What is the difference between I2C0 and I2C1 on FRDM-K64

Hello，

I use SDK_2.0_MK64FN1M0xxx12 the I2C routines for communication, but when I put the hosts set I2C1, the slave is set to I2C0, the two can not communicate properly, why? (SPI also have the same situation)

P.S：The code is downloaded from the NXP，and nothing modification.Accessory is the code for I2C and SPI

Look forward to answer.

各位好：

我使用SDK_2.0_MK64FN1M0xxx12中的I2C例程进行通信，但是当我把主机设为I2C1，从机设置为I2C0时，这两个没法正常通信，请问这是为什么？（SPI也有同样的情况）

附件是我从NXP下载下来的例程代码

期待各位的回复。

你好,

不知道你用的是哪个版本的FRDM-K64F的板子, 老版本的K64板子的I2C 信号线有错误. 具体信息可以参考errta:

您好，

谢谢您的回复，我在重新查看了程序和线路后，发现是I2C0和I2C1之间的连接线出现了问题，还是非常感谢您的回答。:smileyhappy:
