The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

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 ...

There was a time when building electronics and building software were two distinct activities. These days, almost any significant electronic project will use a CPU somewhere, or — at least — could.
