LE05的Uart如果想配置为5M波特率的话，需要更大外部时钟或者双边沿采样。<img src="https://yt-static-main.oss-cn-shanghai.aliyuncs.com/nodebb/1386/a228579d-045c-4f4d-a2c1-db2aea1bb394.png" alt="c9564750-c769-472d-91a8-4acd0d908f72-image.png" class=" img-fluid img-markdown" /><br />
对于这个有个疑问：更建议双边沿采样还是增大外部时钟？双边沿采样会影响什么功能或者功耗吗？为什么OSR&gt;8之后没有双边沿了，双边沿是也有效吗？</p>
