  • I have tried to modify my sample above as follows:
void    sample_callback()   { led = !led;  event_flags.set(GET_SAMPLE);}

On LPC1768 it works OK.

  • Make sure the most significant bit of an EventFlag is not set in the program. Otherwise an osFlagsError message is generated:
/** The EventFlags class is used to control event flags or wait for event flags other threads control.

 @note
 EventFlags support 31 flags. The MSB flag is ignored. It is used to return an error code (@a osFlagsError).

 @note
 Memory considerations: The EventFlags control structures will be created on the current thread's stack, both for the Mbed OS
 and underlying RTOS objects (static or dynamic RTOS memory pools are not being used).
