软件流控制(Software flow control)是在计算机数据链路中的一种流控制方法,特别适用于 RS-232串口通信;它是采用特殊字符来传输带内信令,特殊编码字符称作XOFF与XON(分别表示 “transmit off” 与“transmit on”)。因此,也被称作 “XON /XOFF流控制”; 使用ASCII字符集,XOFF一般为字节值 19(十进制),XON为字节值...
UART hardware is configured as DTE device: theRTS(Request-to-Send) signal as anoutput theCTS(Clear-to-Send) signal is aninput 2. one transimit The active-lowRTS andCTS signals work together to control transmission flow. Hardware flow is typicallycontrolled by the DTE device, which could be...
UART Flow controlNarendra Kulkarni29 Intellectual 590 points Other Parts Discussed in Thread: TM4C129XNCZAD Hello, (TM4C129XNCZAD based custom board talking to a TM4C129NCPDT over UART. TI-RTOS 2.14, CCS 6,1, TI-ARM compiler 5.25) We want to implement flow control for the UART ...
Hello! I am now working on a custom i.MX6Q board with Yocto(3.10.17_1.0.2),and I want to enable HW flow control for UART2(Which is used for BT
Pls try to enable uart receiver FIFO and set the FIFO threshold to a non-zero value, then check if the RTS signal change or not. If the RTS signal changes after you enable receiver FIFO, it means that the RTS signal is flow control signal. Pls have a try BR Xi...
Hi, We are using the XMC4700 with a couple of UART apps. One of the parts we are communicating with is a Bluetooth module that requires CTS and RTS

It is so annoying finding the questions in the forum but no real answer. I don't understand what the sw flow control does based on documentation. I also tried searching for examples of uart with DMA and always find only evasive answers like "surely you don't need it" I'm trying to ...
UART Flow Control is a method for slow and fast devices to communicate with each other over UART without the risk of losing data. Consider the case where two units are communicating over UART. A transmitter T is sending a long stream of bytes to a receiver R. R is a slower device than...
I think the TX pin configuration should be done automatically by the UART driver, so it is a bug. I can open a separate issue if you want. The RX pin configuration is non-standard and board-specific, therefore it is OK to do it manually. The hardware flow control option can be added...
