你好,何塞,
我已经向论坛发送了回复,但多亏了“精心设计的”ST页面没有发送任何内容,整个工作都没有了。所以从头开始。
我不是Raspberry的专家,但I2C无处不在。我会尽力回答这个问题。
您可以从ST web下载MKI159V1的原理图和LSM9DS1的数据表。
MKI159V1 Pin Raspberry GPIO引脚
13 9(GND)
1,2,18,19,23 1(直流电源3.3 V)
22 1或9(I2C地址选择,参考数据表)
20 5(I2C SCL)
21 3(I2C SDA)
20将电阻3k3上拉至引脚1
21上拉电阻3k3至引脚1这是最小配置。
如果你想使用Raspberry通知的中断,你还必须将MKI159V1引脚14..17连接到Raspberry的GPIO引脚。我希望这会有所帮助。
最好的祝福,
玛丽安

Hello Jose,
I already send response to the forum, but thanks to ''well-designed'' ST pages nothing was send and whole work is gone. So again from scratch.
I am not an expert for Raspberry, but I2C is the same everywhere. I will try to answer the question.
You can download schematic for MKI159V1 and datasheet for LSM9DS1 from ST web.
MKI159V1 Pin Raspberry GPIO Pin
13 9 (GND)
1,2,18,19,23 1 (DC power 3.3 V)
22 1 or 9 (I2C address selection, refer to datasheet)
20 5 (I2C SCL)
21 3 (I2C SDA)
20 Pull-up resistor 3k3 to pin 1
21 Pull-up resistor 3k3 to pin 1This is the minimal configuration.
If you want to use interrupts for Raspberry notification you have to still connect MKI159V1 pins 14..17 to GPIO pins of Raspberry.I hope that this will help.
Best Regards,
Marian
