用c语言编写串口程序 在当今,流行的编程软件种类繁多,它们编程方便、易于维护,但是在与硬 件直接打交道和编制系统软件时却束手无策,于是C语言就有了用武之地。C语言 作为汇编语言与高级语言之间的一种过渡语言,兼有汇编语言的高效和高级语言 的方便。   在通讯中,为了保证行运安全可靠,标准的串行口必须具有许多握手信号和 状态信息。这是因为通讯的各个计算机CPU速度不一样(这会导致“错帧”)以 及发送机发送数据速度比接收机接收速度快(这会导致“过冲”)。为解决这个 问题,我们采用一个简单的握手信号,即发送机每次仅发送半个字节(低4位) 的数据,而另外半个字节(高4位)则用来传送信息。我们可以对信息位(高4位) 进行如下简单的编码: 0H:发送的是新的半个字节数据 1H:重新发送上次传送错误的数据 2H:文件名结束 3H:文件结束 这样,每当发送机发送一个字节以后,就等待接受机发回送信号,这回送信号就 是发送机发送过来的那个字节。发送机接收到回送信号后,把它与刚发送的字节 相比较,如果相同,就发送新的半个字节,否则就重新发送。新数据与旧数据通 过信息位来区分。下面就是用C语言编写控制串行口的程序。 -Serial procedures in the preparation of today's popular programming software, and a large variety of their programming and easy to maintain, but to deal directly with the hardware and system software when compiled a loss, so there will be a C language battlefield. C language as the compilation and Advanced Language a transition between languages, both assembly language and the efficient high-level language convenience. In telecommunications, in order to ensure safe and reliable transport firms, the standard serial I must have shook hands with many signals and state information. This is because the various computer communications CPU speed is not the same (this would lead to "the wrong frame") and transmitter to send data faster than fast receiver to receive (this would lead t

On power up, the firmware starts executing code at address 0h. After some housekeeping tasks it will determine whether it is attached to a USB or a PS2 interface. From that, it will branch either to USB_Main or PS2_Main. -On power up, the firmware starts executing code at address 0 h.

FAT文件系统原理 计算机在按下power键以后,开始执行主板bios程序。进行完一系列检测和配置以后。开始按bios中设定的系统引导顺序引导系统。假定现在是硬盘。Bios执行完自己的程序后如何把执行权交给硬盘呢。交给硬盘后又执行存储在哪里的程序呢。其实,称为mbr的一段代码起着举足轻重的作用。MBR(master boot record),即主引导记录,有时也称主引导扇区。位于整个硬盘的0柱面0磁头1扇区(可以看作是硬盘的第一个扇区),bios在执行自己固有的程序以后就会jump到mbr中的第一条指令。将系统的控制权交由mbr来执行。在总共512byte的主引导记录中,MBR的引导程序占了其中的前446个字节(偏移0H~偏移1BDH),随后的64个字节(偏移1BEH~偏移1FDH)为DPT(Disk PartitionTable,硬盘分区表),最后的两个字节“55 AA”(偏移1FEH~偏移1FFH)是分区有效结束标志。-FAT file system in principle computer keys after pressing the power to start procedures for the implementation of motherboard bios.
