The present invention provides a method and apparatus for converting building block programming into a program code. The method comprises: setting up building blocks including input parameters, wherein the building blocks mean statement units in the building block programming; setting up a configuration file for converting the building blocks into program codes, wherein the configuration file comprises a plurality of code regions and subprogram codes respectively set up in the plurality of code regions; and converting the building blocks into corresponding program codes according to the subprogram codes and the input parameters respectively set up in the plurality of code regions. The problem in the prior art that the building block programming cannot be applied to different electronic modules is solved.
