LSM9DS1磁力计的自检是否与LIS3MDL相同

问答对人有帮助，内容完整，我也想知道答案 0 我正在尝试在LSM9DS1传感器上测试磁力计。我可以应用与LIS3MDL指南针相同的自测范围值来检查LSM9DS1吗？事实是LSM9DS1中的磁力计似乎是LIS3MDL（寄存器的相同文档）。我正在使用 http://www.st.com/resource/en/application_note/dm00136626.pdf 第19页说明了自检程序，表17中给出了自检范围。我已经实现了LSM9DS1的自检程序，并且我在一个传感器上获得了该程序，我怀疑它有以下值： Average_X_self_test - Average_X_no_self_test = 2551（无比例）= 0,93高斯 Average_Y_self_test - Average_Y_no_self_test = 2682（无比例）= 0,98高斯 Average_Z_self_test - Average_Z_no_self_test = -415（无比例）= -0,15高斯对于第二个似乎没问题的传感器，值是： Average_X_self_test - Average_X_no_self_test = -4476（无比例）= -1,64高斯 Average_Y_self_test - Average_Y_no_self_test = -4473（无比例）= -1,64高斯 Average_Z_self_test - Average_Z_no_self_test = -515（无比例）= -0,19高斯在几次自测试中，值是一致的。如果我采用LIS3MDL应用笔记中提到的范围，则意味着第一个传感器坏了。感谢您的支持。最好，大卫＃lsm9ds1＃lis3mdl #magnetometer＃self-test 以上来自于谷歌翻译以下为原文 I am trying to test the magnetometer on LSM9DS1 sensors. Can I apply the same self-test range-values than the LIS3MDL compass to check the LSM9DS1? The fact is that the magnetometer in the LSM9DS1 seems to be a LIS3MDL (same documentation of the registers). I am using the http://www.st.com/resource/en/application_note/dm00136626.pdf , where the self-test procedure is explained in page 19, with self-test ranges indicated in table 17.I already implemented a self-test procedure for the LSM9DS1 and I obtained for one sensor on which I suspect a problem the following values: Average_X_self_test - Average_X_no_self_test = 2551 (no scale) = 0,93 gauss Average_Y_self_test - Average_Y_no_self_test = 2682 (no scale) = 0,98 gauss Average_Z_self_test - Average_Z_no_self_test = -415 (no scale) = -0,15 gauss And for a second sensor that seems ok, the values are: Average_X_self_test - Average_X_no_self_test = -4476 (no scale) = -1,64 gauss Average_Y_self_test - Average_Y_no_self_test = -4473 (no scale) = -1,64 gauss Average_Z_self_test - Average_Z_no_self_test = -515 (no scale) = -0,19 gauss Values are consistent on several runs of self-tests. And if I take the ranges mentioned in the application note of the LIS3MDL, it means that the first sensor is broken. Thank you for your support.

答案对人有帮助，有参考价值 0 大卫你好，如你可以使用的另一个线程中所提到的 http://www.st.com/content/ccc/resource/technical/document/application_note/69/d7/05/fe/a9/3e/4b/ea/DM00136626.pdf/files/DM00136626.pdf/jcr：内容/翻译/ en.DM00136626.pdf 用于LSM9DS1磁力仪自测包括极限。如果您提到的第一个传感器没有损坏，那么它至少是边缘的。注意，切赫以上来自于谷歌翻译以下为原文 Hello David, as mentioned in another thread you can use http://www.st.com/content/ccc/resource/technical/document/application_note/69/d7/05/fe/a9/3e/4b/ea/DM00136626.pdf/files/DM00136626.pdf/jcr:content/translations/en.DM00136626.pdf for LSM9DS1 magnetometer selftest including the limits. If the first sensor you mentioned is not broken than it's at least marginal.Regards, Petr
