利用STC15单片机实现对称PWM输出，可设置频率、占空比，利用JLX12863显示。( symmetrical PWM output based on STC15 MCU， frequency　and duty cycle can be setted, use JLX12863 display.)

说明：  通过单片机来控制水的温度。 通过设定预定温度，让单片机来自动调动开关，控制水温。(Through the single-chip microcomputer to control the temperature of the water. By setting the target temperature, so that the mobilization of single-chip automatically switches to control the water temperature.)

AT89C51控制步进电机，实现正反转加减速，驱动芯片是ULN2803.(AT89C51 control the stepper motor to achieve reversing acceleration and deceleration, the driver chip is the ULN2803.)

蓝牙4.0 天气温度湿度监测传感器, 使用用IT CC2540 或CIT CC2541 芯片实现.(Bluetooth V4.0 weather sensor and use IT CC2540/41 CPU to monitor remote temperature.)

一个LED灯带的程序，通过红外遥控器进行遥控，实现变色，七彩跳变等功能(LED lights with a procedure carried out by remote control infrared remote control to achieve color, colorful hopping function)

TM8211演示程序 单片机 STC12C5A32AD 晶振 33MHZ 一分频速度快T=1/33=30ns(TM8211 demo program microcontroller STC12C5A32AD Crystal 33MHZ one-way speed T = 1/33 = 30ns)

基于瑞萨单片机，R8C/25的UART通讯程序，针对KEYPAD上位机开发的通讯程序，包含校对。(R8C/25 UART0)

AGV的路径选择，寻径代码等……吹水凑数从现在开始(Roadmap choosing, just part of the whole code.)

这个源码是利用STM32操作ATT7022E，并简单的读取各项基本参数的通讯例子。STM32使用R8T6，计量芯片是ATT7022E。例程中采用模拟SPI来对ATT7022E进行操作，里面的初始化、校表的寄存器操作均是根据ATT7022E的用户手册和应用笔记的最新寄存器操作进行。希望这个例子能对使用这款芯片做电力仪表的带来帮助。(This source is the use STM32 operating ATT7022E, and a simple example of the basic reading communication parameters. STM32 using R8T6, metering chip is ATT7022E. Analog SPI routines to manipulate ATT7022E, register operations inside the initialization, school tables are made in accordance ATT7022E user manuals and application notes for the latest register. I hope this example will bring help to use the chip to make electricity meters.)

基于51单片机设计的万年历，采用LCD1602实现时间的显示（年月日时分秒）时间以及闹钟的设置(Based on the calendar designed by 51 single chip computer, LCD1602 is used to realize the display of time (year, month, day, hour, second) and the setting of alarm clock.)
