首先將行線P1.0-P1.3作為輸入線，列線P1.4-P1.7作為輸出線，并且輸出線輸出全為低電平，讀行線狀態(tài)，那么行線中電平為低的是按鍵所在的行。然后將列線作為輸入線，行線作為輸出線，并將輸出線輸出為低電平，讀列線狀態(tài)，那么列線是電平為低的是按鍵所在的列。綜合上述兩步結(jié)果，確定按鍵所在的行和列，從而識別出所按下的鍵。

假設(shè)10號鍵被按下，在第一步P1.3-P1.0全為低電平時，讀P1.4-P1.7的值，那么P1.5為低電平；在第二步P1.4-P1.7輸出全為低電平時，讀P1.3-P1.0時，P1.2為低電平。由此可判斷第3行第2列有鍵被按下，此鍵就是K10鍵。鍵盤等其他外部設(shè)備與CPU之間如何協(xié)調(diào)工作？答：cpu通過I/O接口和外部設(shè)備進(jìn)行數(shù)據(jù)交換。cpu通過接口對外設(shè)進(jìn)行控制的方式有以下幾種：程序查詢方式、中斷處理方式、DMA傳送方式。在實(shí)驗(yàn)報告中對鍵盤中斷效勞程序進(jìn)行逐行注釋，理解計算機(jī)是如何接收鍵盤輸入的。答：voidGPIO_PORT_D_ISR(void){unsignedcharucKey;//定義一個unsignedchar類型的變量ucKeyunsignedlongulStatus;//定義一個unsignedlong類型的變量ulStatusulStatus=GPIOPinIntStatus(GPIO_PORTD_BASE,true);//讀取中斷狀態(tài)GPIOPinIntClear(GPIO_PORTD_BASE,ulStatus);//清空讀取到的中斷if(ulStatus&GPIO_PIN_7)//如果GPIO_PIN_7中斷狀態(tài)有效{ucKey=GPIOPinRead(GPIO_PORTC_BASE,GPIO_PIN_4);//讀取管腳ucKey=ucKey>>1;//ucKey右移一位ucValue=ucValue+ucKey;//ucValue+1ucValue=ucValue<<1;//ucValue左移一位i++;if(i==4)//如果發(fā)生四次中斷{i=0;//i置0Event_Key=1;//Event_Key置一，代表按鍵信息已傳給cpuoledkey[1]='\0';給oledKey[1]賦值\0if((ucValue>>4)<10)//如果ucValue右移四位后小于10oledkey[0]=(ucValue>>4)+48;//那么oledkey[0]右移四位后加48elseoledkey[0]=(ucValue>>4)-10+'A';//否那么ucValue右移四位減10加A}}}根據(jù)實(shí)驗(yàn)思考，如果有兩個不同的中斷需要響應(yīng)時，應(yīng)該如何設(shè)計程序？答：while(1){if(Event_key)//中斷1發(fā)生的標(biāo)志{Event_key=0;….…}if(Event)//中斷2發(fā)生的標(biāo)志{Event=0;……}}按下幾個鍵后屏幕中出現(xiàn)多個字符怎么辦？如何只顯示一個？答：發(fā)生一次按鍵中斷后調(diào)用一次函數(shù)RIT128x96x4Clear();?！?〕因?yàn)楸敬螌?shí)驗(yàn)需要響應(yīng)兩個中斷，需要對主函數(shù)的死循環(huán)做以下改動。while(1){if(Event_key){Event_key=0;….…}if(Event){Event=0;……}}思考：這樣設(shè)計的目的和作用是什么？要是系統(tǒng)需要響應(yīng)4個不同的中斷又如何設(shè)計？答：目的是使各個中斷的處理不受影響。如果需要響應(yīng)4個不同的中斷那么需要定義四個全局變量〔值為0或1〕來標(biāo)記每個中斷。例如如下：while(1){if(Event1){Event1=0;….