USB interface working principle
Time:2021-03-16 Views:2232
USB interface is an external bus standard, which is used to regulate the connection and communication between computer and external devices. USB interface has plug and play and hot plug functions. USB interface can connect 127 kinds of peripherals, such as mouse and keyboard. USB was launched in 1996 by Intel and other companies at the end of 1994. It has successfully replaced serial port and parallel port. It has become a necessary interface for today's computers and a large number of electronic intelligent devices.
USB version has experienced many years of development, for most engineers, the main obstacles to develop USB2.0 interface products are: facing the complex USB2.0 protocol, writing their own USB device driver, familiar with MCU programming. This not only requires considerable VC programming experience, but also can write USB interface hardware (Firmware) program, so most people give up developing their own USB products. In order to simplify the complex problems, some connector manufacturers specially designed USB2.0 protocol conversion module. The usb20d module can be regarded as a converter of USB2.0 protocol, which converts the USB2.0 interface of the computer into a transparent parallel bus, just like the single chip microcomputer bus, so that the design of USB2.0 products can be completed in a few days.
