[Newbie help] Problems with creating multiple different files using FATFS [Copy link]

Hey guys, here are the questions:

1 For a file, follow the order of “mount workspace + open and create file + write data to file + close file + close workspace”.

2 During the operation of this file, no operation is performed on other files.

3 The problem is: at each moment when we need to record, we need to create a new file to record the data, using

res = f_open( &fsrc , "A000001", FA_OPEN_ALWAYS | FA_WRITE); to create a new file

4 FATFS says that one file corresponds to one FIL variable. In this scenario, there will be a lot of FILs. I don’t know how to handle FILs.

Do you have any reference examples? Thank you . I have been searching for a long time but couldn't find any.

Problem Solved

Experimental results show that in the process of "open workspace + open file + write file + close file + close workspace", as many FIL files are needed as there are txt texts. However, after this process is completed, the FIL variables used in the previous process can also be used in the subsequent files. Note that the file name char array should be changed before opening the workspace.

Just record them differently.
