Hello,
I'm using a sainsmart mega2560 and a LC studio SD module:
and a GPS shield and OBD TTL Adapter.
I have it connected and coded to store OBD data and GPS data in a datalogger type of setting.
My only concern now is that if it ever gets full, does it simply stop saving?
I've read in some forum threads that it's simply done through copying from one record, then deleting everything but saving only the remaining record from the previous text file needed
But I've seen other threads doing something like, only 100+ records per text file, then deleting the oldest record by date (or name).
I'm only starting my methods before actually coding the overwrite but I already saved records from my gps and obd to the sd card, I just wanted to ask for advice when it comes to file size.
Because I'm making a sort of Event Data Recorder, but recording for the entirety of the journey and that 32gb is, from my calculation, can be easily filled within 5.6 days(Continuous) both with OBD and GPS record.
Thank you for sparing time to read my question.
