BE�Y Each port #defines ‘BaseType_t’ to equal the most efficient data type for that processor. You may obtain a copy of the license at. That is, the minimum free stack space there has been (in words, so on a 32 bit machine a value of 1 means 4 bytes) since the task started.

Use Git or checkout with SVN using the web URL. When task notifications are being used as a binary or counting semaphore equivalent then the task being notified should wait for the notification using the ulTaskNotificationTake() API function rather than the xTaskNotifyWait() API function. Set xTask to NULL to check the stack of the calling task.
