LED

硬件电路比较简单，3个LED指示灯，5个按键控制上下左右及暂停，LCD显示。总共有20关。设计用到了逻辑门控制电路。(The hardware circuit is simple, 3 LED lights, 5 key control above and below and suspension, LCD display. A total of 20 customs. The design used in the logic gate control circuit. )

根据对应的按键值，对应输出相应的电容值，并做掉电检测(According to the corresponding key value, corresponding to the output of the corresponding capacitance values ​ ​ and do brownout detection)

这是一份关于MSP430的C程序和课件，虽然不是很全面，但是对于新手还是够用的。(This is a report on the MSP430 C program and courseware, though not very comprehensive, but still enough for the novice.)

tms320F28335是一款新的dsp芯片，svpwm算法的实现和以前的2812等有点不同，现在将我写的分享给大家，已经调试过了，晶振是20MHz。28335的svpwm的实现。(tms320F28335 is a new dsp chip, svpwm algorithm implementation and the previous 2812 and so a little bit different, now I write for everyone to share, debugging, and the crystal is 20MHz. 28335 svpwm implementation.)

步进电机是将电脉冲信号转变为角位移或线位移的开环控制电机，是现代数字程序控制系统中的主要执行元件，应用极为广泛。。在非超载的情况下，电机的转速、停止的位置只取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，当步进驱动器接收到一个脉冲信号，它就驱动步进电机按设定的方向转动一个固定的角度，称为“步距角”，它的旋转是以固定的角度一步一步运行的。可以通过控制脉冲个数来控制角位移量，从而达到准确定位的目的；同时可以通过控制脉冲频率来控制电机转动的速度和加速度，从而达到调速的目的。(Stepper motor is an open loop control motor which transforms electrical pulse signal into angular displacement or linear displacement. It is the main executive element in modern digital control system, and is widely applied. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle, called "step", it is the rotation of the fixed point of the operation step by step. We can control the angular displacement by controlling the number of pulses, so as to achieve the goal of accurate positioning. At the same time, we can control the speed and acceleration of motor rotation by controlling the pulse frequency, so as to achieve the purpose of speed regulation.)
