This is a simple program to calculate the output of artificial neural network (ANN) using microcontroller ATMega 32. Assume that the neural architecture is : 2 hidden layers with 4 and 2 neurons respectively and 1 layer output with 1 neuron.This program explains the step how to compute the ANN in off-line mode.Means the weights and biases are already exist (microcontroller is not doing the learning steps). These parameters are produced using MATLAB. Therefore, we have already made the appropriate architecture using MATLAB. The tansig function is use in both of hidden layer. Finally, the neural output will be displayed on LCD port C.

这个程序可以实现两个单片机之间双向通信的功能。(This program can realize the function of two-way communication between two microcontrollers.)

基于LMS的双向回波削除源码，不过回波幅度不要大于0.2,否则算法认为DOUBLE TALK DETECT。各位可修改此阀值，试试效果(based on the two-way LMS Echo slashing source, but not greater than the rate Echo 0.2, or that the algorithm** DOUBLE TALK. You can modify this threshold, try Effect)

说明：  单片机模糊控制pid源码，有需要的可以下载看看，可以用于大家参考学习，一起进步(SCM fuzzy control pid source code, there is a need to download can see, can be used for everyone to learn reference, progress together)

说明：  说明： 压缩BMP图片，图片质量有些损失，但压缩率很大(Explanation: Compressing BMP pictures may cause some loss of image quality, but the compression rate is very high.)
