单片机编程 DUAL DIGITAL ISOLATORS
The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB layout, the channels are orientedin the same direction in the ISO7220 and in opposite directions in the ISO7221. These devices have a logic inputand output buffer separated by TI’s silicon-dioxide (SiO2) isolation barrier ...
单片机编程 MCU(单片机)对可控硅的控制
MCU(单片机)对可控硅的控制:交流市电控制――MCU对可控硅的控制 郭江辛 07-23-03在用可控硅对交流市电控制中,主要注意以下几个方面:一, 同步信号 (弄不好都会产生不均匀的斩波,控制白炽灯表现为灯闪)1) 清楚同步信号在交流周期中的位置,最好在交流零点选取.在一些阻容降压对MCU 供电电路中,最好直接在交流电源两端 ...

教程资料 Create a 1-Wire Master with Xilinx PicoBlaze
Abstract: Designers who must interface 1-Wire temperature sensors with Xilinx field-programmable gate arrays(FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable softwarementioned in this document can also be used as a starting point to connect other 1-Wir ...
教程资料 Verilog_HDL的基本语法详解(夏宇闻版)
        Verilog_HDL的基本语法详解(夏宇闻版):Verilog HDL是一种用于数字逻辑电路设计的语言。用Verilog HDL描述的电路设计就是该电路的Verilog HDL模型。Verilog HDL既是一种行为描述的语言也是一种结构描述的语言。这也就是说,既可以用电路的功能描述也可以用元器件和它们之 ...
