Hi NXP team, When I used S32K312 serial port DMAto send data sometimes the data is normal and sometimes the data isall 0; Sometimes the data is
com=newSerialPort("COM5");//实例化SerialPort并设置COM口com.BaudRate =115200;//波特率com.Parity = Parity.None;//无奇偶校验位com.StopBits = StopBits.Two;//两个停止位com.Handshake = Handshake.RequestToSend;//控制协议com.ReceivedBytesThreshold =13;//设置 DataReceived 事件发生前内部输入缓冲区...
I am interfacing an led with via serial port. I have set up the serial port already. I have a display with these specification parameters: baudrate:2400 data:8 bits end code:1bit I am trying to display the test code which comes in the following format: ...
获取或设置 SerialPort 输入缓冲区的大小 ReadTimeout 获取或设置读取操作未完成时发生超时之前的毫秒数 ReceivedBytesThreshold 获取或设置 DataReceived 事件发生前内部输入缓冲区中的字节数 RtsEnable 获取或设置一个值,该值指示在串行通信中是否启用请求发送 (RTS) 信号 ...

The serial port on the BB-400 port is /dev/ttySC0. This is basically the same as a COM port in windows. You can reference this in your application if you wish
SerialPort.DataReceived之“管收不管埋” 通过把SerialPort进行封装,以多线程和缓存的方式处理串口的发送和接收动作。 一、现象 不管如何设置ReceivedBytesThreshold的值,DataReceived接收到的数据都是比较混乱,不是一个完整的应答数据。 二、原因 1、上位机下发的命令比较密集,以200ms周期发送实时状态轮询命令。
