在ccsv5中怎么查看程序运行时间，以及从那可以方便的知道430集成库里的函数例如——延时函数，低功耗函数等
你好，
关于运行时间，CCS这点没有KEIL好用，没有一个现实时间的窗口，你要了解一段程序跑了多久，可以在程序开始驱动GPIO高电平，在程序结束驱动GPIO低电平，通过示波器抓时间宽度。
关于延时和低功耗你可以参考msp430xxx.h文件：
/* Low Power Modes coded with Bits 4-7 in SR */
#ifdef __ASM_HEADER__ /* Begin #defines for assembler */#define LPM0 (CPUOFF)#define LPM1 (SCG0+CPUOFF)#define LPM2 (SCG1+CPUOFF)#define LPM3 (SCG1+SCG0+CPUOFF)#define LPM4 (SCG1+SCG0+OSCOFF+CPUOFF)/* End #defines for assembler */
#else /* Begin #defines for C */#define LPM0_bits (CPUOFF)#define LPM1_bits (SCG0+CPUOFF)#define LPM2_bits (SCG1+CPUOFF)#define LPM3_bits (SCG1+SCG0+CPUOFF)#define LPM4_bits (SCG1+SCG0+OSCOFF+CPUOFF)
#include "in430.h"#include <intrinsics.h>
#define LPM0 _bis_SR_register(LPM0_bits) /* Enter Low Power Mode 0 */#define LPM0_EXIT _bic_SR_register_on_exit(LPM0_bits) /* Exit Low Power Mode 0 */#define LPM1 _bis_SR_register(LPM1_bits) /* Enter Low Power Mode 1 */#define LPM1_EXIT _bic_SR_register_on_exit(LPM1_bits) /* Exit Low Power Mode 1 */#define LPM2 _bis_SR_register(LPM2_bits) /* Enter Low Power Mode 2 */#define LPM2_EXIT _bic_SR_register_on_exit(LPM2_bits) /* Exit Low Power Mode 2 */#define LPM3 _bis_SR_register(LPM3_bits) /* Enter Low Power Mode 3 */#define LPM3_EXIT _bic_SR_register_on_exit(LPM3_bits) /* Exit Low Power Mode 3 */#define LPM4 _bis_SR_register(LPM4_bits) /* Enter Low Power Mode 4 */#define LPM4_EXIT _bic_SR_register_on_exit(LPM4_bits) /* Exit Low Power Mode 4 */#endif /* End #defines for C */
关于延时，你可以参考
先做如下预定义： #define CPU_F ((double)8000000) #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)) 其中第一行中的8000000为时钟，可以根据自己时钟设置。 然后在程序中直接条用delay_us和delay_ms即可。非常好用，入： delay_ms (1); //延时1ms delay_us(1); //延时1us delay_us(0.125); //延时0.125us
