Last week we launched a rocket, in which an Arduino saved the data of the sensor in a csv file. Every 30s the programme used myFile.close()
and a new file was created.
But even if the chute deployed, the SD disconnected when the rocket touched the ground so the file was never closed. So I lost up the 30s of flight data and I would like to recover at least a part of it.
I have the file but it is empty.
It is worth noting that each file was 60Mo and my RAM was 8Mo (teensy 4.1) so I know that at least part of the data is in there.
Does someone know a software that could save my data?
