你好,我正准备使用S32K116的SPI,我需要两个需要FLEXIO来帮助我,但是我发现FLEXIO模拟的SPI的波特率设置好像有问题,导致我的设备通讯一直出问题。有什么可以帮我的方法好吗? 波特率配置成 10K 或 100K 设备会出现问题,导致工作不能往下进行。希望得到帮助谢谢。

Hi,

The bitrate can be set in the FlexIO_SPI driver:

But it depends on the FlexIO clock source too.

How did you set the drivers and what bitrate do you measure on the bus?

 

Thank you,

BR, Daniel
