Hi,
I have recently begun looking at utilizing iio for the input part of a
robotics system but have some doubts about its usability for which I
would like your comments.
Today we have (in our embedded system) a number of custom written
drivers interfacing SPI attached accelerometers and AD converters,
utilizing hrtimers for software triggering of sampling at 50 to 250 Hz.
Herein lays my current question, has anyone used the IIO system with
these type of sampling rates? The RTC based trigger seems to only give
second or higher intervals.
I will be looking at converting our special drivers to be acceptable for
upstream submission, same for a hrtimers based trigger, should that be a
good idea.
Best regards
Marten Svanfeldt
