Computer system and related method for generating program codes describing relationships of numerous function names and numerous control codes of a device

A computer system for generating program code for generating firmware of a device, the program code describing relationships between a plurality of function names of the device and a plurality of control codes, the control codes receivable by the device from a second device for commanding the device to execute a plurality of functions of the device named by the plurality of function names, the computer system comprising:

• a memory;
• a processor programmed for storing the plurality of function names and the plurality of control codes into the memory;
• a relating unit accessing the memory for mapping the plurality of function names to the plurality of control codes;
• a first detecting unit accessing the memory for detecting if one of the plurality of function names corresponds to more than one control code of the plurality of control codes;
• a second detecting unit accessing the memory for detecting if one of the plurality of control codes corresponds to more than one function name of the plurality of function names;
• a first message unit for generating a warning message when the first detecting unit detects one of the plurality of function names corresponds to more than one control code of the plurality of control codes;
• a second message unit for generating a duplicated function name error message when the second detecting unit detects one of the plurality of control codes corresponds to more than one function name of the plurality of function names;
• and
• a processing unit for generating the program code describing the relationships only when no unallowable warning message is generated by the first message unit and no error message is generated by the second message unit, and storing the program code into the memory.

A procedure of product development by using a computer system having a processor and memory, the procedure comprising:

• receiving a first product, first program code corresponding to the first product, a user interface, and an encoder;
• inputting into the memory a plurality of function names of the first product corresponding to functions of the first product executable by the first product through the user interface and relationships between a plurality of control codes of a second product and the plurality of function names of the first product, the plurality of control codes receivable by the first product for commanding the first product to execute the functions named by the plurality of function names;
• the processor detecting if a control code of the plurality of control codes corresponds to more than one function name of the plurality of function names, or if a function name of the plurality of function names corresponds to more than one control code of the plurality of control codes;
• when detected that a control code of the plurality of control codes corresponds to more than one function name of the plurality of function names, or if a function name of the plurality of function names corresponds to more than one control code of the plurality of control codes, changing the relationship or determining that current relationship is acceptable through the user interface;
• and
• utilizing the encoder to convert the relationships processed by the user interface and the first program code into second program code for the second product, the processor storing the second program code into the memory.
