Command ;; - Page Refresh
 
Description Refresh the current page. Can be used for refreshing a page after a series of entity updates
without knowing which page is showing.
LOAD(VOLTS,"34");LOAD(AMPS,"100");;
 
Syntax/Parameters ;; = SHOW(this_page);
 
Options Page Refreshing - v47.00
 A new mode has been added for pages which allows for either
  1/ All entities to be redrawn on a page when a double semicolon (;;) refresh is encountered
     (default), or
   2/ Only the entities that have been modified since last refresh to be redrawn when a double
     semicolon (;;) is encountered.
   A SHOW(page); command will always redraw all the entities on a page.
   STYLE(name,PAGE) { update=all; } // default: refreshes all entities on a ;;
   STYLE(name,PAGE) { update=changed; } // refreshes only changed entities on a ;;
 
Example LOAD(VOLTS,"34");LOAD(AMPS,"100");;

FUNC(TestFunc)
{
SHOW(But1);
LOAD(AMPS,"50");
;;
}

 SHOW() and HIDE() Groups of Entities

18 Feb 14 

Show

Added array of pointer support to SHOW() and HIDE() commands.
This allows for groups of entities to be shown and hidden on a page by passing the single name for the array of pointers.

VAR(group>"",PTR,3);
LOAD(group.0>"img1");
LOAD(group.1>"text1");
LOAD(group.2>"shape1");

HIDE(group);; // Hide img1, text1, shape1
SHOW(group);; // Show img1, text1, shape1

Test code:

STYLE(stPage,PAGE){}
STYLE(stCirc1,DRAW){type=circle;col=white;width=1;back=red;}
STYLE(stCirc2,DRAW){type=circle;col=white;width=1;back=green;}
STYLE(stCirc3,DRAW){type=circle;col=white;width=1;back=blue;}
STYLE(stCirc4,DRAW){type=circle;col=white;width=1;back=yellow;}
STYLE(stText,TEXT){ maxRows=4; ySpace=4; }
STYLE(stBox,DRAW){type=box;col=lime;width=1;}

VAR(x,49,S32); VAR(y,49,S32);

PAGE(pgTest,stPage)
{
LOAD(x,49); LOAD(y,49); DRAW(circle1,80,stCirc1,x,y);
CALC(x,DISPX,50,"-"); LOAD(y,50); DRAW(circle2,60,stCirc2,x,y);
LOAD(x,90); CALC(y,DISPY,90,"-"); DRAW(circle3,150,stCirc3,x,y);
CALC(x,DISPX,70,"-"); CALC(y,DISPY,70,"-"); DRAW(circle4,100,stCirc4,x,y);

CALC(x,DISPX,2,1,"/-"); CALC(y,DISPY,2,1,"/-");
DRAW(box1,DISPX,DISPY,stBox,x,y);
TEXT(text1,"",stText,x,y);
KEY(key1,fncKey1,DISPX,DISPY,TOUCH,x,y);
}
LOAD(text1,
"Vers: ",VERS_IAPP,"\\0d\\0a",
"Width: ",DISPX,"px\\0d\\0a",
"Height: ",DISPY,"px\\0d\\0a",
"Rotate: ",DISPR,"deg"
);
SHOW(pgTest);

VAR(toggle,0,U8);
VAR(group>"",PTR,4);
LOAD(group.0>"circle1");
LOAD(group.1>"circle2");
LOAD(group.2>"circle3");
LOAD(group.3>"circle4");

FUNC(fncKey1)
{
//IF(toggle==0?[LOAD(toggle,1);HIDE(circle1,circle2,circle3,circle4);;]:[LOAD(toggle,0);SHOW(circle1,circle2,circle3,circle4);;]);
IF(toggle==0?[LOAD(toggle,1);HIDE(group);;]:[LOAD(toggle,0);SHOW(group);;]);
}

 Show/Hide of I/O Interrupts

06 Sep 13 

Show

* I/O interrupts are now handled the same as other interrupts therefore can now be enabled / disabled via the use of SHOW() / HIDE()

49.03

 HIDE / SHOW( INT ) - Pending interrupts are now processed when an interrupt entity is unhidden.

