STM32的固件库和DSP库，有应用例子，方便编程-STM32 DSP library firmware library and have applied examples, easy programming

基于stm32的DSP库的中ＦＩＲ滤波器功能的实现，滤波参数需要自己根据需要用Matlab计算，使用V3.0的固件库，属于基本stm32外设测试-Stm32 based DSP library function of the FIR filter implementation, the filter parameters needed in Matlab needs its own terms, using the V3.0 firmware, peripheral part of the ba
