I use FreeRTOS with dsPIC and PIC18 only, but it appears that you made
an obvious mistake.

Your pin is OFF for 200000000 ticks and then for ON for 100 ticks.
If you use a tick rate of 1000 ticks per second, this gives an OFF time
of 55,55 hours and an ON time of 0,1 second.

Even if your tick rate is 1,000,000 ticks per second (I doubt it), you
would need to wait more than 3 minutes to see the LED on for 0,1 ms.

Perhaps you didn't waited enough to see the  LED flash ;)
