Sometimes GPIO not work

[wsywsya119]

Hi everyone.
I use the newest Arduino.cs code by lafrank which help reducing the CPU usage.

And test LED blink code like this:
Controller.digitalWrite(doorPin, Arduino.HIGH);
Thread.Sleep(2000);
Controller.digitalWrite(doorPin, Arduino.LOW);

It works at start but sometimes not blink after a while.

I observed the LED on the board is always on with the old Arduino.cs
However. Use the newest Arduino.cs is not.
Any idea about it? Thanks.

How about do like this:
Controller.digitalWrite(doorPin, Arduino.HIGH);
Thread.Sleep(2000);
Controller.digitalWrite(doorPin, Arduino.LOW);
Thread.Sleep(2000);

I tried but still not work.
I did't call my blink function frequently. So maybe the problem is not the Thread.sleep.
I remove the sleep and just use Arduino.HIGH, Arduino.LOW to turn it on/off.
Still got the same result. Sometimes the LED is not responded as my command.

BTW. I download the entire demo project and test it.
When I click Turn off/on D13 Led button. It work fine at start.
But a little delay after a while. The delay time is about 1~3 second.
