- Hi,
- I'm working on writing an interface for the SoundBlaster on a Mach
- machine. While DMA is obviously the way to go, I am also interested in
- how to do a non-dma interface to the DAC. Specifically I need to know.
-
- 1. is there an internal FIFO buffer I can write to and , if so,
- a. How can I write to it?
- b. how can I get the status on how full it is.
-
- If anyone has any technical specs (or public domain code) on this aspect
- of the card (or any other for that matter), please let me know. I am in
- the process of ordering the developers kit, but I would like to get some
- things done now. I have looked around the ftp sources listed in the FAQ,
- but have had no luck in finding this info. Also, I have heard of , but
- not seen Sblast_BSD_1.4 (a Sound Blaster BSD Unix device driver by
- Steve Haehnichen). If I could get a pointer to that, I would appreciate
- it.
-
- Thanks in advance,
- Tom N.
