- Hi !
-
- I'm currently buildiing a data acquisition system which uses the parallel
- port do digitize audio signals. The A/D, D/A are both 16 bit devices and
- I am currently reading and writing a nibble at a time. I have achieved a
- sampling rate of "about" 32KHz, although I am looking for a way of keeping
- the sampling rate constant. I have tried using PIN 10 'acknowledge' input
- pin which sets IRQ7 with no luck at all. Can anybody out there please help
- me set up this interrupt and use it. I'm using Turbo C v2.0, but any source
- code would be appreciated.
