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 ...
可编程逻辑 protel 99se 使用技巧以及常见问题解决方法
protel 99se 使用技巧以及常见问题解决方法:里面有一些protel 99se 特别技巧,还有我们经常遇到的一些问题!如何使一条走线至两个不同位置零件的距离相同?
您可先在Design/Rule/High Speed/Matched Net Lengths的规则中来新增规则设定,最后再用Tools/EqualizeNet Lengths 来等长化即可。

可编程逻辑 XAPP440 - Xilinx CPLD的上电性能
Applying power to a standard logic chip, SRAM, or EPROM, usually results in output pinstracking the applied voltage as it rises. Programmable logic attempts to emulate that behavior,but physics forbids perfect emulation, due to the device programmability. It requires care tospecify the pin behavio ...
可编程逻辑 XAPP806 -决定DDR反馈时钟的最佳DCM相移
This application note describes how to build a system that can be used for determining theoptimal phase shift for a Double Data Rate (DDR) memory feedback clock. In this system, theDDR memory is controlled by a controller that attaches to either the OPB or PLB and is used inan embedded microproces ...
