C/C++语言编程 基于（英蓓特）STM32V100的串口程序
This example provides a description of how  to use the USART with hardware flowcontrol and communicate with the Hyperterminal.First, the USART2 sends the TxBuffer to the hyperterminal and still waiting fora string from the hyperterminal that you must enter which must end by '\r'character (keypa ...
开发工具 Arduino学习笔记4_Arduino软件模拟PWM
注:1.这篇文章断断续续写了很久,画图技术也不精,难免错漏,大家凑合看.有问题可以留言.
     2.论坛排版把我的代码缩进全弄没了,大家将代码粘贴到arduino编译器,然后按ctrl+T重新格式化代码格式即可看的舒服.
一、什么是PWM
PWM 即Pulse Wavelength Modulation 脉宽调制波，通过调整输出信号占空 ...
开发工具 Arduino应用_Arduino连接超声波传感器测距
超声波传感器适用于对大幅的平面进行静止测距。普通的超声波传感器测距范围大概是 2cm~450cm，分辨率3mm（淘宝卖家说的，笔者测试环境没那么好，个人实测比较稳定的 距离10cm~2m 左右，超过此距离就经常有偶然不准确的情况发生了，当然不排除笔者技术 问题。）
测试对象是淘宝上面最便宜的SRF-04 超声波传感器，有四个脚 ...

可编程逻辑 PCB Design Considerations and Guidelines for 0.4mm and 0.5mm WLPs
Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This article presents some PCB designconsidera ...

可编程逻辑 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 ...
可编程逻辑 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 ...
