The invention relates to a method for judging whether IO ports conflict or not by using macro compiling, and belongs to the field of computers. The method comprises the following steps: initializing an IO port; defining an IO (Input / Output) port as a certain constant by using a macro definition # defeine; using macro compilation statements; when the IO port is initialized, if the IO port is repeatedly initialized, judging that the system cannot be compiled. In an industrial control system for controlling stepping motors by utilizing an MCU (Microprogrammed Control Unit), as the system needs tocontrol six stepping motors, twelve sensors and various peripherals, after IO (Input / Output) ports are distributed on hardware, the system cannot run due to repeated initialization of a certain IO port during programming. After the method is used, the phenomenon of repeated conflict of IO ports is avoided, and meanwhile, the size of compiled programs is reduced by 5%.
Description
technical field [0001] The invention belongs to the field of computers and relates to a method for judging whether IO ports conflict by using macro compilation. Background technique [0002] Embedded systems need to configure and set the IO ports of the MCU. For systems with hundreds of IO ports, how to efficiently maintain and manage these IO ports has become a difficult problem for programmers. Macro conditional compilation is a technology commonly used in programming languages such as C to judge according to conditions and selectively compile the code into the system. It can be used to judge and compile the IO port of the MCU. [0003] Existing IO port management is usually based on a certain development platform (the platform is responsible for IO port management) or manually maintained by programmers. The former method is highly dependent on the development platform and has poor versatility; the latter method greatly increases the workload of programmers, and it is e...
