L3G4200 SPI不稳定读取值

你好


我正在尝试使用L3G4200D陀螺仪测量3维的音高。但是我遇到了一个问题：
我使用了Keil的例子。我使用SPI来读取和写入设备...我可以读取一些寄存器，例如WHO_AM _I等。我也使用了这些控制寄存器配置：

Gyroscope_Write（CTRL_REG1,0x0F）; / * ODR：100Hz，截止：12.5，* /
Gyroscope_Write（CTRL_REG4,0x00）; / *持续更新，满刻度250dps * /
Gyroscope_Write（CTRL_REG5,0x40）; / * FIFO启用* /

但是我无法读取状态寄存器（X，Y，Z）。我的问题是从陀螺仪读取的结果在任何方向都没有移动的地方都不稳定！

请帮我解决这个问题，如果你能给我一些有用的代码示例，那将会很棒。

感谢您的关注，

Hello


I'm trying to use the L3G4200D Gyroscope to measure the pitch in 3 dimention.But I faced a problem with:
I used the Keil's examples.Iuse SPI to read and write on the device...I can read some registers such as WHO_AM _I  etc. I also used these control register configuration:

Gyroscope_Write(CTRL_REG1, 0x0F);     /* ODR: 100Hz, Cut-Off: 12.5,         */
Gyroscope_Write(CTRL_REG4, 0x00);     /* Continuous update,full scale 250dps*/
Gyroscope_Write(CTRL_REG5, 0x40);     /* FIFO Enable                        */

But I can't read state registers(X, Y, Z).My problem is that the result read from the gyroscope is not stable at all where it is not moving in any direction!!!

Please help me to solve the problem and it would be great if you can provide me some working code examples.

Thank you for your attention,
