Problems solved by technology

[0004] 1. Due to the serial method to transmit data stream, compared with parallel and USB, the transmission data rate is relatively slow, which wastes time in production and user upgrade and use, and the efficiency is low;
[0005] 2. Since the RS232 interface needs to be integrated in the electronic equipment, it will increase the hardware cost of the electronic equipment;
[0006] 3. Many existing PCs and mobile PCs are no longer equipped with serial interfaces for users. Therefore, it is inconvenient to use serial interfaces for software upgrades;
[0007] 4. Some electronic devices are not upgraded through the VGA interface, and the electronic devices must be turned on to upgrade, which is inconvenient to operate

Abstract

A software upgrade device used for converting USB interface to be VGA interface consists of USB interface connected to electronic unit containing upgrade data and used to fetch upgrade data, data conversion unit connected to USB interface and used for converting parallel upgrade data read in by USB interface to be serial TX data stream and RX data stream as well as for outputting converted data streams out, VGA interface connected to electronic unit to be software-upgraded and used for receiving said TX and RX data streams and for outputting received data stream to electronic unit to be software-upgraded.

Description

technical field [0001] The invention relates to software upgrading technology, in particular to an upgrading device for converting a USB interface into a VGA interface, and a software upgrading method using the upgrading device. Background technique [0002] Nowadays, the use of electronic equipment is more and more extensive, has spread all over the various places of people's life, work and leisure, for example, computer, business communication, satellite TV set-top box, etc. In order to perfect and improve the performance and usage functions of the electronic device, people usually upgrade the driver software or application software of the electronic device. [0003] Because most of the interfaces that existing electronic devices have to exchange data with the outside world are RS232 interfaces, or VGA interfaces, or USB interfaces, therefore, what generally adopts for software upgrading is to utilize the serial port RS232 serial interface (abbreviated as serial port) dire...
