Use the AVR then. There are good C compilers for the HC08, but some of the
things you need to do to make C work on that platform aren't efficient ;)

For the '08, Bytecraft is the only place I know of to get a C compiler.

At no cost, you can try out the permanent Special version of Metrowerks
CodeWarrior for the entire HC(S)08 series. In addition, you can evaluate the
full version for 30 days. There are some evaluation boards available at low
cost ($50 to $300, depending upon the chip - I think).
You can either download the entire software (over 700 MB installed) or you
can request a free CD, or both. If you get the CD, also get the free CDs for
the other Motorola chip series available, since the shipping costs would be
the same if there are more than one. The URL for the HC08 is:
http://www.metrowerks.com/MW/Develop/Embedded/HC08/Default.htm
CodeWarrior is fairly simple to use, especially if you follow the tutorials
or the example projects included with the installation.

You *can* program the '08 in C, there are no major warts in the
architecture that make it compiler *un*friendly, but the lack of
general-purpose registers means that compilers tend to use
pseudo-registers on the zero page and subroutines to manipulate them.
Cosmic do a pretty good '08 compiler, given the core's limitations.
The AVR is much more C-friendly, being essentially a "narrow" version of
standard RISC processors.

Well for the ATMega at least gcc is available, which I have used quite
succesfully on the AVR series, including the ATMega32. There are quite
a lot of community support for the AVR using the gcc tools.
As for the 68HC908, I cannot comment as I have not used this family
before.

Hi Folk
After a quick scan to look for a MCU for a particular task, I have two
specific MCUs in mind, they are:
Atmel ATMega32L and Motorola MC68HC908AP32.
Between the two, is there anyone out there who has experience in
those? Which one is better in terms of debugging, and development
environment and support? Also, speedwise, which is more code
efficient? Any compiler to recommend?
Of course, I am developing in high level C environment.
Thanks in advance for any help.
