2.3 如果你想不使用循环,可以采取一次性读取出来数据,这样就不会那么麻烦,仔细阅读它自己的接口,找到适合自己的接口,我把我的代码发给大家参考一下: private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e) { byte data = 0; int len = 0; intbufsize= (int)serialPort1.BytesToRe...
The advantage of asynchronous transmission, apart from its cheaper cost, is that data can be transmitted whenever convenient for the sender (unlike synchronous where all data are sent in one continuous stream). Consequently, the majority of serial transmissions are performed asynchronously. Sign in ...
回调函数port_DataReceived用于响应DataReceived事件,通常在这个函数里读取串口数据。它的第一个参数sender就是事件的发起者。上面的代码中,sender其实就是port。也就是说:多个串口对象可以共用一个回调函数,通过sender可以区分是哪个串口对象。 回调函数是被一个多线程调用的,它不在主线程内。所以,不要在这个回调函数里...
If the sender does not receive a correct response packet within a specified time period, the transmission times out, as shown in the following figure. MCUModuleSend the command NRespond to the command NMCUModule For more information, see Protocol list. The module sends control commands and the...
Hardware control: The Request-to-Send (RTS) line is set to false when the receiver's buffer is full. This indicates to the sender that it must stop sending data. When the buffer is able to hold data, the RTS line is set to true that indicates to the send that it is now ready to...
the invention relates to a process for the serial transmission of data series a transmitter (10) and a receiver (11), the data being expressed by means of a predefined words (21, 22, 23) of consecutive bits, each bit is located in a determined logic state of the two possible logic sta...
For example, if you wanted to create a Gcode Sender web app to enable people to send 3D print or milling commands from your site, this would be a perfect use case. Or if you've created an oscilloscope web app that connects to an Arduino, it would be another great use case. Finally ...
