Chibios和SIM900 Shiled

Question

我有这个问题， 我有STM32 Nucleo L152RE和Shield SIM 900， 现在，如果我写这个简单的线程一切正常，

ORDER BY date_added

＆＃39; 当我打电话给AT commnad时，我看到了正确答案。 现在我创建这个缓冲区

'static THD_WORKING_AREA(waRead, 128);
    static THD_FUNCTION(Thread,arg) {
     (void)arg;
     chRegSetThreadName("th_callback");
   while (TRUE){
    /* This will wait for a character to be received */
    uint8_t c = sdGet(&SD1); //questo prende il carattere
    sdPut(&SD2, c);  // questo lo spara alla terminale
     } 
    }

我用这个帖子来存储答案

'static  uint8_t bufferMsg[128];'

这个线程没有工作，也没有存储答案，你能帮帮我吗？

最好的问候 甲

Answer 1

我使用，

定义

select owner_obj_id,
       ddr_medium_id,
       case when count(ddr_medium_id)>1 then 'Duplicate' else 'Unique' END As Dup_Check
from yourable
group by owner_obj_id,ddr_medium_id

功能

#define buffer_size 128
char buffer[buffer_size + 1];
int nbytes = 0;

主要

void SIM_callback(){             /*  GSM900 Serial */
    char x = SIM.getc();   
    buffer[nbytes] = x; 
    nbytes++; if (nbytes > buffer_size) nbytes = buffer_size;
    buffer[nbytes] = '\0';  
}
