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 ...

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 ...

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 ...

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 ...

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 ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using the ...

DoNews3月10日消息，在世界嵌入式展览会前夕，Arduino宣布即将推出其最新平台Arduino® VENTUNO™ Q，旨在推动边缘AI的普及。 VENTUNO Q的名称源自意大利语单词“21”，该平台延续了广受欢迎的Arduino® UNO™系列的经典基因，同时也象征着Arduino在本月晚些时候即将迎来成立21周年之际迈入成熟发展阶段。
