是否可以使用没有STEVAL-MKI109V2的STEVAL-MKI142V1?

嗨,
我正在尝试用我的STM32nucleoF411RE测试我的I2C连接,但我似乎没有任何来自我的MKI142V1的响应。我已经测试了启动条件并发送了地址,但它似乎没有检索传感器应该发送回的确认位。
所以我的问题是,我可以真正测试没有MKI109V2的MKI142V1吗?

Hi,
I am trying to test my I2C connection with my STM32nucleoF411RE but I can't seems to have any response from my MKI142V1. I have tested the start condition and sending the address but it doesn't seem to retrieve the acknowledge bit that the sensor should send back.
So my question is, can I really test the MKI142V1 without MKI109V2 that everyone recommends ?

是的你可以。 STEVAL-MKI142V1只是一个转接板,您可以查看原理图

不要忘记将Vdd和Vdd_IO连接到电源,将CS连接到Vdd以启用I2C。

Yes, you can. The STEVAL-MKI142V1 is just a adapter board, you can check the schematic

.
Don't forget to connect Vdd and Vdd_IO to power supply and the CS to Vdd to enable I2C.
