How to create a new file?

Hi
I run a modified version of MCstackDemo2.
I would like to ad a type of log file to the webserver. If the log file dosent exist it should be created.
Have anybody tested something like this?

No, haven't tried yet, but writing files to the SD card is something that I will want to do ( when I get to that bit ).

If you've configured UART 1correctly, and are able to send data back to a PC using printf() - that is, you've created an implementation of _mon_putc(char c ), something like so:
Code: [Select]
void _mon_putc(char c){
while(U1STAbits.UTXBF == 1); //if buffer is full, wait
    U1TXREG = c;
}

Then you could log requests to the serial port by simply adding printf() statements in the SM_HTTP_PARSE_REQUEST switch case in HTTP2_MDD.c
Once that's successful, it should be a short jump to writing it to a file instead ( swap printf() from stdio.h to FSvfprintf() from FSIO.h )
