If you need source code for the Metrabyte DASH-16, drop me a line and
I'll send it to you. Conversion rates up to 20..40 kHz depending on
CPU speed. Compiles with TurboC 2.0 and DJGPP 1.11m5. Uses simple polling
(no DMA).
On the other hand, I would be interested in src code for
- Tecmar Labmaster
- Data-Translation DT2821
Please let me know if you have it available.

Impact of gcc -O? optimisation ?

Hope this helps
