Description: 有限状态机FSM思想广泛应用于硬件控制电路设计，也是软件上常用的一种处理方法(软件上称为FMM--有限消息机)。它把复杂的控制逻辑分解成有限个稳定状态，在每个状态上判断事件，变连续处理为离散数字处理，符合计算机的工作特点。同时，因为有限状态机具有有限个状态，所以可以在实际的工程上实现。但这并不意味着其只能进行有限次的处理，相反，有限状态机是闭环系统，有限无穷，可以用有限的状态，处理无穷的事务。-FSM thinking widely used hardware control circuit design, the software is commonly used on one method (FMM called on the software -- limited information machines). Its complex control logic is decomposed into a finite number of stable state, in every state judgment on the incident, treated as continuous variable discrete digital processing, compliant work characteristics. Meanwhile, as the finite state machine with a finite number of the state, so it can be in the actual realization of projects. This does not mean that its only a limited time to deal with, on the contrary, finite state machine is the closed-loop system, limited infinite, you can use the limited state, handling endless affairs.

Description: dsp2812 的AD程序含有AD校正，有详细的注释，程序运行正确。2812 内部自带了 12 位，总共 16 路的 AD，这对于需要节省成本的项目来说是一件好事，AD 的价格一般都是比较贵的，2812 的内部 AD 既然能够满足我们的基本需求，也就可以不用另外设计 AD
电路了。但是，由于一些内部的原因，使得 2812 的 AD 精度达不到 12 位的精度，而且误差比较大，为了提高内部 AD 的精度，通常在硬件和软件的角度采用补偿措施对其进行校正，使得其精度能够有所提高，能够满足大多数的应用场合。 -The AD dsp2812 programs contain AD correction, have detailed notes, and the program ran right. 2812 internal take 12, 16 total road, this to the AD for projects that need to save cost is a good thing, AD prices are generally more expensive, 2812 internal AD since can meet the basic needs, we also can need not another AD circuit design. But, since some of the internal reasons, make 2812 AD precision of less than 12 a precision, and the error is bigger, in order to improve the precision of the internal AD, usually in the hardware and the software of the Angle of the compensatory measure calibration, making its accuracy, and can meet to improve most applications.
