My bad, I realize it is Hex not Binary. The problem I have is that when I click on your link to download the test_leds.hex file it opens up as a web page. It is not downloading as a file that I can save in some project directory.
I can copy and paste to a text editor and save it as a .hex file, but I get an error message from the programmer if I try to use it in that format. If there is something else I need to do with the web page that opens up when I link to this file, it should be explained in the tutorial.
I did successfully load a hex file to the attiny2313 but I had to find another tutorial blinktheled.c file which I compiled and successfully loaded the hex file on the chip.
This has been a great and very detailed tutorial, up to this point, but it just fell short at this simple link. Now that I can communicate with the uP I'm off to learn to write code for AVR's.
