Strictly speaking, a Theremin uses a pair of antennae that act as capacitors in a specific R/C circuit. Looking at ...

Abstract: Lossy image compression is a fundamental technology in media transmission and storage. Variable-rate approaches have recently gained much attention to avoid the usage of a set of different ...

Are you unable to use your touchpad, biometric, touchscreen, or any other interactive on your PC? If the I2C HID Device Driver is not working on Lenovo, Dell, Acer, ASUS, etc laptop, then follow this ...

很多人不知道怎么看着时序图写程序，下面结合一个非标准的I2C器件，教大家如何写一个高效的IO模拟I2C时序。 观察该时序，具备I2C的开始信号，I2C的结束信号，I2C的应答、非应答、响应应答，以及写字节和读字节的基本操作时序。 下面，我们一步一步分析。

UART、I2C、SPI都是常见的低速板级通信协议，目前主流的SoC都内置了这些通讯协议的控制器，同样，各种传感器、Touch控制器、指纹模块、蓝牙模块、WIFI模块也都兼容这三种通信方式的一种或几种。 下面分别说下： UART UART一般由TXD、RXD、GND三根线组成，是一种 ...

Hamza is a certified Technical Support Engineer. The I2C HID driver failure occurs when the system fails to initiate the device, commonly due to a failed request for an HID descriptor. This often ...

Abstract: The purpose of this paper is to design and simulate a Protocol Conversion Unit (PCU) for seamless communication between the two widely accepted serial communication protocols SPI and I2C.
