首先将行线P1.0-P1.3作为输入线，列线P1.4-P1.7作为输出线，并且输出线输出全为低电平，读行线状态，那么行线中电平为低的是按键所在的行。然后将列线作为输入线，行线作为输出线，并将输出线输出为低电平，读列线状态，那么列线是电平为低的是按键所在的列。综合上述两步结果，确定按键所在的行和列，从而识别出所按下的键。

假设10号键被按下，在第一步P1.3-P1.0全为低电平时，读P1.4-P1.7的值，那么P1.5为低电平；在第二步P1.4-P1.7输出全为低电平时，读P1.3-P1.0时，P1.2为低电平。由此可判断第3行第2列有键被按下，此键就是K10键。键盘等其他外部设备与CPU之间如何协调工作？答：cpu通过I/O接口和外部设备进行数据交换。cpu通过接口对外设进行控制的方式有以下几种：程序查询方式、中断处理方式、DMA传送方式。在实验报告中对键盘中断效劳程序进行逐行注释，理解计算机是如何接收键盘输入的。答：voidGPIO_PORT_D_ISR(void){unsignedcharucKey;//定义一个unsignedchar类型的变量ucKeyunsignedlongulStatus;//定义一个unsignedlong类型的变量ulStatusulStatus=GPIOPinIntStatus(GPIO_PORTD_BASE,true);//读取中断状态GPIOPinIntClear(GPIO_PORTD_BASE,ulStatus);//清空读取到的中断if(ulStatus&GPIO_PIN_7)//如果GPIO_PIN_7中断状态有效{ucKey=GPIOPinRead(GPIO_PORTC_BASE,GPIO_PIN_4);//读取管脚ucKey=ucKey>>1;//ucKey右移一位ucValue=ucValue+ucKey;//ucValue+1ucValue=ucValue<<1;//ucValue左移一位i++;if(i==4)//如果发生四次中断{i=0;//i置0Event_Key=1;//Event_Key置一，代表按键信息已传给cpuoledkey[1]='\0';给oledKey[1]赋值\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右移四位减10加A}}}根据实验思考，如果有两个不同的中断需要响应时，应该如何设计程序？答：while(1){if(Event_key)//中断1发生的标志{Event_key=0;….…}if(Event)//中断2发生的标志{Event=0;……}}按下几个键后屏幕中出现多个字符怎么办？如何只显示一个？答：发生一次按键中断后调用一次函数RIT128x96x4Clear();。〔6〕因为本次实验需要响应两个中断，需要对主函数的死循环做以下改动。while(1){if(Event_key){Event_key=0;….…}if(Event){Event=0;……}}思考：这样设计的目的和作用是什么？要是系统需要响应4个不同的中断又如何设计？答：目的是使各个中断的处理不受影响。如果需要响应4个不同的中断那么需要定义四个全局变量〔值为0或1〕来标记每个中断。例如如下：while(1){if(Event1){Event1=0;….…}if(Event2){Event2=0;……}if(Event3){Event3=0;……}if(Event4){Event4=0;……}}实验目的和效果实验目的：〔1〕了解键盘工作原理和使用方法〔2〕深入学习、理解、掌握中断使用方法实验效果：三、实验内容和步骤实验内容：默认在在OLED屏幕上分行显示自己的学号、姓名，如“2023011001〞、“zhangsan〞。思路：RIT128x96x4StringDraw直接显示。按下键盘的任意键，在OLED屏幕正中显示该键字符，如“0〞、“A〞等。思路：通过oledkey得到键盘的值，利用RIT128x96x4StringDraw显示在屏幕上。按下键盘的偶数键时，在OLED屏幕上显示“NowShowChar！〞提示信息，并在OLED屏幕上显示实验一的字符，并根据按下的键值，确定字符的位置，按“0〞、“2〞、“4〞、“6〞、“8〞、“A〞、“C〞、“E〞分别在最左端，距左端1/8屏幕宽度处、距左端2/8屏幕宽度处、距左端3/8屏幕宽度处、距左端1/2屏幕宽度处、距右端3/8屏幕宽度处、距右端2/8屏幕宽度处、距右端1/8屏幕宽度处、最右端显示。要保证字符可以全部显示。思路：通过switch语句进行判断，当键盘值为上述字符时调用Draw_Char_F(ulx)在相应位置显示字符图形。按下键盘的奇数键时，在OLED屏幕上显示“NowResetSpeed！〞提示信息，在OLED屏幕上显示实验二的效果，即根据自己分配的阈值和移动路线上对字符进行移动，并根据按下的键值，确定频率的快慢，按“1〞、“3〞、“5〞、“7〞、“9〞、“B〞、“D〞、“F〞由慢到快〔速度可以逐个递增2倍或5倍〕。思路：通过switch语句进行判断，当键盘值为上述字符时调用Reset_Counter_Speed(x)设置字符的不同移动速度。根据自己的想法，选用一个按键，在OLED屏幕上显示与上面不同的效果。思路：一朵花从花盆中长出花茎、叶子、花朵。通过不同的按键长出花的不同局部。实验步骤：〔一〕Keil开发环境中对工程Project配置见实验一〔一〕步骤〔二〕嵌入式C程序开发〔1〕加载必要程序本次实验提供了几个源程序rit128x96x4.h，rit128x96x4.c，startup.s，都压在work3_code.zip中，与实验一〔二〕〔1〕步骤类似。〔2〕新建主函数程序，并加载到工程中新建一个文件，保存为main.c，把main.c也加载到工程中，与实验一〔二〕〔2〕步骤类似。本次实验需要增加以下头文件#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"本次实验显示的内容实验〔二〕已完成，故可在实验〔二〕根底上进一步开发。〔3〕利用中断，接收键盘输入〔3〕--〔1〕在主函数中开启键盘中断，例如如下：/*使能外设GPIO*/SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOC);SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOD);/*设置GPIO为输入*/GPIOPinTypeGPIOInput(GPIO_PORTD_BASE,GPIO_PIN_7);GPIOPinTypeGPIOInput(GPIO_PORTC_BASE,GPIO_PIN_4);/*使能中断*/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用于传输按下的键值，GPIO_PORTD用于向CPU发起中断请求。〔3〕--〔2〕设置全局变量oledkey用于保存键盘输入的按键charoledkey[2];〔3〕--〔3〕设计实现并注册键盘中断处理函数键盘每次按键都会触发四次中断，中断信号源为GPIOPortD，修改startup.s中GPIOPortD项对应的中断效劳处理函数，与实验〔二〕设置中断流程类似，这里不再重复。键盘中断处理函数例如如下：inti=0;//i定义为全局变量，因为只有1根线GPIO_PIN_4与CPU相联，所以一个按键〔16种，4bit表示〕需要四次中断才能传给CPU。