ATMEGA16单片机的IIC总线测试程序。-ATMEGA16 MCU IIC bus test program.

利用AVR单片机设计IIR 低通滤波器，其中截止频率、抽样频率都有说明，运行环境是先用IICAVR建立工程，再将该代码加入进去即可-Use AVR microcontroller IIR low-pass filter, which cut-off frequency, sampling frequency with specifications, running environment is to use IICAVR build project, then the code can join
