High Netters, I've been writting (*trying* to) a windows application which accepts data from an Analogic (FAST 14-1-4) 14 bit, 1Mhz ADC board which has 4Mb of local memory(not memory mapped to the PC). The board transfers data to the PC two words at a time via DMA (thats alot of DMA INTs!). The vender supplied software library is written for DOS (MSCv6.0), and not windows. I am currently using MSCv7.0, Windows 3.1, and running a 386/33 with 8Mb, and MS DOS 5.0. I'm new at this type of interfacing through Windows so..... Questions: 1) Do any of you have suggestions/comments on how to start this project? Any references, I've got the books by Petzold, Rector, Norton&Yao - these aren't much help for this. Is the book by Daniel Norton, "DEvice Drivers For Windows" something I should track down? I've got the library looking for some related DDJ articles from early this year. 2) Do I have all the software tools I need? I've come across an advertisment (pg 139) in this months DDJ (8/92) for TurboPower's Windows System Library. It apparently has, ammung other things, "DPMI access for advanced interrupt and memory control". Anyone heard of this product before? Maybe used it? Is this something I should consider? Comemnts and insights would really help me get started. Replys by email would be best (nus16@ttacs1.ttu.edu) I will be happy to post a summary if folks would like. Thanks for you feedback! ___________________________________________________________________ Michael Morelli Internet: nus16@ttacs1.ttu.edu Optical Systems Lab Phone: 806-742-3575 Texas Tech University
