利用MSP430单片机实现5分钟倒计时。用Timer_A实现1s定时，4位共阳型数码管显示时间，显示格式为：“x-xx”，分别代表“分”、“十秒”和“秒”。每隔1s，倒计时器的时间减1，倒计时从4分59秒开始计时，至0分0秒结束，停止计时。(MSP430 microcontroller is used to realize 5 minute countdown. Timer_A is used to realize 1s timing and 4-bit common-sun digital tube display time. The display format is "x-x x", representing "minutes", "ten seconds" and "seconds" respectively. Every 1s, the countdown time is reduced by 1. The countdown time starts at 4:59 seconds and ends at 0:0 seconds.)

ATMEG128单片机开发板上自带的LED点阵源程序，给大家分享一下(ATMEG128 microcontroller development board comes with the LED dot matrix source, to share with you)

内含服务端和客户端，服务端开启后，客户端可以与另外一个客户端进行语音录音，也可以进行广播，类似网络会议(暂不支持视频).适合想了解多媒体编程和网络编程的初学者.(Includes server and client,when server opened, the client can chat with another client also record voice, you can also broadcast to all client online, similar to the network meeting (not support video). Suited to people who want to know multi-media programming and network programming.)

图象增强小波变换将一幅图象分解为大小、位置与方向都不同的分量。在做逆变换之前能改变小波变换域中某些系数的大小，，这样就能够洋选择的放大所感兴趣的分量而减小不需要的分量。给定一个图象信号，用二维小波分析析对图象进行增强处理。 (Image enhancement wavelet transform decomposition size, location and direction of the different components of an image. Wavelet transform domain, some the size of the coefficient can change before doing the inverse transformation, so can the component of interest to the amplification of the ocean choose to reduce the unwanted weight. Given an image signal, the analysis of two-dimensional wavelet analysis of image enhancement processing.)
