Yes I've started looking into the examples but, there are no examples for using the USB. They're all related to storing it in the SD card. Actually today I tried connecting USB to my Eval board and it did show up as a USB device when I connected it to a computer. My target is to make a .text file (more like a log) which shows up in that USB connection which I made.
Also, I do plan to store it in the RAM for now at least. I took an example code from http://elm-chan.org/fsw/ff/doc/open.html. It is as follows:
/* Read a text file and display it */
FATFS FatFs; /* Work area (filesystem object) for logical drive */
int main (void)
{
FIL fil; /* File object */
char line[100]; /* Line buffer */
FRESULT fr; /* FatFs return code */
/* Gives a work area to the default drive */
f_mount(&FatFs, "", 0);
/* Open a text file */
fr = f_open(&fil, "message.txt", FA_READ);
if (fr) return (int)fr;
/* Read every line and display it */
while (f_gets(line, sizeof line, &fil)) {
printf(line);
}
/* Close the file */
f_close(&fil);
return 0;
}
The problem is, I'm not able to locate the message.txt file. Where is it? Looking at the disassembly, it shows that it is in the Flash but, how can I access it? I want to make a flash file that first shows up in let's say the folder where my project source code is for example. Next step would be to try and get it to store in the USB. How should I proceed? Any ideas?
