摘要
本文介绍了单片机在声级计中应用的硬件和软件设计,着重叙述了便携式声级计本身的特点,如自动量程控制电路、最低功耗电路和64K RAM及软件逻辑开关电路等。这些电路对于便携式的数据采集系统有一定的参考价值。
This paper introduces the hardware and software design of a single-chipcomputer which is used in a portable sound level meter. The focal point of the paper is re-lated to the characteristics of the meter, such as, the automatic control circuit, thelowest-power-consumption circuit, a 64K RAM and a programming logical switch circuitand so on. These circuits have great applied value for a data collection system.
