一般,系统机均有声响及音乐输出装置,并配有相应的语句,但是,常见的单板机却没有这个功能。本文以TP801单板机为例,介绍单板机实现这一功能的原理,附加电路及其汇编程序。一、原理及附加电路单板机大都有录音机接口电路,利用这一电路和相应的程序,可以将RAM中的易失信息转储到盒式录音磁带上,这一过程本身就是音频输出的过程。它
In general, the system machine has a sound and music output device, and with the corresponding statement, but the common single board machine does not have this feature. In this paper, TP801 single-board machine, for example, introduce the principle of single-board machine to achieve this function, additional circuits and assembly procedures. First, the principle and additional circuit Slot machine most of the tape recorder interface circuit, the use of this circuit and the corresponding program, the volatile information in RAM can be dumped to the cassette tape, the process itself is the audio output process . it
