19一、控制要求：通過Quartus=2\*ROMANII中SOPC工具，構(gòu)建開發(fā)板硬件,以及NIOSII8.0IDE編譯軟件程序，在實(shí)驗(yàn)箱（GX-SOC/SOPC-CIDE綜合創(chuàng)新開發(fā)試驗(yàn)平臺(tái)）控制7段數(shù)碼管，實(shí)現(xiàn)以下功能：按鍵1：控制7段數(shù)碼管從0~999按照一秒加1操作；按鍵2：控制7段數(shù)碼管從0~999按照一秒減1操作；按鍵3：控制7段數(shù)碼管加1或者減1操作停止。二、設(shè)計(jì)思路：添加實(shí)驗(yàn)范例cide_c2中的完整硬件，對(duì)本次實(shí)驗(yàn)需要使用到的硬件進(jìn)行剪裁，僅留下必須的最小硬件系統(tǒng)。軟件方面，使用到i2c總線讀取、ch452芯片的7段數(shù)碼管。程序需要完成按鍵的判斷，實(shí)現(xiàn)該按鍵對(duì)應(yīng)的操作?？刂瞥绦蚴褂肅語(yǔ)言編程。三、設(shè)計(jì)目的：學(xué)習(xí)應(yīng)用i2c總線的讀寫方式；運(yùn)用ch452芯片的數(shù)碼管顯示功能。四、實(shí)驗(yàn)步驟：1、打開實(shí)驗(yàn)完整硬件后，使用SOPC軟件進(jìn)行硬件剪裁：（剪裁前）（剪裁后）2、剪裁后對(duì)CPU存儲(chǔ)重新配置：3、重新編輯symbol以及管腳分配：管腳分配，可以使用文本方式修改，在記錄管腳分配的QSF文件中，保留以下文本即可：set_location_assignmentPIN_L1-toclk_sysset_location_assignmentPIN_L2-toresetset_location_assignmentPIN_R5-tosdram_addr[0]set_location_assignmentPIN_U2-tosdram_addr[1]set_location_assignmentPIN_U1-tosdram_addr[2]set_location_assignmentPIN_T2-tosdram_addr[3]set_location_assignmentPIN_T1-tosdram_addr[4]set_location_assignmentPIN_R2-tosdram_addr[5]set_location_assignmentPIN_R1-tosdram_addr[6]set_location_assignmentPIN_P6-tosdram_addr[7]set_location_assignmentPIN_P5-tosdram_addr[8]set_location_assignmentPIN_P3-tosdram_addr[9]set_location_assignmentPIN_R6-tosdram_addr[10]set_location_assignmentPIN_N4-tosdram_addr[11]set_location_assignmentPIN_V2-tosdram_ba[0]set_location_assignmentPIN_V1-tosdram_ba[1]set_location_assignmentPIN_U3-tosdram_nCASset_location_assignmentPIN_N6-tosdram_CKEset_location_assignmentPIN_T6-tosdram_nCSset_location_assignmentPIN_V4-tosdram_data[0]set_location_assignmentPIN_W5-tosdram_data[1]set_location_assignmentPIN_Y4-tosdram_data[2]set_location_assignmentPIN_Y3-tosdram_data[3]set_location_assignmentPIN_W4-tosdram_data[4]set_location_assignmentPIN_W3-tosdram_data[5]set_location_assignmentPIN_Y2-tosdram_data[6]set_location_assignmentPIN_Y1-tosdram_data[7]set_location_assignmentPIN_P1-tosdram_data[8]set_location_assignmentPIN_N2-tosdram_data[9]set_location_assignmentPIN_N1-tosdram_data[10]set_location_assignmentPIN_M6-tosdram_data[11]set_location_assignmentPIN_M5-tosdram_data[12]set_location_assignmentPIN_J2-tosdram_data[13]set_location_assignmentPIN_J1-tosdram_data[14]set_location_assignmentPIN_J4-tosdram_data[15]set_location_assignmentPIN_W2-tosdram_DQM[0]set_location_assignmentPIN_P2-tosdram_DQM[1]set_location_assignmentPIN_T3-tosdram_nRASset_location_assignmentPIN_W1-tosdram_nWEset_location_assignmentPIN_C14-tosram_nCS1set_location_assignmentPIN_U4-tosdram_clkset_location