All,

I'm working on a Beaglebone Black project using a MEMS accelerometer chip, 
the ADXL312.

The accelerometer has a pin which goes active each time a new data sample 
is available to be read.
It runs at 3200 Hz.  (about 1/3 of a ms per sample)

The pin is connected to a GPIO input and I've written code to monitor this 
pin and grab the data each time.
The sampling normally runs for several seconds continuously.

The problem is, every once in a while Linux gets busy and apparently 
interrupts my code and I miss samples.
(an overrun bit lets me know this is happening)


I'm looking for ideas on how to improve this so data samples are not missed.

Any ideas?

Kirk
