Ok, i'm not sure if any of you guys have had experience with Hardware and Software I/O interfacing. But none the less, I'll give this a shot. I'm working on a fairly simple project involving a ADC0809 ( analog to digital convertor) It requires a 640 KHz clock pulse. Of course it can be supplied using a tripple 5 timer etc, but I want to use a software method.
I'm using Borland C 2.0 for DOS
It has a delay() function already predefined in it. the problem is, the period of this pulse if less than 1 ms.
Any solutions will be appreciated, thank you. If maybe U need me to tell u how this specific adc functions, just ask.
