Data Acquisition Rate
I'm starting a datalogger project to record suspension position on my dirtbike and looking for the right DIY platform.
From what I've found and read the Arduino with the Ultimate GPS logger could be a good pick, however, there are a few critical questions that I've yet to be able to find an answer to.
My goal is to be able to log at least 2x analog channels that will have position sensors on them, plus the GPS position.
What is the max logging rate to the SD card for the GPS logger, it looks like 5 or 10hz is feasible?
Does the Ultimate GPS logger shield support logging additional analog inputs to the SD card too? If so how many and what rate can the inputs be logged at? Ideally I would like to log at ~500hz+ for the analog inputs. All I've been able to find on people using the Arduino and logging to a SD card has been at slower rates such as 1 or 5hz.
Any help on the subject would be great!
