Hey all! I am wanting to create a .CSV file in C via a microcontroller (S08JM60 to be exact). I was wondering if there's anything special that I have to do to make it work, or if there's a UML Diagram of what to do for it. Because I have a feeling that it's a standardized file type. Any help is greatly appreciated! EDIT: If you want to know the specifications, I am grabbing sensor data every 30 seconds, so I want to be able to store the file once there is no power running to it. I plan on having a small battery backup to it to keep it powered to store the data when the device is unplugged.
