这是用c编写的一个minigui界面程序，对minigui的初学者有很大的参考价值-C This is used to prepare a minigui interface procedures minigui beginner has a lot of reference value

atmel的at91sam9260芯片的外部中断初始化实例以及一些常用接口初始化程序，源于实际应用-atmel chip of at91sam9260 external interrupt as well as some commonly used to initialize an instance of interface initialization procedure, from the practical application of

4位可逆计数器：将50MHz的时钟进行 分频后的结果作为时钟控制，根据输入进行条件判断，再通过设置一个四位的向量将结果输出，利用数码管显示在实验板上-CNTR 4: will be conducted at 50MHz clock frequency as the clock after the control conditions to determine the basis of inputs, and then set up a four through the results of the vector output, digital display board in the experiment

签名鉴别和笔记鉴别。In this paper, the local features obtained from the signature has been used to create the texture image based on the  spatio-temporal correlation matrix. The Gabor wavelets exhibit  desirable characteristics of spatial locality and orientation selectivity, and are optimally localized in the space and frequency  domains. So it has been chosen to extract the Gabor features of  the image. Signature is a small sample point problem and Support vector machine (SVM) is especially fit for two classes’ problem of small sample. The Gabor features vector has been imported to the SVM classifier and the classification result is obtained. The methods proposed in this paper are validated on the  S

这是adc0804与8051单片机接口的简单代码

改c程序基于stm32，开发环境是keil4.7，利用stm32的高级定时器TM1产生4路两两互补的SPWM波，分别去驱动H桥的四个桥臂，死区可通过程序自行设定，改程序利用查表法，一个正弦周期采样256个点，输出8位精度的spwm波。自带稳压程序，离散pid。输出波形较好。
