Embedded Firmware Online Upgrade System Based on Infrared Communication
After the development of embedded products,it is often necessary to frequently upgrade firmware to better adapt to changes in the environment and meet operational requirements.Traditional firmware upgrades typically require disassembling the product casing and having professionals rush to the site(using JLINK or other programmers)to burn the firmware into the embedded system.To solve the after-sales maintenance problems of frequent disassembly of product shells and on-site upgrades by professional personnel,IAP firmware upgrades are often adopted.Although this method can solve the after-sales maintenance problems,it requires embedded systems to have interfaces such as serial ports,USB ports,and network ports.Remote upgrades can be achieved through computers,USB drives,networks,and other methods.For large quantities of small embedded systems,adding such interfaces will significantly increase product costs.To address this issue,an embedded firmware online upgrade system based on infrared communication is proposed,which has the advantages of simple circuit design,strong anti-interference ability,no need for wiring,and low cost.
