利用提供的uc-os工程，實(shí)現(xiàn)兩個(gè)任務(wù)之間的通信。要求自行建立兩個(gè)任務(wù)TaskA和TaskB，利用進(jìn)程間通信工具mailbox進(jìn)行實(shí)現(xiàn)，任務(wù)A定期發(fā)送（post）給任務(wù)B你的學(xué)號(hào)，和一個(gè)計(jì)數(shù)碼，計(jì)數(shù)碼每次發(fā)送自增1；任務(wù)B掛起（pend）在相同的mailbox上，接收到任務(wù)A從mailbox發(fā)送的數(shù)據(jù)后，打印出來你的名字+從任務(wù)A接收到的數(shù)據(jù)。

要求：

提供任務(wù)A和任務(wù)B輸出的結(jié)果，任務(wù)A要打印出你的學(xué)號(hào)和序列號(hào)和一串A，任務(wù)b要打印出你的名字、學(xué)號(hào)和序列號(hào)以及一串B。

例如：

任務(wù)A打�。�

“ 學(xué)號(hào)：012345678：序列號(hào) 20—AAAAAAAAAAA”

任務(wù)B打�。�

“張某甲：學(xué)號(hào)02345678：序列號(hào)20----BBBBBBBBBBBBB”

* used. The compiler should not generate any code for this statement.
* 2) Interrupts are enabled once the task start because the I-bit of the CCR register was
* set to 0 by 'OSTaskCreate()'.
