CVI串口调试总结RS232 对于CVI串口调试助手（rs232）1 软件简单介绍 1.1 串口界面 串口调试助手用来与下位机连接，与下位机进行数据交换，实现PC机与单片机的连接和实时数据采集。实现了十六进制的数据接收，如图1-1。图1.1 数据转化为16进制
The receiver looks for a "1" stop bit at the end of the frame. A framing error is reported when that stop bit doesn't come when the receiver expects it. The problem could be that the transmitter and receiver aren't set for the same speed, number of data bits, or whether or not t...

起始位- 在RS-232中,我们发送的第一件东西叫做起始位。这个起始位(是Kleinschmidt在一战期间发明的)是在我们发送的每个字符之前添加的一个同步位。这被认为是一个空格或负电压或0。 stop bit- The last thing we send is called a stop bit. This stop bit tells us that the last character was just sent...

Unfortunately, Microsoft is so "clever" as to take 11 bit from the UART, use the 3 status bits - parity, framing error and break - to fire events and then throws these 3 bits away before the result is stored in a 16-bit stream, which could easily have contained all 11 bits. The ...
