پاسخ : مشکل با sim808 با STM32

کد برنامه ای که با اینتراپت نوشته بودم رو یک مقدار تغییر دادم الان جواب میده ولی باید بعد از هر پیام میکرو رو ریست کنم. فکر میکنین که مشکل از چی باشه ؟
کد برنامه اصلی :

کد:

#include <stm32f10x.h>
#include "usart.h"
#include <string.h>
#include <stdio.h>

#define CR       usart_sendchar('\r');

#define SUB      usart_sendchar(S);
