利用单片机MSP430f149单片机实现的 实验八 ADC与LCD(The use of single-chip MCU MSP430f149 experiment eight ADC and LCD)

本代码是基于检测遥控飞机手柄输出的PWM信号频率，转换为角度信息，再作为步进电机移动输入量，最终实现使用遥控飞机手柄摇杆精确控制步进电机转动角度的目的，包含PWM频率检测模块和步进电机驱动模块等。(This code is PWM frequency signal detection based on the output of the remote control aircraft converted to handle, angle information, and then as the stepper motor movement input, and ultimately use the remote control aircraft joystick handle precise control of stepper motor rotation angle, including PWM frequency detection module and stepper motor drive module.)

给大家介绍一个PDF操作的sdk。通过这个sdk你可以直接对PDF文件进行显示、修改、新建及打印(Debenu Quick PDF Library Guide)

说明：  avr单片机GCC程序设计说明书~~大家都来下载吧，有利于avr单片机的学习。。。(avr microcontroller GCC program design specifications ~ ~ we are all to download it, avr microcontroller is conducive to learning. . .)

说明：  Arduino 对接收到的信号进行解码操作，从而得到按键信息，根据按键值控制舵机。(By decoding the received signal, the key information is obtained and the steering gear is controlled according to the key value.)

在过程控制中，按偏差的比例（P）、积分（I）和微分（D）进行控制的PID控制器（亦称PID调节器）是应用最为广泛的一种自动控制器。它具有原理简单，易于实现，适用面广，控制参数相互独立，参数的选定比较简单等优点；而且在理论上可以证明，对于过程控制的典型对象──“一阶滞后+纯滞后”与“二阶滞后+纯滞后”的控制对象，PID控制器是一种最优控制。PID调节规律是连续系统动态品质校正的一种有效方法，它的参数整定方式简便，结构改变灵活（PI、PD、…）(In process control, the PID controller (also called PID regulator) controlled by deviation ratio (P), integral (I) and differential (D) is one of the most widely used automatic controllers. It has the advantages of simple principle, easy realization, wide application, independent control parameters, simple parameter selection, etc. It can also be proved theoretically that PID controller is an optimal control for the typical object of process control - "first-order lag + pure lag" and "second-order lag + pure lag". System. The regulation rule of PID is an effective method for dynamic quality correction of continuous system. Its parameter setting method is simple and its structure is flexible (PI, PD,...).)
