Hi,

We have no ready-made non-standard baud rate scheme. However, according to the description in the chapter UART in the reference manual, the baud rate depends on the module clock, and the module clock comes from UART_CLK_ROOT. At the same time, the maximum UART_CLK_ROOT clock does not exceed 80MHz, and the default value is 4MHz. The relationship between module clock and band rate is that module clock is greater than or equal to band rate X 16.

According to above description, non-standard band rate should be no problem.


So you can try.

<没有现成的方案,您只能根据上面的描述,代码里去调试一下>

Have a nice day!
