crDELAY macro

croutine. h @code{c} crDELAY( CoRoutineHandle_t xHandle, TickType_t xTicksToDelay ); @endcode Delay a co-routine for a fixed period of time. crDELAY can only be called from the co-routine function itself - not from within a function called by the co-routine function. This is because co-routines do not maintain their own stack. Example usage: @code{c} // Co-routine to be created. void vACoRoutine( CoRoutineHandle_t xHandle, UBaseType_t uxIndex ) { // Variables in co-routines must be declared static if they must maintain value across a blocking call. // This may not be necessary for const variables. // We are to delay for 200ms. static const xTickType xDelayTime = 200 / portTICK_PERIOD_MS; // Must start every co-routine with a call to crSTART(); crSTART( xHandle ); for( ;; ) { // Delay for 200ms. crDELAY( xHandle, xDelayTime ); // Do something here. } // Must end every co-routine with a call to crEND(); crEND(); } @endcode
