Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.
See also Fig. 1; Embedded graph system based on household computerized embroidery machine of the present invention comprises structure module, function entrance address mapping table, real function body memory module and the execution module that points to function; Said function entrance map addresses is set up according to the structure module of pointing to function; Execution module is realized the execution of interface redirect and interface action according to the real function body of mapping table and interface number execution real function body memory module storage.Should realize a kind of pointer structure body that points to function based on the use through the C language pointer of the embedded graph system of household computerized embroidery machine; And set up a function entrance address mapping table with this structure, number carry out the real function body according to mapping table and interface and realize interface redirect and interface action execution.Concrete implementation is following:
1, point to the structure of function:
struct?Screen
{
void(*ShowScreen)(void)；
void(*ClickKey)(void)；
}；
2, function entrance address mapping table:
struct?Screen?ScreenTable[]＝
{
{
ShowScreen0，
ClickKey0，
}，
{
ShowScreen1，
ClickKey1
}，
{
ShowScreen2，
ClickKey2
}，
{
ShowScreen3，
ClickKey3
}，
}；
3, real function body:
Void ShowScreen0 (void) // page zero explicit function body
{
The run time version * that/* comprises for the real function body here/
}
The empty part of void ClickKey0 (void) // page zero is carried out the function of movement body
{
The run time version * that/* comprises for the real function body here/
}
Void ShowScreen1 (void) // the 1st page explicit function body
{
The run time version * that/* comprises for the real function body here/
}
