哪位高手教教我，怎么用IAR的调试功能调试出每条指令所用的时间啊？我想算出非常精确的时间....   我现在用的是msp430f149.我是新手，谢谢！

Lijin

高手大哥大姐们，求救啊！！

Lijin

是不是高手们都觉得这个问题很幼稚啊？

#define CPU_F ((double)1000000)
#define delay_us(x) __delay_cycles((long)(CPU_F*(double)x/1000000.0))
#define delay_ms(x) __delay_cycles((long)(CPU_F*(double)x/1000.0))
用这个吧

__delay_cycles（）
在intrinsics.h 里
