Hi

I come from the Atmel AVR camp (please don't throw rocks at me!), but have decided that I want to see the world I'm currently playing with the Dallas 8051-based uCs and am just starting to look at HC08. I work in ANSI C, when in embedded mode. I have been very impressed with avr-gcc and avr-glibc; a bit more so that with Atmel themselves...

Does anyone know of an Open Source toolchain for this processor core? I believe that SDCC is supposed to support HC08 some time in the future, but can't get a definitive answer from the development list as to the current status of this support.

I've had a play with the evaluation CodeWarrior, but 1) I don't want to have to boot a machine into Windows everytime I want to use it, especially since only my old laptop has a Windows partition and 2) I find it a bit over-done for my taste; twenty years behind the command line, man and boy - graphical development environments just don't feel quite right. 3) I try to avoid closed-source software when possible.

Cheers

Welcome, for the HC08 or the newer HCS08, there aren't any open source compilers I am aware of, you are stuck with either CW (16K free)or the Cosmic compiler which has a free 4k version.

However GCC does exist for the S12 (http://m68hc11.serveftp.org/), so if it open source is a must then you could try a device like the S12Cxx (32K to 128K falsh family) to get started with.

Anyone got this working under Wine?

If I can't get a programme to fit into 16k, I'll be letting down my fellow generation of Sinclair users (And that was using BASIC!)

Ah, that's more like it! gcc gets my vote any day.

There is indeed an Open Source port of SDCC for the HC08 MCU!

You can find it here:

http://sdcc-m08.sourceforge.net/

I have not tried it yet, but will post my results here when i have.
