Is this possible? I would like to access a Bit3 PCI to VMEBus adapter, download some data from memory from the VMEBus backplane, and plot this data. This is running under NT4.0 or Win95/98. I intend to use Allegro to do a simple x-y plot with a spiffy grid in contrasting colors. The Allegro portion is pretty simple and plenty fast enough. This is time or frequency domain data from a DSP board. The Bit3 can be accessed from Windows using a DLL or by linking in the appropriate libraries. Unfortunatly, the libraries are in VC format, incompatible with djgpp. The DLL would be the most straightforward approach. I'm not looking forward to reiventing the entire API merely to use djgpp. Nor do I relish the notion of trying to do a real-time data display under Visual C. Under DOS with the old ISA card, it was a simple matter of accessing the memory map. Using a 486DX-2, the display was plenty fast enough. Under NT, accessing hardward is a good deal more involved, so it seems. Suggestions? Thanx Charles -- Charles Krug, Jr. Application Engineer Pentek Corp 1 Park Way Upper Saddle River, NJ 07458
