DSP综合实验4.doc

实验四综合实验一、实验目的：1、熟悉CCS编程的整体结构；2、熟悉存储器的扩展；3、熟悉串口通信。二、实验内容：对给出的测试程序进行修改，以达到预期的要求。三、实验程序说明：1、所有子程序的函数都在init.c文件中测试程序的每一部分都做成了函数，只要调用子函数就能执行相应的程序，子程序包括：I/O口、步进电机、直流电机、蜂鸣器等。2、chkmem.asm文件为存储器测试程序的汇编文件，包括扩展的RAM和ROM，地址分别为0x8000、0x18000、0x28000，编写了完整的读写程序；3、还有一部分就的串口通信程序，主要是完成和51单片机的通信，因51单片机控制着键盘、8个数码管和液晶显示，和其通信主要是为了控制输入输出。四、实验内容：1、修改蜂鸣器测试部分程序，当测试蜂鸣器时使其响5声，若不响查看JP14是否为弹起状态，在init.c文件中的sp()中修改；2、修改存储器测试程序，使其读写次数改为32，在chkmem.asm中修改；3、修改液晶显示程序，修改结果为：程序运行后按2进入第二屏，修改这一屏的显示，修改后为：1.存储器，2. 步进电机，3.直流电机，4.交通灯，5. 喇叭，按相应的键进入相应的程序中执行；4、修改交通灯测试程序，使其符合生活中的十字路口交通灯；在init.c文件中的traffic_led()中修改，要巧妙运用Led_Traffic18、Led_Delay18，两个数组，只要修改这两个数组的数据就能实现结果。实验程序段：#include #include #include #include #define IMR_ADDR 0int s;char *b;#define UART_COUNTER 0x62#define KEYIN_COUNTER 0X61#define LCD_SIZE 23#define KEY_SIZE 6#define LED_SIZE 14ioport unsigned port8000; /* for CTRL word */ioport unsigned porte000; /* for DC MOTOR run */ioport unsigned portc000; /* for LEDs show */ioport unsigned portf000; /* for STEPMOTOR */unsigned int CtrlWord=0;char LCD_BufferLCD_SIZE= 0x55,0x66 ; /* LCD SHOWs buffer */char KEY_BufferKEY_SIZE; /* KEY INPUTs buffer */int Iskey=0; /* if Iskey!=0,then have KEY in */ /* its high 8 bits are key code !
