电子设备之间的通信就像人类之间的交流，双方都需要说相同的语言。在电子产品中，这些语言称为通信协议。 之前有单独地分享了SPI、UART、I2C通信的文章，这篇对它们做一些对比。 串行 VS 并行 电子设备通过发送数据位从而实现相互交谈。位是二进制的 ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They ...

Strictly speaking, a Theremin uses a pair of antennae that act as capacitors in a specific R/C circuit. Looking at [aritrakdebnath2003]’s MIDI THEREMIN, we see it works differently, but it does play ...

Waveshare ESP32-H2-Zero is a tiny USB-C development board based on Espressif Systems' ESP32-H2 RISC-V SoC with Zigbee, Thread ...

如果classpath中存在多个jar包都申明了同一个接口的相同实现类，或者同一个jar包被不同类加载器加载多次，会导致同一个实现类被多次加载和实例化，可能导致单例失效或资源冲突。 SPI 即 Service Provider Interface ，也就是“服务提供者的接口”。 SPI 将服务接口和 ...

In this tutorial, we will learn how to install multiple versions of the ESP32 board package in the Arduino IDE. Once set up, you’ll have the option to choose a specific version of the ESP32 package ...

25赛季中，平衡步兵在RoboMaster赛场上有不少亮眼表现。与传统四轮比赛机器人不同，平衡步兵具有双轮腿的构型。它通过轮腿实现平衡、移动，在复杂地形下实现平稳快速的全向运动，并且轻松实现飞坡、上下台阶等高机动性的动作。这些功能是否能很好地实现，很大程度上依赖电控设计编写的运动控制算法。如果你有相关兴趣或学习经历、有意愿加入电控部参与平衡步兵机器人的研发维护，欢迎在招新报名阶段向我们说明。
