Design And Implementation Of Office Automation System Based On B/S

With the rapid development of Chinese economy, intelligent devices in the dailylife of people reflect a more and more important role，but, in embed system with OS，bootloader is so important that it cannot miss，what is more it also have the importantfoundation partly，if not have bootloader the system cannot work.Traditional bootloader mostly is character command for non professional is sodifficult. If you want to modify the profile information，you must get the professiontools，for example serial port line so that it is difficult for non professional. For thisreason a new Visualization bootloader have put forward，The so-called visual bootloader,the main feature is the traditional basis of the bootloader on adding visual features, themain design ideas smartGUI is the use of message passing mechanism similar to thewindows, the first simple drawing point and drawing a line of related functions, thendraw relevant the menus and windows, in this process requires the LCD driver supportrelated to the user through a simple configuration visualization window, enter therelevant boot parameters, you can start any operating system, but also can customizerelated peripheral devices you want to start, this increases the flexibility and scalabilityof the system, another major feature is based on the visualization lwip transplantnetwork protocol stack, transplants are done is to modify lwip code related andunderlying NIC hardware registers to achieve and hardware interfaces, primarily toreceive and transmit data to the two main functional modules, with the support ofnetwork functionality can be achieved remotely start off function systems, remoteupgrade system, remote installation of the system, making it easy to use and flexible.
