LSM9DS0陀螺仪阅读问题

问答对人有帮助，内容完整，我也想知道答案 0 我有一个LSM9DS0，我正在尝试运行。我的I2C工作正常，因为我可以读取两个WHO_AM_I寄存器的正确值。我还可以读回一个控制寄存器，读取的数据与写入的内容相匹配。陀螺仪读数不稳定，看起来不正确。我在fifo旁路模式下运行。我通过控制寄存器禁用了两个轴，这些轴继续更新和移动。我认为禁用轴不会有任何更新。我正在使用0x80的函数寄存器进行多字节读取，我相信I2C正在工作。禁用轴是否应该在我身上移动？是否有任何可能导致此类行为的配置项？谢谢，约翰＃I2C-lsm9ds0 以上来自于谷歌翻译以下为原文 I have a LSM9DS0 that I am trying to get operational. My I2C is working since I can read the correct values for both WHO_AM_I registers. I can also read back a control register and the data read matches what was written. The Gyro readings are not stable and don't look correct. I am operating in fifo bypass mode. I've disabled two of the axes via the control register and those axes continue to update and move around. I would think that there would not be any updates to a disabled axis. I am oring the function register with a 0x80 for a multibyte read and I believe that the I2C is working. Should the disable axes be moving on me? Are there any configuration items that can cause this kind of behavior? Thanks, John #i2c-lsm9ds0 0

答案对人有帮助，有参考价值 0 我有类似的问题。陀螺仪具有恒定的值。所有3个轴都打开但它们保持不变。甚至连加速输出都会发生这种情况。通常打开/关闭设备会解决它。我不知道如何解决它。我希望ST的某些人可以提供帮助。以上来自于谷歌翻译以下为原文 I've got a similar problem. The gyro has just constant values. All 3 axes are on but they stay constant. That even happens from time to time with the acceleration output. Usually switching the device on/off resolves it. I've got no idea how to resolve it. I was hoping somebody from ST could help.