unsignedcharucValue=0x00;//ucValue定义为全局变量，该值存储输入的按键值的中间结果。/*中断效劳函数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';}}}该程序就可以根据键盘中断信号获取键盘输入值，并通过并行转串行转换，将该值存放在oledkey[0]中。〔4〕修改主函数，实现本次实验要求的功能本次实验通过不同键盘控制不同显示，但显示内容实验〔二〕都已完成，故可在实验〔二〕根底上继续深入开发，完成实验〔三〕。〔4〕--〔1〕通过一个全局变量值控制按键后的处理在主函数的while死循环中，应该添加对按键后的处理程序，方法类似于实验〔二〕中对SysTick中断的处理，即设置一个全局变量Event_key，通过在中断效劳程序中设其值为1，主程序死循环中设其值为0来实现。思考一下，应该在中断效劳程序voidGPIO_PORT_D_ISR(void)中的哪个位置设置Event_key为1。提示：一个按键发起四次中断，通过全局变量i计数，到第四次时才表示接收完毕，在此处设置Event_key为1。〔4〕--〔2〕主函数死循环流程因为本次实验需要响应两个中断，需要对主函数的死循环做以下改动。while(1){if(Event_key){Event_key=0;….…}if(Event){Event=0;……}}思考：实验问题6：这样设计的目的和作用是什么？要是系统需要响应4个不同的中断又如何设计？〔4〕--〔3〕发生一次键盘按键后，中断效劳程序完成后，全局变量oledkey[0]中保存的即是输入字符，根据该字符值和实验要求，设计程序。例如如下：switch(oledkey[0]){case'0':Draw_Char_H(0);Flag=0;break;case'1':Reset_Counter_Speed(1);break;case'2':Draw_Char_H(25);break;case'3':Reset_Counter_Speed(2);break;default:break;}〔4〕--〔4〕偶数时，在不同位置显示字符Draw_Char_H即是画出字符，本例画的是H字符，因为根据输入字符来确定显示位置，因此位置信息作为该函数参数传入，根据要求设计实现该函数。〔4〕--〔5〕奇数时，设置计数器计数频率Reset_Counter_Speed函数完成重新设置计数器的计数频率，其程序流程为关中断---重设中断周期---开中断。例如如下：voidReset_Counter_Speed(){SysTickIntDisable();SysTickDisable();SysTickPeriodSet(SysCtlClockGet()/x);//x为输入的参数，控制计数频率，值越大频率越快SysTickEnable();SysTickIntEnable();}〔4〕--〔6〕完成实验根据实验要求，补齐switch语句。〔5〕编译、连接，生成可执行程序文件〔编译〕〔链接〕〔6〕反复〔3〕--〔5〕步骤，直到完成如果中间出现错误，修改代码，一直到无错，生成最后程序。〔三〕硬件连接见实验〔一〕〔三〕步骤。〔四〕联调见实验〔一〕〔四〕步骤。实验代码：〔实验代码过长，放在实验报告最后〕实验总结与收获附：实验代码#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"intEvent=0;intEvent_Key=0;intcount1=0;charoledkey[2];inti=0;intz=56;unsignedcharucValue=0x00;unsignedcharbuf01[]=//开放的花{0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00};unsignedcharbuf02[]={0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00};unsignedcharbuf03[]={0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00};unsignedcharbuf04[]={0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0xff,0xff,0xff,0xff,0x00,0x00,0x00,0x00,0xff,0xff,0xff,0xff,0x00,0x00,0x00,0x00,0xff,0xff,0xff,0xff,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff};unsignedcharbuf05[]={0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0xff,0xff,0xff,0xff,0x00,0x00,0x00,0x00,0xff,0xff,0xff,0xff,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff};unsignedcharbuf06[]={0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff};unsignedcharbuf07[]={0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff};unsignedcharbuf08[]={0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff};unsignedcharbuf09[]={0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff};unsignedcharbuf010[]={0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff};unsignedcharbuf011[]={0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff};unsignedcharbuf012[]={0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff};unsignedcharbuf013[]={0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff};unsignedcharbuf015[]={0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,};unsignedcharbuf014[]={0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff};unsignedcharbuf016[]={0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00};unsignedcharbuf017[]={0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xff,0xff,0x00,0x00,0x00,0x0
