kl17系列MKL17Z128VFM4芯片uart0串口输出是乱码

乐嘉思密达

我是直接使用KSDK中的demo进行设置，gpio控制和OSA_TimeDelay()函数都能正常使用，唯独这个串口的功能我调试了2天了也一直是乱码。

我知道答案 目前已有3人回答

我是直接用KSDK_Project_Generator_x64软件生成的工程配置如下：


使用的外部时钟如下：


串口的波特率、校验位、停止位等等设置的都没问题，但就是显示乱码，我唯一怀疑的问题就是时钟设置不对，但是OSA_TimeDelay()函数运行的很正常啊，难道是串口时钟设置异常么？

问题已解决，因为板子的串口输出是232而我一直接的是TTL
