/**************************** IMPORTANT NOTE **********************************
|
||||
* *
|
||||
* Rationale for "xx_TASK_STKSIZE/4": uC/OS-III manages task stack in terms *
|
||||
* of CPU_STK elements which, on a 32-bit target, are something like uint32_t,*
|
||||
* that is, one CPU_STK elements takes four bytes. *
|
||||
* *
|
||||
* Now, the majority of the world manages stack in terms of *bytes* and this *
|
||||
* leads to an excessive RAM usage if not properly managed. For example, if *
|
||||
* we have, say, xx_TASK_SIZE = 128 with these odd CPU_STK elements we end *
|
||||
* up eating 128*4 = 512 bytes. *
|
||||
* The simple workaround for this is dividing the stack size by four. *