_assignmentPIN_Y20-tobutton_pio[7]set_location_assignmentPIN_Y21-tobutton_pio[6]set_location_assignmentPIN_Y22-tobutton_pio[5]set_location_assignmentPIN_W22-tobutton_pio[4]set_location_assignmentPIN_N21-tobutton_pio[3]set_location_assignmentPIN_R18-tobutton_pio[2]set_location_assignmentPIN_AB17-tobutton_pio[1]set_location_assignmentPIN_U18-tobutton_pio[0]set_location_assignmentPIN_AA14-tokey_INT_nset_location_assignmentPIN_Y18-tosclset_location_assignmentPIN_AA19-tosdaset_location_assignmentPIN_AB13-toseg_key_sclset_location_assignmentPIN_AA12-toseg_key_sda4、完全編譯后，通過JTAG端口，燒錄到試驗(yàn)箱中：5、NIOSII8.0IDE中進(jìn)行軟件編譯：建立工程，把所有使用到的程序添加到工程文件下，進(jìn)行編譯6、編譯完成后，選擇RUNASniosⅡhardware：五、實(shí)驗(yàn)結(jié)果（實(shí)驗(yàn)箱截圖）：六、心得體會(huì)。這門課程在開始的時(shí)候毫無頭緒，不知從何下手，然后經(jīng)過慢慢學(xué)習(xí)了解，才開始對(duì)SOPC稍微有了整體概念、思路。通過這學(xué)期的學(xué)期，有了很到收獲：首先，通過學(xué)習(xí)，使自己對(duì)課本上的知識(shí)可以應(yīng)用于實(shí)際，使得理論與實(shí)際相結(jié)合，加深自己對(duì)課本上的知識(shí)更好的理解，同事事實(shí)也鍛煉了個(gè)人動(dòng)手能力,對(duì)quartusⅡniosⅡ等仿真軟件操作達(dá)到學(xué)以致用。在設(shè)計(jì)中遇到了很多問題，在張老師的辛勤指導(dǎo)下，得以解決。最后對(duì)自己有過幫助的同學(xué)和老師表示感謝！七、程序：1、主程序：seven_seg.c#include"system.h"#include"alt_types.h"#include"altera_avalon_pio_regs.h"#include"define.h"#include"CH452_I2C.h"#include"key.h"#include"priv/alt_busy_sleep.h"#include"sys/alt_irq.h"#include"key.h"#defineADDKEY1//#defineDECREASEKEY2//#defineSTOPKEY3//intmain(void){alt_u8KeyVlaue;inti;KeyPIOInit();KeyIntEnable();CH452_Write(CH452_SYSON2);//兩線制方式，如果SDA用做按鍵中斷輸出，那么命令應(yīng)該為(0x04,0x23)CH452_Write(CH452_BCD);//BCD譯碼,8個(gè)數(shù)碼管while(1){KeyVlaue=GetKeyValue();switch(KeyVlaue){caseADD:{while(1){KeyVlaue=GetKeyValue();if(KeyVlaue==DECREASE)break;elseif(KeyVlaue==STOP)break;else{if(i>999)i=0;elsei+=1;}alt_busy_sleep(100000);CH452_Write(CH452_DIG2|i/100);CH452_Write(CH452_DIG1|i/10%10);CH452_Write(CH452_DIG0|i%10);}break;}caseDECREASE:{while(1){KeyVlaue=GetKeyValue();if(KeyVlaue==ADD)break;elseif(KeyVlaue==STOP)break;else{if(i<=0)i=999;elsei-=1;}alt_busy_sleep(100000);CH452_Write(CH452_DIG2|i/100);CH452_Write(CH452_DIG1|i/10%10);CH452_Write(CH452_DIG0|i%10);}break;}caseSTOP:{while(1){KeyVlaue=GetKeyValue();if(KeyVlaue==ADD)break;elseif(KeyVlaue==DECREASE)break;elsei=i;alt_busy_sleep(100000);CH452_Write(CH452_DIG2|i/100);CH452_Write(CH452_DIG1|i/10%10);CH452_Write(CH452_DIG0|i%10);}break;}}}}2、CH452_I2C.h#include"system.h"#include"altera_avalon_pio_regs.h"#include"alt_types.h"#include"priv/alt_busy_sleep.h"#include<stdio.h>#include"sys/alt_irq.h"#include"define.h"voidCH452_
