How to implement short and accurate delays for CVI?

[Lassi Stenroos]

I am implementing I2C control software for CVI. I have to implement short (around 100 us) and accurate delay for that purpose. The delay should work well and equally in all PCs (different clock frequencies). Minimum delay for delay(?) function is 1 ms and it is too long.

I don't think you can achieve such resolution by software only.
You could look at multimedia timers that are the fastest and surest timing resources in Windows (they are used in CD reproduction and so on...), but in my opinion you should look at timing cards (also available at NI).

I've written extended driver routines for I2C and SMBUS devices using the British "Calibre ICA-90 I2C Card". As I do not see your e-mail address, I offer you to contact me via my address for extended exchange of ideas:
