Whats the best AVR toolchain

[jube]

hi a bit new to the AVR line, was wandering whats the best/ most industry standard AVR compiler/IDE ( c/c++ ) to hunt down? Save me downloading them all and comparing which had to do with ARM and PIC

Hi.


I have used ICC, Codevision and IAR.
I like 3 all of them for the different things they offer ...

ICC and Codevision:

Likes : Both have a code generator to help you setup your peripherals and interupt service routines real quick.
Personally I feel ICC has a better code generator. But codevision seems to give me a more compact code so far. Probably it's my settings which I miss. Nevertheless, both compilers worked great in all my projects. 

Dislikes : Although both compilers can do ISP programming directly but not debugging. You need to debug your code thru AVRStudio.


IAR :

Likes : is a bigger package and you can write in C++ too. Lots of options and industrial standards checks like Misra conformance. With it's CSPY debugger, it integrates to JTAGICE, Dragon and AVRISP readily without having to launch the AVR Studio. It also has profilers, code coverage tools and also Kernel Aware monitors for UCOS RTOS.... Very nice features

Dislikes : Could not think of any now.... other than having to understand the tool chain takes a while. And ... there is no code generator for peripheral initialization.

Codevision makes no good code. I not test IAR, but test many other's. WinAVR-GCC is free С compiler(as a plugin uses in AVRStudio) has disadvatage:"You need to debug your code thru AVRStudio." As IDE->eclipse, CODE::BLOCKS, KAMAVR(stopped in develop).
AtmanAVR-chinese IDE based on WinAVR-GCC has debugger like AVRStudio. 100$ or trial 30 days. Crossworks by rowley has debugger, but i don't understood-it can make ELF/COFF to use with Proteus or not ? VMLab-like small Proteus. V3.14 is free. Include oscill,keyboard and many others. Interface with WinAVR-GCC, CodeVision. I use it with GCC&assembler. May be some else exists ? I see TKStudio-chinese product, but i don't understend hieroglyphic.

i understand the GCC toolchain well since use the MIPPS version in psp programming, as far as i understand GCC does not support avr as a naitive target, or am i wrong ? i assume WinAVR is a GCC patch ?
Anyway am assuming a comercial compiler will be better???

I recommend IAR and CodeVision.
 
CodeVision:   It's easier to use and a lot of examples and configuration wizard for beginner. For large project, IAR should be the right choice, I think.

Anyway: AVR architecture is the best over other 8-bit microcontrollers, because of unique technology such as
1. Number of system clock cycle : 1
2. Wide operation voltage range without using built-in regulator: (1.8 - 5) V
3. Easy flash programming via LPT port
and so on.....

Happy Microcontroller Pprogramming

AVR architecture is AVR architecture. IAR want money for product. GCC is free. AVRStudio is free too. GCC is plugin for AVRStudio. Need the choice. Or search the crack, or use freeware. Or interlive.

Hai Everybody,

As far as my recent experience concerned, please beware about the results produced by AVR Studio in regard to timer simulation. Its gives frustrated results for me but in practise i got the result what i expected. Be cautious in your endeavours friends.
