Generate 20 points per cycle for 10 cycles of a 100 hz sine wave

[Joe Aggie]

I need to generate 10 cycles of a 100 Hz sine wave with delta x being Pi/10 (20 points per cycle). I'm having a tough time keeping the timing since each point must be generated in .5 ms increments. 100 Hz = 1 sine wave per .01 seconds / 20 = .0005 seconds per point.

Thanks!

Please tell us what kind of hardware you are using and how you are sending your sine wave to it. 0.5 ms per point is too fast to do software timed updates on any desktop OS based system. You will need to send buffered data to a hardware timed system or use a real time OS.
