STM32F429串口波特率最高支持多少


6楼
问题已经解决:
库函数里有这样一句描述: In order to reach higher communication baudrates, it is possible to enable the oversampling by 8 mode using the function USART_OverSampling8Cmd(). This function should be called after enabling the USART clock (RCC_APBxPeriphClockCmd()) and before calling the function USART_Init().
8倍过采样的使能函数我也调用过,可惜放错了位置,我放在了串口初始化之后,看来还是得好好研读官方给的文档啊
