user press ok before going to next loop

[gabriellimhj]

Hi, actually im trying to do a program when its receiving data from serial port. it light up the LED. So i wanna make it like user have to press a button eg. ok before going to next loop. Meaning the LED is be always lighted until user press ok.

I cleaned up your VI so it's readable then added a simple loop to do what  you want.

You should add a loop delay so you don't eat up CPU time.

thank you. i got it.

Make sure the "continue" button is latch action (right-click..mechanical action...latch when released).

Personally, I would probably use an event structure instead. Do you really need to configure the serial port with every iteration of the loop? How often do the inputs change? Most of the controls are not even visible, replace them with diagram constants instead.

but actually i want to make when the led is on then i need to press and when led is off i dont have to press. for your program i have to press for both case.

how to instantly off the LED after i press ok? i tried but seems like its lagging. offing each 1 by 1.

Hello,

Changed it for you.

Though I don't think it will make any sense to do this.

When you press the button it will only put the leds off for 200ms.

Because after the iteration the program will measure the leds again, and put it instant on.
