Hi guys, I need your help.
I'm currently creating a device that needs to do some operation with the sd card.
To be precise I'm building a gps chrono and I have to:
1)Read and write a settings file that is located in the main folder (I don't want to use the eeprom becouse hopefully this device will be sold and I want the ability to just send the settings file and just copy and paste);
2)Read information on previously written data (mainly gps coordinates and some other information);
3)datalogging (i need to keep track of all the times that were calculated by the main functions and store in a specific file in a specific folder that rappresent the varius tracks).
The main program (responsable of all the UI and the chrono part) is working fine but I need all the information acquired to be readible from my device (mainly) but also from the file (in case the rider wants to check all the times using the pc).
I saw that the possible solution would be the strtok function.
I used paython whenever i needed to work with strings becouse for me is much easier and I haven't really understood the token logic.
Can anyone solve my problem or give me an advice?
Thank to everyone,
any advice is appreciated.
