Hi, I have a project in which I would need to get information from a certan Microprocessor http://www.emesystems.com/pdfs/parts/SX48BD.pdf [SX52BD/PQ] (the datasheet provides a similar model). And I have a FRAM memory RIC FM24C16-P datasheet FM24C16-P.
The main question is - Would I be able to download the program located on the memory and after that alter it. The program is written in assembler, but it doesn't really make much difference.
And if I would be able to download it, than how?
Thomas Tracy Allen is the designer of the OWL2 data logger and a generous poster on the Basic Stamps forums.
if you wanted code, he would either point you to the code , or give you pointers on how to write it.
if you were looking to interface with his stuff, he would probably be very helpful.
on the surface, it looks like you are asking to reverse engineer someone's products. typically once loaded the program is meaningless when you try to dump it out. in the basic idea, many of us think it is bad form. I surmise that by the number of people who looked, but did not comment, others get this impression as well.
it would be much easier to work on the front end, especially when the gentlemen who wrote the program is such a prolific contributor to others.
besides, with the resources available from the different sources on the net, you should be able to make pretty much anything that others are doing or have done. Weather station sketches are plentiful.
Hi, I have no idea what do you mean by Weather station sketches, but thanks for the information, I'll get on Parallax forums and ask the same question.
The project is for a welding machine for certain points on surface and reconfiguring it would take precious time. I am looking to simply download the program, manipulate it or rewrite, so I can upload it in other systems so I can replace the old system which is currently with the scenix microcontroller.
your first link
was to a page on the product site that is for a weather station / data logger.

going to the people who supplied the board and the program is the first place to start.
if they encrypted the program when they uploaded it, you may never be able to reverse engineer it. when creating a device for sales, encrypting is common to prevent anyone for doing a program dump and then modifying your program.
if you cannot find who wrote the program, you might be able to get/make an interface chip that modifies the signals of that chip to your needs.
alas exporting a program from a chip is not easy if at all possible.
if it were, there would be clones of all the nintendo games flooding the net.
