LSM9DS0 4线SPI通信MCU无法得到任何响应

嗨，大家好

我正在使用STMEVAL-MKI109V2进行LSM9DS0，使用4线SPI通信？如果在EVAL板上电后保持CS_G = 0且CS_XM = 1，但在CS_G = 1和CS_XM后CS_G = 0，则读取陀螺仪的WAI reg是正常的= 1，读取WAI reg，MCU无法得到任何响应（SDO = 0xFF总是），有人可以解释一下为什么？如果有人能发布LSM9DS0 SPI通信代码，我将不胜感激。
谢谢。

hi,guys

I'm working on LSM9DS0 with STMEVAL-MKI109V2,using 4-wire SPI communication?read gyro's WAI reg is ok if keep CS_G=0 and CS_XM = 1 after EVAL board power on, but if CS_G=0 after CS_G=1 and CS_XM = 1,read WAI reg, MCU can't get any response(SDO=0xFF always),can anyone explain me why? I would be grateful if anyone could post LSM9DS0 SPI communication code.
thanks.
