Embodiment
[0035] An embedded software upgrading method based on the CANOPEN protocol is applied to a system composed of a host computer and a lower computer connected through a CAN bus network. The topology of the above system is as follows figure 1 As shown, it includes an upper computer 1, a CAN bus network 3 and a plurality of lower computers 2, wherein the upper computer 1 is a PC that downloads programs and is connected to the CAN bus network 3 through a USBCAN adapter 4. The upper computer 1 runs the upper computer program, and its main function is to analyze application program files, such as HEX, BIN, and S19 files, and send useful data bytes to the lower computer, and can also display the transmission process and transmission results. The lower computer 2 is a terminal for receiving data from the upper computer and updating the program, and is connected to the upper computer 1 through the CAN bus network 3 .
[0036] The communication protocol of this method adopts the CANopen...
