[time-nuts] A Open Source GPIB project

[Hui Zhang]

Hello Bob:
    
    To generate program file, you need the KEIL develop environment, or you can just using HEX file to program MCU directly, the HEX file will put on the GIT website late time when all software function finished. If anyone  interested in HEX file of current version (not including off-line acqurie and Talk Only function), send off-line email to me, I will send you a copy.


    The other url of original email contain the schematic and PCB files, you need Protel DXP files to open it, the PDF format schematic file and a guide document will be published late, maybe few weeks. The document will be Chinese language, but If people need, I think I can translate a short English version (if you guys don't hate my bad English). And I will collect some questions and forward them to developers. But you know, it's a Open Source project, all developer uses their spare time to do these job, so the question maybe can't be reply quickly or 100% responsed. Anyway, this project is still in progress, if any important news happened, I will let you people know.


Best regards.

>> Here is a open source GPIB project that developed by some Chinese amateurs, the developer released all of the information about hardware and software, including circuit diagram, PCB diagram, firmware source code, communication protocol and upper computer PC program (late on). The project name is CARE.If you are interested you can build your own CARE, but please don’t use this open source project for commercial purpose.
