کتابخانه chan برای FATFs
سلام
من میخواستم یه دیتایی رو روی یک میکرو اس دی 8 گیگ با کتابخونه chan بنویسم با میکرو stm32f107 ولی اصلا فایلی ایجاد نمیکنه
کد من روی میکرو اس دی 4 گیگ استفاده شده
میخواستم ببینم باید از ورژن خاصی استفاده کرد واسه میکرو اس دی های مختلف؟؟
کد من اینه:
#include "diskio.h"
#include "ff.h"
#include "stdio.h"
#include "bsp.h"
#include "ff_gen_drv.h"
#include "drivers/sd_diskio.h"
//printf init
struct __FILE { int handle;} ;
FILE __stdout;
FILE __stdin;
FILE __stderr;
int fputc(int ch, FILE *f)
{
while(!USART_GetFlagStatus(COM2,USART_FLAG_TXE));
USART_SendData(COM2,ch);
return ch;
}

};
void main(void)
{
