Hi All, 

I am under development of a capture system. I need to sample about
200Hz. That is, about sampling each 0.005 seconds.

I have it working using the Jim Jackson's adc_logger.

Unfortunatelly, this can't accomplish the job as it's accurate about 10ms.

So, I decided using gettimeofday. Oh surprise!!! It doesn't work
properly. microsecond precision? Forget about it. Readings give me
mumbers like this:

510000
530000
550000

It sounds like 10msec precision.

Next step, checking the TS7000 group. I downloaded the file:
linux24_ts8-lck1-cpufreq-230705.patch.gz

I have a ts11 version. Will this work?

A noob question: How to have this working? I suppose using the "patch"
command. I ran "patch -p0 lin.......". By the time I am writing this,
the command is still running without showing any message.

If this command finishes, what will be the outcome? Having the
"gettimeofday" working properly?

Can I get cpu ticks or something like that in order to have the real
microsecond precision?

Regards.
