Freematics Forum

I've been working with the Vehicle Data Logger and trying to get it to actually log data onto an SD card.

Working with the datalogger arduino project on https://github.com/stanleyhuangyc/Freematics (firmware_v2), I never was able to get the datalogger project to actually record data on an SD card. If I used the pre-compiled hex files at https://sourceforge.net/projects/obdcon ... reematics/, data was recorded.

My question is - why was one working and the others did not?

Thanks

delete line 11 in OBD.cpp and it should work....

at least for me it did (without logging GPS)

I haven't reprogrammed my datalogger as purchased. I don't get a .csv log file on the SD card when I plug it into my car though. I formatted the SD card to FAT, but do I need to create a specific file name or folder?

This seems like a very simple question and I apologize for my ignorance.
