單片機(jī)的外部中斷有兩種觸發(fā)方式可選:電平觸發(fā)和邊沿觸發(fā)。選擇電平觸發(fā)時(shí),單片機(jī)在每個(gè)機(jī)器周期檢查中斷源口線,檢測到低電平,即置位中斷請(qǐng)求標(biāo)志,向CPU請(qǐng)求中斷。選擇邊沿觸發(fā)方式時(shí),單片機(jī)在上一個(gè)機(jī)器周期檢測到中斷源口線為高電平,下一個(gè)機(jī)器周期檢測到低電平,即置位中斷標(biāo)志,請(qǐng)求中斷。這個(gè)原理很好理解。但應(yīng)用時(shí)需要特別注意的幾點(diǎn):電平觸發(fā)方式時(shí),中斷標(biāo)志寄存器不鎖存中斷請(qǐng)求信號(hào)。也就是說,單片機(jī)把每個(gè)機(jī)器周期的S5P2采樣到的外部中斷源口線的電平邏輯直接賦值到中斷標(biāo)志寄存器。
在MCU中都是以二進(jìn)制的形式進(jìn)行計(jì)算的.2.在編程時(shí),我們通常用到的有十進(jìn)制的數(shù)值形式和十六進(jìn)制的數(shù)值形式,如52,0xfe;3.數(shù)值的大小由數(shù)據(jù)的類型來決定。常用的有“unsignedint”和“unsignedchar”."unsignedchar"的范圍是"0-255",與單片機(jī)端口的8位的值(0xff)相對(duì)應(yīng)。"unsignedint"的范圍是"0-65535",與之對(duì)應(yīng)的是"0xffff"。

hmi——HumanMachineInterface。在工業(yè)領(lǐng)域,我們常將具有觸摸輸入功能的人機(jī)界面產(chǎn)品稱為“觸摸屏”。HMI用來連接可編程序控制器(plc)、變頻器、直流調(diào)速器、儀表等工業(yè)控制設(shè)備,利用顯示屏顯示,通過輸入單元(如觸摸屏、鍵盤、鼠標(biāo)等)寫入工作參數(shù)或輸入操作命令,實(shí)現(xiàn)人與機(jī)器信息交互的數(shù)字設(shè)備。那么,HMI就是觸摸屏嗎?其實(shí)不然,從嚴(yán)格意義上來說,兩者是有本質(zhì)上的區(qū)別的。因?yàn)椤坝|摸屏”僅是人機(jī)界面產(chǎn)品中可能用到的硬件部分,是一種替代鼠標(biāo)及鍵盤部分功能,安裝在顯示屏前端的輸入設(shè)備,而人機(jī)界面產(chǎn)品則是一種包含硬件和軟件的人機(jī)交互設(shè)備,由硬件和軟件兩部分組成。

中斷程序有條件返回指令CRETI(ConditionalRETurnfromInterrupt)在控制它的邏輯條件滿足時(shí)從中斷程序返回。編程軟件自動(dòng)地為各中斷程序添加無條件返回指令。中斷連接指令A(yù)TCH(AttachInterrupt)用來建立中斷事件(EVENT)和處理此事件的中斷程序(INT)之間的聯(lián)系。中斷事件由中斷事件號(hào)(見表1),中斷程序由中斷程序號(hào)。為某個(gè)中斷事件中斷程序后,該中斷事件被自動(dòng)地允許。
