说明：  代码使用C编写，平台为Cortex-M3 系列STM32F107VCT开发板。 用于将ARM ADC通道获取的5s 400Hz双通道信号，共2000*2个， 通过卡尔曼滤波，提取主成分，8组（共16个）个特征，最后将此信号分类成4种。 此源码为其中核心部分，VC测试通过。（不含信号文件和基础源文件）

ARM ADC channel for 5s 400Hz dual-channel signal, a total of 2000* 2, by Kalman filter to extract the main ingredient, 8 (16) characteristics, and finally this signal is classified into four kinds.
