The application provides a controller online parameter configuration method and system, a program burning method and device. The controller parameter configuration method is to read parameter information in a controller program according to a data reading instruction; the parameter information is stored in a specified storage address in the controller; when it is needed to modify parameters or functions, the parameter information is modified according to a modification instruction; the modified parameter information is written into the specified storage address in the controller, wherein the modified parameter information replaces the original parameter information. The advantage of this is that the whole program does not need to be recompiled, the user can directly edit the parameter information, the program does not need to be reconstructed, the development period and the maintenance period can be shortened, the user is easier to use, a large amount of repetitive modification and maintenance work can be saved, and development resources can be saved.

The application relates to the technical field of vehicle navigation, and provides a chassis communication protocol configuration method and device, a vehicle navigation terminal and a storage medium. The vehicle navigation terminal acquires the configuration state of the chassis communication protocol of a rear-mounted navigation system, and acquires chassis data messages and target communication protocol identification when the configuration state is not configured. Then, the target communication protocol identification is matched with a plurality of chassis communication protocol information. When there is no target chassis communication protocol information matched with the target communication protocol identification, the chassis data messages are sent to an upper computer, so that the upper computer obtains target chassis communication protocol information according to the chassis data messages and sends the target chassis communication protocol information to the vehicle navigation terminal. The vehicle navigation terminal stores the target chassis communication protocol information and performs integrity check. When the target chassis communication protocol information passes the integrity check, the configuration state is modified to configured. Therefore, the rear-mounted navigation system does not need to be developed for each chassis communication protocol, and the universality of the rear-mounted navigation system is improved.

The application provides a program development method, a program development device and a readable storage medium. The program development method comprises the following steps: acquiring a plurality of instruction codes in a software system; determining an attribute parameter corresponding to any instruction code in the plurality of instruction codes; converting the any instruction code into a component command according to the attribute parameter; combining a plurality of component commands into a first function component, and installing the first function component in a target project.
