I know there are a few AVR enthusiasts here on CP but didn't know if anyone used assembler. I don't use it very ofter as I'm trying to push C++ now that the Atmel Studio supports it but it is handy to know and the more you know about the hardware the better.

C++ is a hard push on any embedded system, most are still stuck in C. I tried to convince an old developer to use C++ on an ARM once, he nearly had me crucified.
It's hard to get people to change I've been in a couple of positions where I've pushed C++ even to the point of writing a framework, giving classes and such but they were set in there ways and I finally just did my own thing and left them to there's. I'm using the ATMega1280 and ATMega2560 boards for my C++ projects and the have 128K and 256K flash memory respectively so there's no "limited memory" excuse and since C++ runs just about as fast as C that shouldn't be a problem. The IDE has finally started to support it and I've been writing a lot of libraries in C++.

I for one would be most interested in an article of that nature. With the 328p having such limited program/memory space, I'd love to see such an article.
I have done a couple of project using the 328P and C++ and it works very well.

Indeed. I've done a couple too. But as with desktops, sometimes a c/c++ just doesn't seem to cut the mustard. (using avr-gcc here) One cant be sure that a register value wont be chucked away or that a register wont be loaded twice. Specifically, I'm playing with (a) a musical instrument synthesizer with waveform display and am looking to add the ability to add tracking info - i.e Make an (amiga) .mod player. (b) a cheap and nasty DSO/bus sniffer (c) a 6, 7 or 8 channel RX compatible with the protocols used by both the Turnigy 9x and Husban transmitters. Every byte left is well appreciated, sine they each use a channel-hopping protocol and have rather short frame-times. I need a couple of largish static buffers and few wasted cyles. To maintain a lock and avoid dropping packets, one needs to be rather efficient with the 328. I'm able to successfully change channel between each packet, but still cant capture more than about 5 or 6 packets in a row before I drop one. Interference isn't the problem, it's just a matter of timing. So memory for the channel hopping tables and speed to avoid packet loss are my main interests. This also means that an a7105 2.4ghz module driven by the 328 doesn't satisfy the binding requirements of either a commercial Turnigy/Hobby-King RX.

It certainly will be. I am learning AVR Assembler as a part of my Apprenticeship, using the STK 600 Board[^]. We are currently implementing a Real Time Clock, being triggered by the interrupt signal. Maybe I am going to put it up here when it is finished.

As you say nothing ventured nothing gained. I'm working on converting it now and should be ready in a couple of hours.

Should be similar. Published it about 1-2 hours ago! AVR Assembler 101[^]

Well, anything Low Level get my vote :)
Thanks Glenn, I submitted it yesterday and it's getting a fairly good reception so I guess a lot of people think like us. :)

Most of the Arduino boards use a processor with 32kB flash ('328, or '32), and all use C++ for 'wiring' code http://arduino.cc/en/Products.Compare[^]
A lot of hobbyists use the Arduino IDE which has a lot of C++ code and I don't use it so haven't delved to deep in it. But most people that use it seriously use Asm or C for production!

I'm working on AVR so wouldn't mind you posting on it. But whether anyone else would be interested on CP I don't know.
"Program testing can be used to show the presence of bugs, but never to show their absence." << please vote!! >>
Submitted it yesterday AVR Assembler 101[^] Didn't realize so many people on CP were interrested or worked on AVR.
