说明：  51单片机用1602液晶显示串口接收到的数据(51 1602 MCU with LCD serial data received)

这是关于电路板的设计图，方便大家下载。呵呵 (This is about the second Five-Year Plan, said a key project for the future development of a box of reference )

本程序是虚拟示波器，可以显示多条曲线波形，调节幅值和时间(Oscilloscope can display multiple curve )

① 设计进程控制块PCB表结构，分别适用于优先数调度算法和循环轮转调度算法。 ②建立进程就绪队列。对两种不同算法编制入队子程序。 ③编制两种进程调度算法：1）优先数调度；2）循环轮转调度 (① design process control block PCB table structure, respectively, for priority scheduling algorithm and round-robin scheduling algorithm. ② establish a process ready queue. Two different algorithms for the preparation of subroutine into the team. ③ preparing two kinds of process scheduling algorithm: 1) priority scheduling 2) round-robin scheduling)

一个数字类型可提高开关电源的设计与实现，可以是很好的借鉴，但是要用特殊软件打开，把文件后缀复制到百度就可以找到(A digital type can increase the switching power supply design and implementation, can be a good reference, but use special software to open, copy the file suffix can be found on Baidu)

在stc51单片机上，timer0、timer1、timer2的控制(In the stc51 microcontroller, timer0, Timer1, timer2 control)

利用定时器产生PWM，使LED灯由亮到灭，由灭到亮逐步变化( Use timer produce PWM, make the light to destroy LED lamp, the gradual change to light out )

STM32单片机freemodbus的移植，主从机的都有(1, transplant FreeModbus1.5 and RT-Thread1.1.1 to STM322, development platform supports Eclipse, Keil, IAR3, can be used in the Eclipse plug-in version management EGIT 4, support Modbus RTU (ASCII untested))

MCU图片解码，使用STM32对JPEG图片解码，(STM32 JPEG decoder code,)
