没有 这是初始化后数据寄存器的原始数据

littleshrimp 发表于 2020-6-2 11:12 这个驱动是ST官方的 我没有这个板子没实际测过 不过ST那边应该是测试过的 你使用的是read data simple.c ...

是的

littleshrimp 发表于 2020-6-2 09:35 先读一下WHO_AM_I(0F)看一下是否正确，排除通信问题。

WHO AM I寄存器读出来的值是0x33 没有问题 就是使用的您上传的驱动

你好 使用了这个封装之后  我发现在成功读取到状态寄存器STATUS_REG (27h)的ZYXDA标志为1之后读取出来的加速度数据均为0  请问您知道是什么原因吗

可是我实际测试的时候，发现每秒钟只能输出三百多个三轴加速度数据。

请教一个问题，比如ST的三轴加速度传感器的ODR设置为952HZ，这是不是表示三个轴每秒能同时刷新952个数据，而不是每秒三个轴加起来共同刷新952个数据。

maychang 发表于 2019-7-24 17:53 在你的加速度计静止时读数，然后将此数值在测量后扣除，是否可以行得通？

行不通，加速度计一旦姿态和空间位置发生变化，还是会有重力分量的影响。

littleshrimp 发表于 2019-7-25 11:26 st的open mems的MotionFX库里有linear acceleration的东西，你也可以试一下   float linear_accele ...

我想只利用加速度计消除重力加速度的影响，不结合图陀螺仪和磁力计。

请问为什么我用同样的方式利用中断读取数据，中断只能进入一次，下面是我的配置代码：   lsm9ds1_pin_int1_route_t lsm9ds1_pin_int1_route;   lsm9ds1_pin_int1_route.int1_ig_xl = 1;   lsm9ds1_pin_int1_route.int1_drdy_xl = 1;   lsm9ds1_pin_int1_route_set(&dev_ctx_imu, lsm9ds1_pin_int1_route);

littleshrimp 发表于 2019-5-31 16:22 你需要有一个单片机，连接传感器，把数据通过spi或者i2c读到单片机里，然后再做处理。

这个已经做过了  就是不知道读到单片机之后怎么进行数据采样和FFT分析   处理之后又怎么进行验证  需要什么硬件或软件环境

littleshrimp 发表于 2019-5-30 10:57 这个需要你采集数据后再计算

如何采集数据并计算  请问需要用到什么软硬件
