Embedded software updating method and system for display device with multiple peripheral devices

Abstract

The present invention discloses an embedded software update method for a display device with multiple peripheral devices, with the main control module of the display device as the core. The main control module contains, in addition to the storage space for the currently running program, new program storage space for all peripheral devices of the device and its own running program. When an external system updates the program for one or more device modules in the display device through a USB concentrator, the new program is transmitted to the main control module through a communication channel and stored in a new program storage area. During this process, the user of the device does not feel anything and can operate normally. Only when certain preset conditions are met will the main control module update the new program to the corresponding program running area of ​​the device in sequence, and then restart the device and switch to the new program to run. The present invention overcomes the problem that the device program is stopped when updating the program in the past, causing the user to interrupt work and wait for the update to be completed.
