文中介绍一种不用光耦就可以实现隔离的方法

基于FPGA的PCM编码器与解码器的设计-about fpga and pcm

本文介绍一种以CPLD[1]为核心、以VHDL[2]为开发工具的时间控制器，该控制器不仅具有时间功能，而且具有定时器功能，能在00：00～23：59之间任意设定开启时间和关闭时间，其设置方便、灵活，广泛应用于路灯、广告灯箱、霓虹灯等处的定时控制。-This article describes a CPLD [1] as the core, VHDL [2] for the development of tools for time controller that features not only has the time, but with the timer function, can be between 00:00 ~ 23:59 arbitrarily set to open time and closing time, and its convenient, flexible, widely used in street lamps, advertising light boxes, neon lights, etc. The timing control.

数控直流稳压电源源程序 本设计由两个电路模块构成：直流稳压源电路（+15V,+5V,-15V），程控电路。并且巧妙得反置使用D/A变换器。使程控输出电压0-9.9手动可调，步距为0.2V。并可预置电压值，采用LED同步显示。-NC DC power source circuit of the design of two modules: the source DC circuit (+15 V,+5 V,-15V), program-controlled circuit. And clever use of a reversal of D/A converter. So that the output voltage programmed manually adjustable 0-9.9, step to 0.2V. And preset voltage value, shows that the use of LED synchronization.

本系统包括的功能主要有以下几点： （1）库存管理的各种信息的输入，包括入库、出库、还库、需求信息的输入等。 （2）库存管理的各种信息的查询、修改和维护。 （3）设备采购报表的生成。 -The main function of this system includes the following points: (1) inventory management of all kinds of information input, including inbound, outbound, but also libraries, demand information input and so on. (2) inventory management, a variety of information queries, modify and maintain. (3) The equipment purchase report generation.
