#104927 - EISA Bus interfacing Responding to: ???'s previous message |
Hi Suresh,
Actually, the software complexity depends on several factors: Level of software complexity is ordered from most to least: 1.) Do I need to use Direct Memory Addressing (DMA)? 2.) Do I need the PC's interrupt request line (IRQ)? 3.) I assume by stating EISA you need 16-bit data path? 4.) How is my I/O card 'mapped' in the I/O memory space? Try a google search on someone's 'pet project', this may prove useful to you (: I designed and built my own ISA cards around ten years ago - and talked to them with Borland C (lots of fun!), but I cannot remember circuit details, sorry :( Cheers, Valentin [edited post] |
