MT8880是DTMF信号的解码芯片，在智能电话控制中使用很多，这个里面有单独的拨号与振铃检测摘机的程序，每个程序都有详细的注释，非常好用-MT8880 is a DTMF signal decoder chip in the smart phone to use a lot of control, the inside has a separate dial-up hook and ring detection process, each program had detailed notes

Win32 Kernel Rootkits modify the behaviour of the system by Kernel Native API hooking. This technique is typically implemented by modifying the ServiceTable entries in the Service Descr iptor Table (SDT). Such modification ensures that a replacement

在调试过程中多处使用串行口返回信息（由于没有源码级仿真器）； 在空闲任务中的HOOK函数打印输出串口信息，并且闪烁LED； 在各个任务中打印输出串口信息，并且闪烁单个LED； 对于Os_cpu_a核心部分TimeTick函数另作详细说明；-Many places in the process of debugging using the serial port to return the information (the absence of source-level simu
