I use a speeduino 0.4 with a mega.
Secondary serial is used to run a digidash so is already in use.
I'd like to find an easy way to data log on a semi permanent basis, IE the data will log all the time.
I see various options from searching but most threads are unfinished or missing info.
What would be my best option to achieve this? I really don't want to have a pi with tunerstudio running just to log .
I have a teensy 3.5 here so could I get an adapter board and run that in place of the mega and use the onboard SD or is that a dropbear only option?
Thanks in advance
