1602vD

两个12V的电机驱动履带式底盘完成到制定目标运动的任务，可以通过点触屏进行无线控制。(Two 12V motor-driven crawler chassis complete the task of setting the target motion, which can be controlled by wireless touch screen.)

listctrl控件，用回调函数进行排序(listctrl controls, using a callback function Ranking)

PS2通信，用stm32单片机模拟键盘鼠标往电脑送数据。(PS2 communication with stm32 SCM simulation to send data to a computer keyboard and mouse.)

按键判断 进行行扫描m表示对应的行数 n表示对应的列数 对应数值亮(Judgment keystroke scan lines express the corresponding m number of rows n that corresponds to the number of rows corresponding numerical Liang)

设计的电机驱动控制系统的主要功能有①控制电机的正转、反转；②为电机设计控制速度，有5m/s、10m/s、15m/s三个等级；③给电机设定转动的位移，让电机按照设定的位移移动；④1602液晶上显示电机的位移和速度；⑤利用4*4键盘数字输入控制电机的速度、按键C和D控制正反转、按键B控制三个档位的速度。(Using SCM software and hardware systems to achieve precision stage displacement, velocity through three or four phase stepper motors (motors meet the acceleration and deceleration characteristics), control the direction, location. Completion of the control circuit board hardware, including CPU, power amplifier, buttons, LED display. Software can be implemented in C.)

基于430的DC_DC变化，采用PID控制，调节PWM的输出占公比，从而反馈调节输出电压(Based on 430 DC_DC change, using PID control, adjust the PWM output accounted common ratio, thus regulating the output voltage feedback)

这是有关pwm的控制，可以控制它周期的长短来控制灯的亮度，还可以控制它自动调光。(This is the control of the pwm, the length of the cycle it can be controlled to control the brightness of the lights can also control the automatic dimming.)

It was a ATmega128 Sleep mode and awake mode programed by avr studio4

使用FFMPEG库进行视频解码，然后在一个Static控件上使用SDL2.0进行视频显示，相比SDL1.0,2.0版本支持多窗口同时显示，性能也大幅提升。（demo中未处理音频帧）。本Demo优点：将视频解码和显示分别封装了两个类CFfmpegDecod和CSdlShow，便于学习和理解播放流程。适合学习者使用。(Using the FFMPEG library for video decoding, and then on a Static control on the use of SDL2.0 video display, compared to the SDL1.0,2.0 version supports multi window at the same time, performance is also greatly improved. (demo is not processed for audio frames). The Demo advantages: the video decoding and display are encapsulated in two classes CFfmpegDecod and CSdlShow, easy to learn and understand the playback process. Suitable for learners to use.)