…}if(Event2){Event2=0;……}if(Event3){Event3=0;……}if(Event4){Event4=0;……}}實(shí)驗(yàn)?zāi)康暮托Ч麑?shí)驗(yàn)?zāi)康模骸?〕了解鍵盤工作原理和使用方法〔2〕深入學(xué)習(xí)、理解、掌握中斷使用方法實(shí)驗(yàn)效果：三、實(shí)驗(yàn)內(nèi)容和步驟實(shí)驗(yàn)內(nèi)容：默認(rèn)在在OLED屏幕上分行顯示自己的學(xué)號、姓名，如“2023011001〞、“zhangsan〞。思路：RIT128x96x4StringDraw直接顯示。按下鍵盤的任意鍵，在OLED屏幕正中顯示該鍵字符，如“0〞、“A〞等。思路：通過oledkey得到鍵盤的值，利用RIT128x96x4StringDraw顯示在屏幕上。按下鍵盤的偶數(shù)鍵時，在OLED屏幕上顯示“NowShowChar！〞提示信息，并在OLED屏幕上顯示實(shí)驗(yàn)一的字符，并根據(jù)按下的鍵值，確定字符的位置，按“0〞、“2〞、“4〞、“6〞、“8〞、“A〞、“C〞、“E〞分別在最左端，距左端1/8屏幕寬度處、距左端2/8屏幕寬度處、距左端3/8屏幕寬度處、距左端1/2屏幕寬度處、距右端3/8屏幕寬度處、距右端2/8屏幕寬度處、距右端1/8屏幕寬度處、最右端顯示。要保證字符可以全部顯示。思路：通過switch語句進(jìn)行判斷，當(dāng)鍵盤值為上述字符時調(diào)用Draw_Char_F(ulx)在相應(yīng)位置顯示字符圖形。按下鍵盤的奇數(shù)鍵時，在OLED屏幕上顯示“NowResetSpeed！〞提示信息，在OLED屏幕上顯示實(shí)驗(yàn)二的效果，即根據(jù)自己分配的閾值和移動路線上對字符進(jìn)行移動，并根據(jù)按下的鍵值，確定頻率的快慢，按“1〞、“3〞、“5〞、“7〞、“9〞、“B〞、“D〞、“F〞由慢到快〔速度可以逐個遞增2倍或5倍〕。思路：通過switch語句進(jìn)行判斷，當(dāng)鍵盤值為上述字符時調(diào)用Reset_Counter_Speed(x)設(shè)置字符的不同移動速度。根據(jù)自己的想法，選用一個按鍵，在OLED屏幕上顯示與上面不同的效果。思路：一朵花從花盆中長出花莖、葉子、花朵。通過不同的按鍵長出花的不同局部。實(shí)驗(yàn)步驟：〔一〕Keil開發(fā)環(huán)境中對工程Project配置見實(shí)驗(yàn)一〔一〕步驟〔二〕嵌入式C程序開發(fā)〔1〕加載必要程序本次實(shí)驗(yàn)提供了幾個源程序rit128x96x4.h，rit128x96x4.c，startup.s，都壓在work3_code.zip中，與實(shí)驗(yàn)一〔二〕〔1〕步驟類似?！?〕新建主函數(shù)程序，并加載到工程中新建一個文件，保存為main.c，把main.c也加載到工程中，與實(shí)驗(yàn)一〔二〕〔2〕步驟類似。本次實(shí)驗(yàn)需要增加以下頭文件#include<stdio.h>#include<LM3Sxxxx.H>#include<hw_ints.h>#include<hw_memmap.h>#include<hw_types.h>#include<gpio.h>#include<interrupt.h>#include<sysctl.h>#include"rit128x96x4.h"本次實(shí)驗(yàn)顯示的內(nèi)容實(shí)驗(yàn)〔二〕已完成，故可在實(shí)驗(yàn)〔二〕根底上進(jìn)一步開發(fā)?！?