Seperate many txt file in SD
Hi everyone~ Thx~
And i want to ask a question about Seperate many txt file in SD.
Now i do is this picture. 
All data are in the same txt.
But what i want is "one value with one txt".
Example: sdtest1 has only "1" value .Next "1" will with stdtest2 ......
This is my code. Would someone can give me some point to solve this problem?
#include "mbed.h"
#include "SDFileSystem.h"
SDFileSystem sd(p5, p6, p7, p8, "sd"); // the pinout on the mbed Cool Components workshop board
Timer timer_w;
Timer timer_s;
int main() {
timer_w.start();
timer_s.start();
mkdir("/sd/mydir", 0777);
mkdir("/sd/mydir123", 0777);
while(1){
if(timer_w.read() > 2){
FILE *fp = fopen("/sd/mydir/sdtest.txt", "a");
if(fp == NULL) {
error("Could not open file for write\n");
}
fprintf(fp,"%d\r\n",1);
fclose(fp);
timer_w.reset();
}
}
}
Thx very much!
