i2c总线程序
- 本程序是i2c总线读写一个字节的程序。在写过程序中,不一定非要检测i2c的应答位,可以直接延时过去就行,但是在读过程中必须给应答信号,读完发停止位,一定确认所发的信号都发上了。否则在连续地址读的过程中可能不会出错,但是在随机度过程中就会出错,我的程序就是在给停止信号时没有给上,24cxx一直在输出数据,结果读出错。找着问题后我的程序只加入了一条命令便完全正常。-i2c bus read and write a byte procedures. The written procedure, no

dtmf
- 本程序用于检测音频文件中是否具有DTMF信号,若有则将其检出。 程序首先使用Goertzel算法求出以FRAMESIZE(默认200)为大小的一帧数据在8个DTMF频点上的能量。 对Goertzel算法的改进,对于系数的计算不是采用2*cos[2*pi*k/N],而是采用2*cos[2*pi*fn/fs],这样能够降低误差。 确定了8个频点的能量后运用一系列判决门限来确定有没有DTMF信号,以及信号是什么。 -This procedure used to detect wh
