用LPC213X系列的PWM來產生語音。語音數據來源于PC機轉換后得到的。最大可以是16位的。
由于是PWM所以輸出端口需要低通濾波才能夠得到比較干凈的聲音。
可以經過修改使用LPC2132以上的ARM的D/A來產生。
This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM.
This is an example how one could hide a process on Windows based
operation systems from task viewers like ProcDump (G-RoM, Lorian
& Stone) or ProcessExplorer (SysInternals).
It could e.g. be used as some kind of dump protection.
The way to get this done is very different on NT and 9x machines.
