目前串行通讯接口的标准有很多种,而且一定程度上都得到了发展,不过都是在RS-232C的基础上进行改进而成的。改进而形成的。目前已在微机通讯接口中被广泛采用,不仅已被内置于每台计算机,同时也已被内置于从微处理器到主机的多种类型的计算机及其相连设备。而串行与单片机的通讯技术可以解决多台下位机的多内容同时显示,还可以方便地完成多机通讯技术、多数据处理等优点。但是当同时用到两种通信方式时,很可能产生串行冲突或其他不可预料的错误,对开发工作极其不利。所以,此系统解决了这种开发中的问题,依靠软件仿真数据信号的发送、接收和多种通讯方式的测试。利用简单的硬件连接去检测串行和单片机通讯是否能正常工作。
There are many kinds of standards of the serial communication interface at present, have developed to some extent, but all are improved on the basis of RS-232C. Improved and formed. Has been widely used in computer communication interface, not only has been built into each computer, but also has been built from the microprocessor to the host of many types of computers and their connected devices. The serial and single-chip communication technology can solve more than one lower-bit machine while displaying multiple content, but also can easily complete the multi-machine communication technology, multi-data processing and other advantages. However, when both communication modes are used at the same time, serial conflicts or other unforeseen errors are likely to occur, which is extremely unfavorable to the development work. Therefore, the system solves this problem in development, relies on the software to simulate the sending and receiving of data signals and the testing of multiple communication methods. Use a simple hardware connection to detect serial and microcontroller communication is working properly.
