1. remove the old msg queue and queue:
i. msg queue is not a common and reusable/flexible component(need user to config the msg pool size and this componet can only be used by tos_queue)
ii. tos_queue can only deliver the pointer message(cannot do a memory buffer deliver)
2. add ring queue(tos_ring_q) componet
rinq queue can be reused by tos_chr_fifi/tos_msg_q/tos_mail_q as the foundational data container
3. add message queue(tos_msg_q)
a little like the old queue mechanism, supply the capability to deliver a pointer message
4. add mail queue(tos_mail_q)
supply the capability to deliver a memory buffer
5. add binary heap(tos_bin_heap)
the basement componet to implement priority queue
6. add priority queue(tos_prio_q)
can be reused by the priority message/mail queue as the foundational data container.
7. add priority message queue(tos_prio_msg_q)
a message(pointer) deliver mechanism, supply the capability of delivering the message with priority(message with higher priority comes faster to the pender than with lower)
8. add priority mail queue(tos_prio_mail_q)
a mail(memory buffer) deliver mechanism, supply the capability of delivering the mail with priority(mail with higher priority comes faster to the pender than with lower)
tos_task_create_dyn: create task with dynamic allocated task handler and stack
tos_task_walkthru: API to walk through the statistic list of all the existing task
tos_task_curr_task_get: get current running task handler
tos_mmheap_check: get the information of the heap(space that is free and used)
tos_mmheap_pool_check: get the information of a pool
TOS_CFG_MMHEAP_DEFAULT_POOL_EN: enable the default pool of the heap(if user not set this, a default of 1u is set). if you wanna disable the default pool, you should call tos_mmheap_pool_add to add your own pool of the heap before tos_mmheap_alloc is called.
currently we DONOT have a 51822 xxAC(we only have xxAA of which the ram is only 16k which is too small to porting nimble, means currently the nimble ble on 51822 probably may not work). xxAC is coming soon(on EMS), I will make nimble on 51822 xxAC later.
