如何让LSM9DS0 i2c工作？

我在使用LSM9DS0 iNEMO惯性模块进行i2c通信时遇到了麻烦。我已将它连接起来，但它没有响应who_am_i读取请求。我已经将SDO连接到1，所以使用默认的i2c地址0x3A，但我没有得到从机ACK信号。出于绝望，想知道我的地址是否错误，我查了每个i2c地址，但仍然没有发现任何响应。我尝试过100 kHz和400 kHz，结果相同。我也连接了不同的i2c传感器，它们工作正常，所以我知道我的其余部分工作。是否有任何技巧让i2c工作？

I'm having trouble getting i2c communications working with LSM9DS0 iNEMO inertial module.  I've wired it up, but it isn't responding to who_am_i read request.  I've wired SDO to 1, so am using your default i2c address 0x3A, but I'm getting no slave ACK signals.  Out of desperation wondering if I had the address wrong I pinged every i2c address, and still found no response.  I've tried 100 kHz and 400 kHz, same result.  I've also wired different i2c sensors, and they work fine, so I know the rest of my board works.  Are there any tricks getting i2c to work?
