I want create DD file for my project. I have evb with msp430 and dallas DS8500 hart modem. I implement some command for device. I will connect device with sw Pactware through Microlink hart modem. I have wrote simple file in DD language and I find this presentation (http://lamspeople.epfl.ch/kirrmann/Slides/AI_411_HART.ppt) with any DDL compiler. How can I compile the DD file?