01 Jun 12 

Show

Pending interrupts are now processed when an interrupt entity is unhidden.
* The supported interrupts are RS2RXC, RS4RXC, AS1RXC, AS2RXC, DBGRXC, TWIRXC, SPIRXC, USBRXC, TIMER0..TIMER9
* Example
INT( intRs2, RS2RXC, fncRs2Rx ); // Create RS2 receive interrupt
...
HIDE( intRs2 ); // Hide the interrupt
...
SHOW( intRs2 ); // Show (Enable) interrupt and process pending interrupts
* If you don't want to process any pending interrupts when you show the interrupt then RESET the interrupt first
* Example
INT( intTmr0, TIMER0, fncTmr0 ); // Create RS2 receive interrupt
...
HIDE( intTmr0 ); // Hide the interrupt
...
RESET( intTmr0 ); // Clear any pending interrupts
SHOW( intTmr0 ); // Show (Enable) interrupt for future interrupts

48.24

 IF() - A page name as well as the existing function name are now supported in the IF() then/else statement.

10 Mar 12 

Show

A page name as well as the existing function name are now supported in the IF() then/else statement, thus allowing a RUN(function) or SHOW(page) to be directly called.
K00-K30 are now supported in IF() test, eg IF( K03 = 1 ? func );

27.00

 Smaller Pages / Pop Ups - Added popup pages.

10 Sep 10 

Show

Added popup pages - ie smaller than 480 * 272.
When smaller page is displayed SHOW(SmallPage); it is overlayed onto the existing page which is then ‘frozen’. Use SHOW(PREV_PAGE); to return.

27.00

 Entity Pointers - Entity pointers have been added.

10 Sep 10 

Show

Entity pointers have been added.
STYLE( PtrData, DATA ) { type = pointer; }
VAR( EntPtr1, PtrData );

To set/change which entity the entity pointer is pointing to you enclose its name in quotes.
LOAD( "EntPtr1", "Var1" ); // Set EntPtr1 to point to "Var1"

To access the entity pointed to by the entity pointer, do not enclose is quotes.
LOAD( EntPtr1, "ABC" ); // Load the Entity pointed to
by EntPtr1 with "ABC"

The following commands now support entity pointers:
> LOAD(name|ptr|"ptr",num|"txt"|var|ptr,...);
> CALC(var|ptr,var|ptr,num|var|ptr,"op");
> TEXT(name|ptr,"txt"|var|ptr,...);
> IF(var|ptr op num|"txt"|var|ptr ? func|func_ptr : func|func_ptr);
> KEY(name,func|func_ptr,...);
> INT(name,buf,func|func_ptr,...);
> SHOW(name|ptr,...);
> HIDE(name|ptr,...);
> RUN(name|func_ptr,...);
> IMG(name|img_ptr,lib|img_ptr,...);

See the tu480.mnu file for an example of using pointers to update images representing CNTSECS.

 SHOW ;; HIDE - Added ';;' command to redraw current page

17 Aug 10 

Show

Added ';;' command to redraw current page
e.g. HIDE(Btn1);; same as HIDE(Btn1);SHOW(THIS_PAGE);

 Multiple SHOW HIDE - Multiple entities can now be handled in one command.

17 Aug 10 

Show

Multiple entities can now be handled in one command:
eg SHOW(Ent1,Ent2,Ent3 ... EntN);
eg HIDE(Ent1,Ent2,Ent3 ... EntN);
eg DEL(Ent1,Ent2,Ent3 ... EntN);
eg RESET(Ent1,Ent2,Ent3 ... EntN);
eg RUN(Func1,Func2,Func3 ... FuncN);
eg INC(File1,File2,File3 ... FileN);
