This project is to update the operating code for an electronic stimulator device designed in the mid 1990s for a small company seeking to update the equipment. Project is to analyze source operating code and to clean it up, update it and salvage as much as possible for use in new microcontroller. Write new code for updates as needed. To be effective at this job you will need good experience in the following: * Be an embedded program system engineer used to working with hardware and firmware interfaces * Familiar with C * Familiar with assembler language also used in this code for lower level functions * Familar with the old Zylog Z-80 processor which is what was used with this code Because there is extensive work into creating this code and most of it is in C+ we hope and expect that most of the code for LCD interface screens and functionality can be salvaged so it does not have to be re-written from scratch for the new processor. We have not selected the new processor yet, but are considering a newer Zylog processor with more memory and capabilities. Once the code is analyzed we would welcome a suggestion for this. If you believe you have the qualifications and availability for this project, please send information about your experience along these lines. There will be several phases to this project: 1) Discovery phase - analyzing the old code to estimate time requirement for job 2) Cleaning up code for use in new processor 3) Writing new code as needed to work with new processor 4) Installing in new processor, testing and debugging To receive the code to analyze contractor selected will need to sign a NDA.

Hello.. I was programming z80 assembly early 90s, and got two yamaha computers that runs on it. I am programming C and C++ for more than 12 years for well known names. I can send you my CV in a private message. I love C and it is my main development language. I used it for several architectures and processors high level and low level systems programming. I am a good fit for your requirements; yet will never be the best financially. But by working with me you will know how to finish things an optimum time and cost. I also have experience developing touch LCD drivers for embedded devices. I have no problem to go on an NDA with you. Send me back to send you my CV in a PM. I love C, so lets go to build big things together. Best Regards Mahammad

I am an experienced embedded systems engineer, familiar with both the software and hardware sides of the equation. I have experience with a Z80 derivative (Rabbit), as well as a host of other microcontrollers and processors. My experience designing a large number of embedded systems from the ground up, as well as modifying previously existing systems, will enable me to quickly determine the path that is needed to complete your project. My profile has some examples of projects I have completed. I will try to post more information in the PM. Thank you Steve Jarpe Jarpe Data Solutions, Inc.

Hi, We have extensive experience with embedded software projects. I fully understand that you won't divulge your source code openly, so I suppose that you expect a bid for the analysis only. This bid covers : - Analyze the current code - Determine what needs to be rewritten and what can be salvaged from the current code base - Determine the magnitude of the migration toward a new microcontroller The deliverable would be a report stating the results of the analysis described above. I hope that our bid satisfies your expectations. Sincerly, Alexis

I've been doing embedded systems since the 80's. I still have all my old Z-80 manuals. Sounds like a simple port to the new CPU. C and assembly coding are a given on this type of project.

I'm an electronics Engineer, familiar with Embedded hardware and software. I've dealt with different families of microcontrollers including 8051, 68HC11, microchip pic and dspic etc. I've programmed all these controllers in assembler and in c language. I also design whole system, including printed circuit boards. I think I'm the right guy for your job and I'm available. Please contact me and we can have further discussion about your project.

I offer over 30 years electronic design experience, hardware, firmware, special applications software. In the 1990's I did reverse engineering (redesign for form, fit and functional equal with newer state of the art components) for US Air Force contracts. (I am in US, Texas.) More recently, since 2000, I have done developement of commercial products having embedded microcontrollers. Code development was with ANSI C environment tools. Your product has an embedded device with a Z80 core, a Zilog incarnation of the 8080, so instruction set compatable. Naturally C (ANSI compliant) will always compile in any other development environment. Only hard coded memroy mapped hardware would need to be updated. Assembly will necessarily have to be rewritten. Also do note this applies whether the processor core is 8080 instruction set compliant or not as any newer Intel instruction set device will still have different memory mapping. Practically for such an old design a black box approach, create a form, fit, and functional equivalent with respect to existing I/O I believe is the best. For now my bid is a very rough estimate. I must see much more detail to reach a final bid.
