单片机的串行口测试程序

这是单片机C语言位操作函数！给大家参考使用，可以直接在单片机中引用，不需要自己去编写，弥补了C语言位操作没有汇编灵活的缺点-This is the C language SCM- manipulation functions. For your reference use, can be directly invoked in SCM, you do not need to do to prepare. compensate for the C-language compilation flexible operation without the shortcomings

这是一个单片机与MFRC522通信的程序，采用C语言编写。-This is a single-chip microcomputer with MFRC522 communications procedures, the use of C language.

基于80C51单片机源码公开的操作系统1.20.2 版RTOSsmall_rtos1.20.2-80C51 microcontroller based on the open-source operating system version 1.20.2 RTOSsmall_rtos1.20.2

AP89042是不可从复录音的分段式语音芯片,对语音电路的开发人员有一定的帮助.-AP89042 is not from the sub-Minute recording voice chip, the voice circuits developers will help.

这是一个为51系列单片机开发的4*4键盘驱动程序。该驱动程序包括2个文件，使用时将C文件关联入工程，在调用文件前包含H文件即可。本键盘驱动程序具有两个接口函数提供两种扫描方式（阻塞和非阻塞），可以任意定制返回键值，具有防抖动处理，具体使用方法可以参见注释。（本程序在Keil C51开发环境中测试成功，并经过多次实践应用）。-This is a series of 51 MCU development of the 4* 4 keyboard driver. The drive included two documents, the use of paper will be linked into C, the call of documents containing H documents. The keyboard driver has two interface functions provide two scan mode (blocking and non-blocking), it will return to arbitrary custom keys with innovative and handling, the use of specific methods can be found in Notes. (This procedure Keil C51 development environment to test successful, and after several practice application).
