I am trying to decide what software development environment to use to develop real-time applications for a Motorola MC9S12Axx microprocessor. Software subsystems I will develop to run on the uproc include: - multidrop, interrupt driven, serial communication with error detection and recovery - interrupt driven A/D sampling and FFT analysis - I2C and 1-Wire widget communication - misc simple control algorithms Selection criteria for development system include: - cost - learning curve - setup and maintenance - environment : Windows or Linux - vendor/user group support - compatible with experience of Wash. U. students My background and biases are: - very strong in C and C++ - strong in Microsoft Visual Studio C, C++ and Visual Basic environments - proficient in Java - strong (but not current) in assembly languages but not w/ Motorola chips. I hope to avoid assembly language as much as possible. I have played with Metrowerks CodeWarrior. I find this to be a sophisticated/complicated development environment and probably more than I really need. The learning curve looks like it would be formidable and since I don't see a steady volume of work in the future centered around uProc development I am concerned that the overhead of relearning what I need to know could present a major support problem. I also have significant problems with PE beans. My interpretation of what I see is that an instantiation for a bean is for a specific device which leads to multiple copies of routines with hardcoded device ID's. For example if you want to use the AsyncSerial routines on two SCI ports you get two copies of all the code - one for SCI0 and one for SCI1. Do you have any thoughts/suggestions for me? I have looked briefly at Imagecraft and Cosmic but don't really know anything about them. Are there any reasonable development environments that are free running on Linux? Thanks in advance for your help. Tim C. Perry DSA, Inc. 314-576-9794 |

Recommendation on HCS12 IDE platform

Perhaps you might want to look at the GCC compiler for the HC11/HC12. Newsgroup: . In terms of a solid tool, I recommend Cosmic. There does not seem to be as much discussion on this list re/ Cosmic as there is for CodeWarrior, but I wonder if that is simply because it is easier to use (command line, no beans and stationary, etc.). BTW, Cosmic's front page mentions "...development tool sponsorship for University projects ..." (http://www.cosmic-us.com/). 607-656-2597 -----Original Message----- From: Tim C.

Try the GNU tools ($0.00). The only downside is the compiler will not use the entire 9S12 instruction set (only the HC12 subset) - which should not be a problem for you. Both linux and windows versions are available. There is an active Yahoo newsgroup for support: http://groups.yahoo.com/group/gnu-m68hc11 Start at http://www.gnu.org/software/m68hc11/ and http://stephane.carrez.free.fr/m68hc11_port.html There are also several linux IDEs available, varying from OK to excellent. -z --- In , "Tim C.

>How do you go about debugging? >Have you succeeded in interfacing a debug pod to GDB? I haven't done any debugging with BDM or GDB. I might look into it someday, but for now there's no special debugging support in EmbeddedGNU. I just use the terminal window to do some simple debugging. I want to build up more hardware profiles and add more configuration features next. If anyone would like to contribute demo programs or hardware profiles for specific boards (6811 and 6812 flavors), please do so! I'll mention your name in the files you contribute.
