首先感谢网上朋友们的分享，我也贴出自己的源码，开源互助！ 1、配置：可以换一个引脚，不知道为什么，总是要开始PC8和PC9相同配置，单片机才能进入中断，应该是单片机问题； //ÖжÏÅäÖà ADXL345_WriteByte(DATA_FORMAT , 0x29); delay345_ms(200); //Êä³öµÍµçƽÖжϣ¬13bit·Ö±æÂÊ ADXL345_WriteByte(BW_RATE , 0x09); delay345_ms(100); //Õý³£¹¦ÂÊ 50HzÊä³ö ´ø¿í25Hz ADXL345_WriteByte(POWER_CTL , 0x00); delay345_ms(100); //½øÈëstandby mode ADXL345_WriteByte(POWER_CTL , 0x28); delay345_ms(100); //²âÁ¿Ä£Ê½ ²»»á×Ô¶¯Ë¯Ãß //Öжϵ͵çƽ ADXL345_WriteByte(INT_ENABLE,0x00); delay345_ms(200); //¹Ø±ÕÖÐ¶Ï ADXL345_WriteByte(0x24,0x02); delay345_ms(200); //¼¤»î˯ÃßactivityãÐÖµ,´óÓÚʱ´¥·¢Öжϣ¬2 - 2g ADXL345