〕利用中斷，接收鍵盤輸入〔3〕--〔1〕在主函數(shù)中開啟鍵盤中斷，例如如下：/*使能外設(shè)GPIO*/SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOC);SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOD);/*設(shè)置GPIO為輸入*/GPIOPinTypeGPIOInput(GPIO_PORTD_BASE,GPIO_PIN_7);GPIOPinTypeGPIOInput(GPIO_PORTC_BASE,GPIO_PIN_4);/*使能中斷*/IntEnable(INT_GPIOD);IntMasterEnable();GPIOPinIntEnable(GPIO_PORTD_BASE,GPIO_PIN_7);GPIOIntTypeSet(GPIO_PORTD_BASE,GPIO_PIN_7,GPIO_RISING_EDGE);注意：其中，GPIO_PORTC用于傳輸按下的鍵值，GPIO_PORTD用于向CPU發(fā)起中斷請求?！?〕--〔2〕設(shè)置全局變量oledkey用于保存鍵盤輸入的按鍵charoledkey[2];〔3〕--〔3〕設(shè)計實(shí)現(xiàn)并注冊鍵盤中斷處理函數(shù)鍵盤每次按鍵都會觸發(fā)四次中斷，中斷信號源為GPIOPortD，修改startup.s中GPIOPortD項(xiàng)對應(yīng)的中斷效勞處理函數(shù)，與實(shí)驗(yàn)〔二〕設(shè)置中斷流程類似，這里不再重復(fù)。鍵盤中斷處理函數(shù)例如如下：inti=0;//i定義為全局變量，因?yàn)橹挥?根線GPIO_PIN_4與CPU相聯(lián)，所以一個按鍵〔16種，4bit表示〕需要四次中斷才能傳給CPU。unsignedcharucValue=0x00;//ucValue定義為全局變量，該值存儲輸入的按鍵值的中間結(jié)果。/*中斷效勞函數(shù)ISR*/voidGPIO_PORT_D_ISR(void){unsignedcharucKey;unsignedlongulStatus;ulStatus=GPIOPinIntStatus(GPIO_PORTD_BASE,true);GPIOPinIntClear(GPIO_PORTD_BASE,ulStatus);if(ulStatus&GPIO_PIN_7){ucKey=GPIOPinRead(GPIO_PORTC_BASE,GPIO_PIN_4);ucKey=ucKey>>1;ucValue=ucValue+ucKey;ucValue=ucValue<<1;i++;if(i==4){i=0;oledkey[1]='\0';if((ucValue>>4)<10)oledkey[0]=(ucValue>>4)+48;elseoledkey[0]=(ucValue>>4)-10+'A';}}}該程序就可以根據(jù)鍵盤中斷信號獲取鍵盤輸入值，并通過并行轉(zhuǎn)串行轉(zhuǎn)換，將該值存放在oledkey[0]中。〔4〕修改主函數(shù)，實(shí)現(xiàn)本次實(shí)驗(yàn)要求的功能本次實(shí)驗(yàn)通過不同鍵盤控制不同顯示，但顯示內(nèi)容實(shí)驗(yàn)〔二〕都已完成，故可在實(shí)驗(yàn)〔二〕根底上繼續(xù)深入開發(fā)，完成實(shí)驗(yàn)〔三〕。〔4〕--〔1〕通過一個全局變量值控制按鍵后的處理在主函數(shù)的while死循環(huán)中，應(yīng)該添加對按鍵后的處理程序，方法類似于實(shí)驗(yàn)〔二〕中對SysTick中斷的處理，即設(shè)置一個全局變量Event_key，通過在中斷效勞程序中設(shè)其值為1，主程序死循環(huán)中設(shè)其值為0來實(shí)現(xiàn)。思考一下，應(yīng)該在中斷效勞程序voidGPIO_PORT_D_ISR(void)中的哪個位置設(shè)置Event_key為1。提示：一個按鍵發(fā)起四次中斷，通過全局變量i計數(shù)，到第四次時才表示接收完畢，在此處設(shè)置Event_key為1?！?〕--〔2〕主函數(shù)死循環(huán)流程因?y
