Timing of the FILE-Functions

A. M. over 15 years ago

Hello everybody,
Are there any Timing Diagramms of the FILE-Functions in KEIL (Example: fflush, fopen...)?
How fast are these Functions?

Thanks a lot!

Wouldn't that be too dependent on the underlying medium?

Execution time depends on the medium being address - RAM drive, SD card, NOR flash, file system complexity etc. How about measuring?

Hi,
It would, your're right. It depend also by frequency, so I need to give more information. But I just need the Diagramm for comparing with my Functions.

I need the LPC2148 ARM7TDMI-S, 15MHz Clock on the SD-Card.

Thanks

Again - is there anything that stops you from actually measuring it? do you have a scope? surely you can use a hardware timer for that, too!

I am measuring, but I'd like to compare with a Diagramm. It would be very nice if I could make some adaptions etc.
I'm just trying out...

PS: I'm measuring with a digital oszilloscope.
