If you only want to store one file, one trick is to format the memory card and write a file full of 0xff's to the card whilst connected to the PC. Find out the starting cluster and start writing your data from this point as FAT allocates the clusters sequentially. To read your file on the PC is as simple as reading the file! However, the remaining part of the file is full of 0xff's. You can write a simple program in your language of choice on the PC to remove these. So you get the advantages of a file system without the code overhead on your micro. Actually, if you only want to write a text file, fill the file with 0x1a's which are an end of file marker (methinks). |
