A little summary of the establishment of a data dictionary is the establishment of data dictionary these two days. Seeing two ways to build a data dictionary: one is to bring the source code of other similar operating systems to find out which files and functions have. The other is based on existing theoretical books (including "Real-Time Concepts for Embedded Systems") to find MYOS (51) and the future needs of the function and objects. Later I decided to use two ways to build data dictionary these two days used several tools in the process of establishing a data dictionary: Free Mind, with a tree-type MIND MAP structure to help build a data dictionary (maybe my original way! ^ o ^). Take MyOS (51) as the core, then the next layer is a number of folders contained in Myos (51), and then the next layer is the description document, user documentation, development document, source file, and various processes included in each folder. The file name of the figure. The next layer of the source file is the function included in the source code and the public variable. The next layer of the function is the input, output, and call function name of the function. From this, all the functions I need are listed all in the variables. Visio 2003, used to draw chart files. A flowchart including each function, a data flow diagram between a function, a control flow diagram of a system, a status conversion diagram. EditPlus, don't say more! The best editor used to write source code and documentation. (At least I think so!) In addition! I borrowed the source code and document template for version control from SMALL RTOS. as follows/************************************************ *********************************************************** ******** MYOS (51) ** The Real-Time Kernel (for keil c51) **** jiange ** all rights reserved ** ** v0.01 ***** - ------------ File information ------------------------------------ --------------------------------------------**file name: Includedes.h ** Created: Jiang Yi ** Last Date: January 5, 2005 Description: The header file containing other header files.
