"Child Lock" Screen on TM172DCLxxx

Hi Guys,

 

I am planning to implement a "Child lock" screen or lock screen after a x period of inactivity. I have an idea using the backLight timer to trigger a local timer which launch a pop-up screen which I design already. My question is in regards the system flag or timers documentation. I haven't found a proper documentation about those topics. Any ideas??? 

 

I much appreciate your suggestions,

Re: "Child Lock" Screen on TM172DCLxxx

You can find in the follow link an example how you could start a procedur regarding to inactivity

 

Example check for inactivity 

 

And you could check in you code the value of sysBacklight.

0 = Min Backlight active

1 = Backlight on

2 = Timer are running

 

You can adjust the time for sysBacklight via Par_BackLIghtTime

Re: "Child Lock" Screen on TM172DCLxxx

Hi,

 

Thanks for your advise. Finally, I used a structure call  sysLCDPressed which triggers a timer. I could not find any documentation about this, I just tried and worked.

 

 
timer_LCD_Lock(IN:=NOT sysLCDPressed.is_LCD_pressed,PT:=60000);
 
if timer_LCD_Lock.Q then 
var_chck := Video_SendEvent (kWM_KEY, kKEY_VK_F8); 
end_if;
 
Thanks
