首先电脑能识别430，写好的程序也下载进去啦，断电后再想烧程序，软件已经无法识别，提示could not find device,程序如下#include "msp430x21x2.h"void Init_Clk(void);//void  InitPIN(void);void InitADC10(void);void OpenADC10(void);void key_num(void);void low_cut(void);void db_decay(void);void m_direct(void);void big_signal(void);void pwm(unsigned int,unsigned int);//unsigned int dec,unsigned int dir)void inv_voltage(void);void Delay(unsigned short time);unsigned int ad_value[8],dec=200,dir=200,c_dec,c_dir;unsigned char v1[5];unsigned char v2[5];unsigned char direct=1,decay=1, cut=1;unsigned char key=0,key0=0,key1=1,key2=2,key3=3,key4=4,key5=5,key6=6;void main(){   //Init_Clk();  P3DIR |=0X7F;  P1DIR |=0X07;  P1DIR |=0X20;  P3OUT =0X00;  P2DIR |=0X20;  InitADC10();  Delay(1);  //pwm(dec,dir);      for (;;)  {   OpenADC10();    //inv_voltage();    key_num();   low_cut();   db_decay();   m_direct();   big_signal();
   }}


void Init_Clk(void){ unsigned int i ; WDTCTL = WDTPW + WDTHOLD;   BCSCTL1 |= XT2OFF; do     {    IFG1 &= ~OFIFG; // 清除OSCFault标志    for (i = 0xff; i > 0; i--);     }    while ((IFG1 & OFIFG) != 0); // 如果OSCFault =1  BCSCTL2 |= SELM_1; }
下载的是这个程序，我把初始化  //Init_Clk();给去掉了，看门狗没有停掉，可这也不至于JTAG口识别不了msp430f2122吧,现在片子无法识别，真是麻烦呀～～请大家帮帮忙～～大家都没有出现第一次软件能识别，等把程序烧进去之后无法识别430的情况吗？？？？
