921600波特率的情况下,发现传输频繁出错,查找log发现,出错时串口出现UART_BREAK中断... 坑了2天,尝试了各种解决方法 最终使用版本回退发现某一版本打开了power management功能之后,导致串口接收数据不全。 在menuconfig中关闭power management,一切正常。

DIN就是模块的串行输入口，接单片机的TXD，但“send a serial break”应该就是发送一个“break”信号吧...
A break signal is an invalid character. When the RS-232 line is idle, the voltage is in the 'mark' (or '1') state (which is -12 volts if I remember right). When a character is sent, the protocol toggles the line to the 'space' (or '0') state for one bit time ...
It has a typedef for uart event types. One type is UART_BREAK. The .h file goes on to declare the write function with break, but no mention of reading. I have code that reads based on the break. (I didn't write it...) The data stream is 513 bytes after the break. But, I ...
1:break field generate:I found break condition in TM(A break condition is activated by setting the UART_LCR[6] BREAK_EN bit),but i do not know how to Control the length(13 bit low) of the break field 2:break field detection:UART_LSR_UART[4]RX_BI indica...
A bit of background. I have a project that is already debugged and worked fine on both ESP32-S2 and ESP32-WROVER. There was a long break from work on the project. After I got to work again, there were several updates to the esp-idf frame...
UART READ BYTES ERROR (IDFGH-1839)#4048 Closed What if you change this You should then get data event and break event As for the mod, the newer uart.c has changed so much I can't figure out where to put the mod now... uart.c at line 850 now is: ...
