The invention relates to a method for programming an update program through a USB interface and a controller, and the method for programming the update program through the USB interface comprises thesteps: detecting whether USB equipment is connected or not; when the USB equipment is accessed, detecting whether an updating program is stored at a specific position of the USB equipment or not; whenan updating program is stored at a specific position of the USB equipment, copying the updating program to the local and replacing the local original program; and updating a local corresponding program by utilizing the updating program. According to the method for programming the updating program through the USB interface, the USB equipment is directly connected with the controller, and the software program in the controller is directly updated through the USB interface. The programming process is simplified, programs are updated conveniently and quickly, the programs can be updated in batches, the program updating efficiency is improved, and the working state of the controller can be known in time in the program programming process.
Description
technical field [0001] The invention relates to the technical field of burning embedded software programs, in particular to a method for burning and updating programs through a USB interface and a controller. Background technique [0002] At present, micro-programmable controllers generally do not display digital tubes or LCD screens due to their small size, and there are no buttons to provide interactive control. The industry generally uses Ethernet or serial ports to connect computers to burn programs into the memory modules of the controllers. , in the specific operation, the program to be burned must be stored in the computer first, and then connected to the controller through the Ethernet or serial port of the computer, so as to carry out the program burning process of the controller through the computer. The existing programming process is complicated to operate, and the efficiency of updating the program is low, and it is impossible to know the working state of the co...
