LSM9DS0 I2C的问题

我正在使用LSM9DS0有线与I2C通信。芯片似乎能够识别它的被寻址，ACK字节，响应读取等，但问题是它总是发回相同的字节。例如：我尝试按以下顺序配置设备：

0xD4 0x20 0x7F 0x04 0x08 0x00 0x40


其中D4是陀螺仪地址，20是起始寄存器。然后，我执行5个字节的读取，以确保设备配置为我希望它，但只接收5个0x40实例。该模式似乎是写入寄存器的最后一个字节只是由芯片反复重复。唯一的例外是读取按预期响应的WHO_AM_I寄存器。

有没有其他人有这个问题或有任何想法可能会出错？

I'm using a LSM9DS0 wired to communicate with I2C. The chip seems to recognize when its being addressed, ACKs bytes, responds to reads, etc. but the problem is it always sends the same byte back. For example: I attempt to configure the device through the following sequence:

0xD4 0x20 0x7F 0x04 0x08 0x00 0x40


where D4 is the gyro address and 20 is the starting register. I then perform a read of 5 bytes to ensure that the device is configured as I want it to be but receive only five instances of 0x40. The pattern seems to be that the last byte written to a register is simply repeated over and over by the chip. The only exception is when reading the WHO_AM_I registers which respond as expected.

Has anyone else had this problem or have any ideas as to what might be going wrong?
