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...
I have an application that uses the UART_RTOS_Receive() and associated functions. Currently this is implemented in MCUXpresso with FreeRTOS. But now I would like to implement hardware flow control using RTS/CTS. Is there an API that supports this? If not what would be the...
I understood that this UART task should be performed uninterrupted. For this, I tried running file writing tasks separately using xSemaphoreCreateMutex() but still the data is missing. Now I'm trying to use software flow control by sending XON and XOFF values. But still, the data is ...
Poster Dave has well defined/detailed. Assuming that you've "mastered" the "non" Flow Control aspect of Uart operation - it should be relatively simple to employ either a spare MCU GPIO pin (configured properly to "drive" or receive the MCU's standard flow control pins) or a simple dip ...

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
This causes potential for blocking functionality and has lead to buffer overflows on the UART. Flow control helps but not all UARTs have flow control and I was asked if that flow control could be done low level in Micropython. That sounded like an interesting enough idea to bring up here....
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 ...
