Any suggestions?I'm using linux as a development platform for Freescale Coldfire 52235, but the same gnu toolchain is available for Windows (even though I've never used it): http://www.codesourcery.com/gnu_toolchains/coldfire/download.html Petter -- A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing on usenet and in e-mail?
Any uC manufacturers have free c compilers?

You can download a demo which is fully functional for 45 days and then becomes code limited, but will still be perfectly adequate for most hobby projects. http://www.imagecraft.com/ -- John B

Nothing fancy but it gets the job done. I've developed with it for Infineon C515C and Atmel AT89C51CC03 (both varieties use 8051-style cores).

They have suport for ARM, AVR, MSP430, and MaxQ: http://www.rowley.co.uk/ -- Grant

Any suggestions?Zilog has a free unlimited C compiler, available in their ZDS2 toolchain: http://www.zilog.com/software/zds2.asp It runs on Windows, fully supports their dev boards, and those boards cost very little. You should check them out, as they seem to fit your bill perfectly. Regards, D.

The last toughest > requirement is I use windows, so no linux. Any suggestions?It is probably better to ask who does not :) Most small parts have free compilers. Zilog are free across the whole range, Freescale are free up to a ceiling. Both these companies own Compiler companies. Atmel AVR8, AVR32 and C51 all also have free c compilers. You should also test the ICE pathways, that may matter more than the compilers. Easiest access to ICE in the C51 series is via SiLabs, who also have very good analog performance, and low power (and that can matter more than 'which core') Atmel have AVR studio Debug tools, but their ICE pathways are at the more expensive end of the scale. -jg

As these guys are the maintainers for these gcc ports, you get the most cutting edge versions and their support people are extremely knowledgeable because they work on gcc. The same applies to Red Hat, although they work on different aspects of gcc. I can also recommend ImageCraft as a source of cheap, easy to use, and well-supported compilers for a number of targets.

In fact, I spotted a zilog part that might fit the bill perfectly. I want to do some 12V Batt charging/management for the boat and 4wd and I figure that I can roll it all into a single package. Might have a poke around the Atmel site and see what parts they have. Its a shame the Microchip stuff is so dear. I have an ICD2 as well lying around somewhere but I just cant justify spending US500 on the c compiler. Thanks everyone.

Size limits are more than adequate for smaller parts (4K on AVR, 32K on ARM IIRC) Hi-Tech do a free version of theor compiler for the lower-end PICs. And there is GCC for a number of devices.
