直接数字合成 - DDS是一个非常重要的概念，也是电赛中要考察的技能，一般都使用FPGA + 高速DAC或高集成度的DDS芯片来实现，得到几十MHz的模拟信号。实际上大多数的应用场景需要产生的信号在100KHz以内，完全可以用单片机的程序来实现，如果单片机内部有DAC ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

The good thing about computers is they do your work for you, right? If you are a programmer, that doesn’t always seem to be a true statement. [Runtimemicro] has the answer, at least if you are writing ...

在即将开幕的世界嵌入式展览会上，Arduino公司宣布将推出全新边缘AI开发平台——Arduino® VENTUNO™ Q。这款以意大利语"21"命名的新品，既延续了UNO系列的经典设计语言，也标志着Arduino在成立21周年之际正式迈入技术成熟期。平台通过整合高性能AI计算与实时控制能力，为开发者构建物理世界智能系统提供了全新解决方案。 VENTUNO Q采用独特的双脑架构设计，搭载高通跃龙™ ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

As a result, remote control technologies are being widely adopted across various sectors. Among the many components used in ...

昨天认识了Arduino，今天来看看Arduino的各种常用开发板。 它有各种型号的，如Arduino Uno、Arduino Leonardo、Arduino101、Arduino Mega 2560、Arduino Nano、Arduino Micro、Arduino Ethernet、ArduinoYún、Arduino Due、Arduino33 ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...
