STM32 单片机产生32768Hz的方波 其中有定时器的配置

这是一个51单片机与PC的通信系统：利用3*4小键盘输入0~9的一串数字（不大于5），通过8051自带的串口发送给PC并显示在系统的6位LED上；单片机接收上位机的输入并显示在LED上。8051串行口经232电平转换后，与PC机串行口相连。PC机使用串口调试应用程序V2.2.exe，实现上位机与下位机的通讯。-This is a 51 microcontroller and PC communication system : use 3* 4 0 small keyboard input of a bunch of nine-figure (no more than 5), by 8051, bringing their serial sent to the PC and display system in the six LED; SCM receiving PC input and displayed on the LED on. 8,051 by 232 serial port-level conversion, and the PC serial port connected. PC using serial debugging applications V2.2.exe achieve PC and the next crew communications.

这是一个pid 程序，完成PID的计算和控制过程-This is a process pid to complete the calculation and control process PID

单片机键盘阵列扫描源程序解析，让你更好的理解按键扫描的原理-Single-chip arrays to scan the source code to resolve the keyboard, allows you to better understand the key principle of scanning

单片机C51串口中断接收和发送测试例程可以用来测试51单片机的中断接收 //和查询发送，另外我觉得发送没有必要用中断，因为程序的开销是一样的 -80C51 Serial interrupted receive and send test routines can be used to test 51 MCU interrupt reception// Send inquiries and, I also think that this is not necessary for discontinued because the process is the same as the overhead

这个UV3是正式版. 不像网上传的那样,在98下运行就出错. 这个版本是:3.03 是从DKARMV12A中拷出来的. 我一直都在用,好用着.-Lithography is the official version. Unlike Internet-in the case of 98 mistakes on the run. This version is : 3.03 from DKARMV12A which beat out. I have been in use and ease of use with.
