AN INTRODUCTION INTENDED FOR PEOPLE WITH NO PRIOR AVR KNOWLEDGE - AVRFREAKS.NET

2. This is the name of the project. It could be anything, but "Leds" is quite

descriptive of what this program is going to do

3. Here you can specify if AVR Studio should automatically create a initial

assembly file. We want to do this. The filename could be anything, but use

"Leds" to be compatible with this tutorial!

4. Select the path where you want your files stored

5. Verify everything once more, and make sure both check-boxes are

checked. When you are satisfied, press the "Next >>" button

Step 3: Selecting Debug Platform

The AVR Studio 4 Software can be used as a frontend software for a wide range

of debugging tools.

1. AVR Studio 4 supports a wide range of emulation and debugging tools.

Since we have not purchased any of these yet, we will use the built in

simulator functionality.

2. ..and we want to develop for the AT90S8515 device

3. Verify all settings once more, then press "Finish" to create project and

go to the assembly file

Step 4: Writing your very first line of code

AVR Studio will start and open an empty file named Leds.asm. We will take a

closer look at the AVR Studio GUI in the next lesson. For now note that the

Leds.asm is not listed in the "Assembler" folder in the left column. This is because

the file is not saved yet. Write in this line: "; My Very First AVR Project" as shown

in the figure below. The semicolon ; indicates that the rest of the line should be

treated as a comment by the assembler.
