本文档提供了用C语言写的单片机滤波算法，因为单片机尽管不擅长实现算法和进行复杂的运算，但在一些特定的场合，如实时动态测量等应用上还是要实现一定的滤波算法。-This document provides the use of C language written in single-chip filtering algorithm, because the realization of single-chip, while not good at algorithms and complex calculations, but in some specific occasions, such as real-time dynamic measurement applications or to achieve a certain degree of filtering algorithm.
