检测电路输出电压变化量，控制电压变化量在规定的变化区域内变化。且让MSP430F149单片机的IO口输出由小逐渐增大的信号作为电流参考信号，输入到比较器的同相输入端。(The change in output voltage detection circuit, the control voltage changes the amount of the required changes within the region. Let MSP430F149 microcontroller IO port output signal from the small increases as the current reference signal input to the comparator s inverting input.)

单片机程序设计100例，基于51的设计，初学者的好帮手，我的入门导师啊。呵呵呵呵！(100 cases of SCM process design, based on 51 design, a good helper for beginners, I started mentor ah. Oh Oh!)

说明：  采用stm32f4核心板，实现AD采集，效果很理想，可测量流量，液位(Achieving Flow Acquisition)

NXP lpc1114 ADC测温程序,最小系统开发。测试通过。(NXP lpc1114 ADC measurement procedures, minimum system development. Test.)

输入一个数字，数码管可倒计时显示数字，显示到0后又重新显示(Enter a number, digital countdown display digital display to 0 and then redisplay)

由单片机8951来控制 c语言编写 具有实现正转反转 加速减速 采用PWM调制的方法(By the single-chip microcomputer to control the 8951 with c language implementation is to accelerate the slowdown in the use of inverted PWM modulation method)

SIM800C资料，包括原理图，STM32的例程(SIM800C data, including schematic diagrams, STM32 routines)

Proteus8.2仿真TX-1C51单片机开发板，例9.1MAX7219控制8X8点阵(Proteus8.2 simulation TX-1C 51 microcontroller development board, Exam 9.1 MAX7219 8X8 dot matrix)
