The fast_math library is a collection of algorithms that are faster than the default code. These algorithms are to be used when you are in a need for speed. Only tested on Arduino UNO R3 as one of the ...

There’s a long history of devices originally used for communication being made into computers, with relay switching circuits, vacuum tubes, and transistors being some well-known examples. In a smaller ...

A 7-segment display is commonly used in electronic display devices for decimal numbers from 0 to 9 and, in some cases, basic characters. The use of light-emitting diodes (LEDs) in seven-segment ...

Renesas’ RL78/L23 is a low-power 16-bit MCU with built-in segment LCD, capacitive touch, dual-bank flash for FOTA, and a wide 1.6–5.5 V operating voltage range. It targets HMI appliances, metering, ...

而一般在开发和维护过程中还需要和设备交互的链路，通常做法是使用 UART ，但是这样需要多预留接口不是很方便，我们可以使用 CDC 虚拟出一个串口来用于和设备通讯进行管理。这样 ALL IN USB 非常方便。所以本文继续在 UVC+UAC( 扬声器 + 麦克风 ) 的复合设备的 ...
