USB working principle

USB is an external bus standard that regulates the connection and communication between a computer and an external device. USB interface plug and play and hot plug function. The USB interface can be connected to 127 peripherals such as a mouse and keyboard. USB was successfully introduced in 1996 after the launch of a combination of Intel and other companies in 1996. It has become a must-have interface for today's computers and a large number of smart devices. The USB version has evolved over the years and has grown to version 3.0. [2] For most engineers, the main obstacles in developing USB2.0 interface products are: to face the complex USB2.0 protocol, to write the driver of the USB device, and to be familiar with the programming of the microcontroller. This requires not only considerable VC programming experience, but also hardware (firmware) programs that can write USB interfaces. So most people gave up developing their own USB products. In order to simplify the complicated problems, Xi'an Datai Electronics specially designed the USB2.0 protocol conversion module. The USB20D module can be thought of as a USB 2.0 protocol converter that converts the computer's USB 2.0 interface into a transparent parallel bus, just like a microcontroller bus. So you can complete the design of USB2.0 products within a few days.
