无法启用中断模式

问答对人有帮助，内容完整，我也想知道答案 0 嗨，我正在研究一些运动检测产品。选择LIS2HH12作为运动检测器。我们想在中断模式下使用它。不幸的是，我们没有在INT1引脚上获得任何信号，用o观察 scilloscope 。真可惜T_T.My的配置顺序如下，您能帮忙提一些建议吗？ //启动检查SPI总线 GSENSOR :: LIS2HH_set_mode：WHO_AM_I = 41 [spi] //重置芯片 GSENSOR :: LIS2HH_set_mode：RESET //读取regs以检查重置状态 GSENSOR :: LIS2HH_set_mode：STATUS = FF [spi] GSENSOR :: LIS2HH_set_mode：CTRL5 = 00 [spi] // setup GSENSOR :: LIS2HH_set_mode：CTRL1 = 3F [spi] GSENSOR :: LIS2HH_set_mode：CTRL2 = 00 [spi] GSENSOR :: LIS2HH_set_mode：CTRL3 = 09 [spi] GSENSOR :: LIS2HH_set_mode：CTRL4 = 04 [spi] GSENSOR :: LIS2HH_set_mode：CTRL5 = 00 [spi] GSENSOR :: LIS2HH_set_mode：CTRL7 = 0C [spi] //检查 GSENSOR :: LIS2HH_set_mode：STATUS = FF [spi] GSENSOR :: LIS2HH_set_mode：INT_SRC1 = 25 [spi] GSENSOR :: LIS2HH_set_mode：INT_SRC2 = 00 [spi] GSENSOR :: LIS2HH_set_mode：STATUS = FF GSENSOR :: LIS2HH_set_mode：val [0] = -437，x = -26.657000 mg GSENSOR :: LIS2HH_set_mode：val [1] = -169，y = -10.309000 mg GSENSOR :: LIS2HH_set_mode：val [2] = -16427，z =-1002.047000mg♯♯ #interrupt-driven＃lis2hh12 以上来自于谷歌翻译以下为原文 Hi, I am working on some motion detection product.

答案对人有帮助，有参考价值 0 对您的评论配置： - GSENSOR :: LIS2HH_set_mode：CTRL3 = 09 [spi] ...使能INT1引脚上的中断发生器1和DRDY（不好混合两个信号） - GSENSOR :: LIS2HH_set_mode：CTRL7 = 0C [spi] ...在INT2中启用中断发生器1和FIFO为空（为什么???） - 缺少中断发生器配置IG_CFG1，IG_THS_X1，IG_THS_Y1，IG_THS_Z1，IG_DUR1 所以我建议从以下配置开始： CTRL1 = 0x3F // 100Hz，X，Y，Z使能，BDU使能 CTRL2 = 0x02 //为中断发生器1启用高通滤波器。要检测运动，只需要改变加速度。 CTRL3 = 0x08 //在INT1中启用中断发生器 CTRL4 = 0x04 CTRL5 = 0x00 CTRL7 = 0x00 IG_CFG1 = 0x2A //中断条件X或Y或Z高于阈值 IG_THS_X1 = IG_THS_Y1 = IG_THS_Z1 = 0x0D //将阈值设置为100mg（根据需要调整） IG_DUR1 = 0x0A //将持续时间设置为100ms（根据需要调整）以上来自于谷歌翻译以下为原文 Comments to you configuration: - GSENSOR::LIS2HH_set_mode: CTRL3 = 09 [spi] ... enables Interrupt generator 1 and DRDY on pin INT1 (not good to mix the two signals) - GSENSOR::LIS2HH_set_mode: CTRL7 = 0C [spi] ... enables Interrupt generator 1 and FIFO empty in INT2 (why ???) - Missing interrupt generator configuration IG_CFG1, IG_THS_X1, IG_THS_Y1, IG_THS_Z1, IG_DUR1 So I recommend to start with following configuration: CTRL1 = 0x3F // 100Hz, X,Y,Z enable, BDU enable CTRL2 = 0x02 // High pass filter enabled for Interrupt generator 1. To detect a motion only change in acceleration is needed. CTRL3 = 0x08 // Enable interrupt generator in INT1 CTRL4 = 0x04 CTRL5 = 0x00 CTRL7 = 0x00 IG_CFG1 = 0x2A // Interrupt condition X or Y or Z is above threshold IG_THS_X1 = IG_THS_Y1 = IG_THS_Z1 = 0x0D // Set the threshold to 100mg (adjust according to you needs) IG_DUR1 = 0x0A // Set duration to 100ms (adjust according to you needs)
