AVR-Chat

I do that all the time: high speed encoders, or special low-latency
interrupt handlers in assembly (pure) using GAS (Gnu Assembler).  Read the
WinAvr GCC FAQ and look at the GAS manual.

The only restrictions, at the moment, is that if you want to do symbolic
debugging with the simulator you need to use .coff format and to get that to
work requires some magic in your assembly source.  Hopefully the next
release will have dwarf-2 debugging enabled in the assembler and the need
for magic will go away (hope, hope...)

| Subject: [AVR-Chat] GCC-Avg and pure assembly
| 
| Hi all,
| 
|   I've written code using the gcc-avr compiler in C for various projects,
| but I have some code written for Tiny13 and Tiny11 chips that are
| straight assembly. Has anyone written pure assembly using gcc-avr?  Can
| we use just the assembler
| to write code simply in the gcc-avr framework that can be downloaded to an
| STK500 programmer board?  I've not checked to see if AVR-dude can handle
| the "no ram" chips as well as the bigger chips...
| 
| thanks,
| DLC
