Hi All,
I am using MK60F120, MQX4.0.1, cw10.4.
And now I create a timer to generate a interrupt every 50ms.
When I start the timer in the main task, it works fine. But when I start the timer in a button interrupt, it does not work.
I am using following code to start the timer.
*TimerID = _timer_start_periodic_every_ticks(key_generator, 0, TIMER_ELAPSED_TIME_MODE,Ticks);
Is there something wrong or I can't start a timer in a interrupt?
Thank you.

Hi Daniel,
MQX timer functions do a call to _lwsem_wait(), under some conditions. _lwsem_wait() can't be called from an isr. Therefore, MQX timer functions should not be called from an isr.
