是这样的,有现成的stm32程序,然后完全仿照stm32程序,我又编写了个dsp程序,但是dsp死活不行,得到的波形就是这样,但是stm32可以的。总共就2个函数,一个初始化,一个读acc和gyr

您可以在此处找到有关 ST MEMS 传感器命名含义的描述性手册。在您的情况下,LSM6DS3TR 代表线性传感器模块,3 轴 AXL + 3 轴 GYR,数字,“S3”是此特定 IMU 的系列,采用卷带包装。

你好论坛和ST支持, 我想知道LSM9DS1的磁传感器是否经过工厂校准。目前,它看起来好像他们根本没有校准。尽管所有传感器都放置在同一块PCB上并且环境非常相似,但我测量的硬铁和软铁计算导致了截然不同的结果。如果他们经过校准,你可以验证一下吗?如果没有,是否有可能获得工厂校准的传感器,因此我必须每个PCB设计运行我的测量和校准因子而不是每个单元? 另一个问题涉及到:您能否提供一种工具来计算测量中的硬铁和软铁补偿因子(CSV文件)?到目前为止,我正在使用我在互联网上找到的免费工具,它工作正常,但只计算硬铁偏移量。另一个应该计算两者(硬和铁软效应)因子的工具无法处理每一组数据,有时我会得到想象的结果(这是一个MATLAB脚本)。 提前致谢#soft-iron#lsm9ds1#hard-iron以上来自于谷歌翻译以下为原文 Hello Forum and ST support, I was wondering if the magnetic sensors of the LSM9DS1 are factory calibrated or not. At the moment, it looks to me as if they're not calibrated at all. My hard and soft iron calculation from measurement leads to extremely different results, despite all sensors are placed on the same PCB and in very similar environments. Could you verify for me if they're calibrated or not? If not, is there a possibility to get factory calibrated sensors, so that I'd have to run my measurements and calibration factors only once per PCB design and not for every single unit? Another question relates to that: Can you provide a tool that calculates the hard iron and soft iron compensation factors from measurements (CSV file)? As by now, I'm using a free tool I found somewhere in the internet, which works fine, but only calculates the hard iron offset. Another tool which is supposed to calculate factors for both (hard & soft iron effects) can't handle every set of data, sometime I get imaginary results (it's a MATLAB script).

嗨,我正在试着理解我在电路板上为LSM9DS0读取的数据。如果我把电路板放在我的桌子上,根据数据表,我应该读取Z-AXIS的负值,因为Z-AXIS矢量指向上,而不是我读取1g的正值。 其他两个轴也是如此。 所有的读数都是倒置的吗?或者我错了什么?以上来自于谷歌翻译以下为原文 Hi, I'm trying to understand the readings I got for a LSM9DS0 on my board. If I hold the board on my desk, according to the datasheet I should read a negative value for the Z-AXIS, because Z-AXIS vector points up,instead I read a positive 1g value. The same happens with the other two axes. Are all the readings inverted? Or am I wrong with something?

请问怎样使用BSP_MOTION_SENSOR_GetAxes函数从传感器套件获取数据(陀螺仪+加速器)呢?

最近 3 天我一直在研究 esp01 和 mpu9250,尝试了很多库、库更改、代码更改,在我来的时候,当 imu 连接到引脚 0 和 2 时,使用基本代码,如获取 acc、gyr 和 mag 值
