USB as a V drive for pendrive

Hi,

I want to implement a USB module as V drive for pendrive where I can get commands through uart such as make directory ,open file etc and then dump the file onto pendrive. I am aware of how USB works, I want to know the feasibility of this project and a starting guide to how can it be achieved.

  • Hi,

    Thanks for the response. I am almost done with everything on file handling, but i am facing some issues with writing to files from command line.
    Before creating a file i have to check whether it is created or not.
    Once I get this info I write the text from the command line to the file.
    Now this is where i face the problem.
    Here I copy the arguments to temp buffer and then i use f_write function.
    Instead should I use f_printf function here will it work.
    Also if I want to write to a file in between how can i do this, I know i have to use lseek function but how.

    My command would be something like this

    wrf hello.txt hello all, this is fatfs world

    any suggestions
