Part of the package, the editor facilitates code writing by adding suggestions as soon as some letters of a certain symbol are put down on the canvas. Projects can be built from the ground up, tested and verified within the same environment.
ATMEL DRAGON SOFTWARE
Design, test and build your software projectsĮspecially created to provide a means of putting together applications based on Atmel ARM Cortex-M and Atmel AVR microcontroller- technologies, this program comes fully equipped for a wide range of tasks. When it comes to special devices and components, you can use dedicated tools like Atmel Studio. If you are a Windows user, I recommend that you download MSYS, a collection of GNU utilities which will give you many of the nice Unixy command line utilities like sh, gmake, grep, etc.Building applications for specific platforms and checking them for errors before acknowledging they are suitable for production are tasks that many developers have to deal with on a regular basis. The above notes are for OS X, which translates easily for Linux and variants.
Some useful resources for AVR Programming But these chips are amazing and can do a lot - so experiment, and have fun! :-) This is a vast topic, and if you want to go beyond blinking an LED, some research and tinkering is unavoidable. I know this is short, but it should get you started. Now you can remove the programmer, and by supplying 3V to VCC and GND pins, it will still work (as it should!). You'll get a flurry of messages from AVRDude, and then if it all works, you will see a happy blinking LED.
This is how you program the chip from the command line: Here is a Makefile I modified from the one generated by CrossPack. Next, you need a Makefile to do the magic of building your code. The program below toggles PB3 on the chip on and off, making the LED blink. This will help you compile your code, generate the hex file, and flash it into the chip. There are many ways of doing this, but I use AVRDude. Next, you need some tools to program the chip. Hook up a 100 Ohm resistor and an LED to PB3 (pin 2) of the ATtiny85. One thing to note is that you are powering the chip using VCC from the programmer - so make sure that you enable that power switch on the programmer, if yours has one.
ATMEL DRAGON INSTALL
(Follow the instructions that came with the programmer to install drivers, etc.). The programmer connects to your computer via the USB port. These are clearly marked on the programmer, and from the above diagram, you know the corresponding pin on the chip. The connections you need for programming are VCC, GND, MISO, MOSI, SCK and RESET.
Now, we need to hook up our programmer to this chip. Here is the pin information for the ATtiny85, from the datasheet. But don't worry, over time it will start to make sense. If this is the first time you are looking at one of these, it will look horribly complex. Next, you need to get the ATtiny85 datasheet from Atmel (Time to do a web search!).
Look for USBtiny programmers - in India you can get one of these for about Rs. But you can buy much cheaper programmers. I am using a Pocket AVR Programmer from Sparkfun. The first thing you need to program the chip is an AVR programmer. So here are some quick notes on getting started with the ATtiny85. I have articles here on ATtiny84, but not on this chip. I just got the batch of ATtiny85s I ordered for some pals at a local Maker group. Getting started with ATtiny85 (AVR Programming)
