[Software Engineering] DIP DL : 0: 實驗二：指撥開關控制顯示一、實驗目的學習如何規劃8255工作於模式0（Mode 0），利用指撥開關（DIP S.W）作為基本輸入，以控制其輸出。二、實驗功能 1. 當電腦鍵盤按下“1”時，依指撥開關之設定顯示相對應之LEDs 2. 當電腦鍵盤按下“2”時，依指撥開關所設定中之最高位元，僅顯示相對應之LED。 3. 當電腦鍵盤按下“3”時，依DIP S.W所設定數值之和，以二進制編碼方式顯示於LEDs。三、基本原理本實驗乃利用8255完成基本的輸入與輸出功能。首先將8255規劃為模式0，且Port A為輸出，Port C為輸入。並將8個LEDs接至Port A，而將8位元指撥開關接至Port C。 1. 若電腦按鍵選擇“1”，依指撥開關的調設（ON為低電位，OFF則為高電位），藉由程式讀取Port C，直接將Port C讀取值送至Port A驅動LED顯示。 2. 若電腦按鍵選擇“2”，先將目前指撥開關設定值由Port C讀入，由最高位元逐一遞減判斷是否設定為ON。當發現第一個位元設定為ON，即僅驅動相對應於該位元位置之LED。 3. 若電腦按鍵選擇“3”，將目前指撥開關設定值由Port C讀入，並逐一累加所有設定為ON的指撥開關位置之相關數值。-Experiment 2: DIP switch control the display one purpose of the experiment to learn how to plan the 8255 work in the mode 0 (Mode 0), use DIP switch (DIP SW) as the basic input to control the output. Second, experimental features 1. When the computer keyboard by pressing the " 1" , according to the setting of DIP switch corresponds to the display LEDs 2. When the computer keyboard by pressing the " 2" when the DIP switch according to the highest bit set in only shows the corresponding LED. 3. When the computer keyboard by pressing " 3" , the value set by DIP SW s and, in binary encoding shown in the LEDs.
