我正在使用 MPLAB C18 编译器为 PIC18F2550 编写用于控制记忆游戏的 c 代码。用户将通过按下相应的按钮重复一系列闪烁的 LED。有点像老式的西蒙游戏,但序列只发生了一次。
到目前为止,我一直在苦苦挣扎,我只设法打开了一些 LED,但这些按钮只会关闭 LED 片刻,然后它们会再次亮起。
到目前为止,这是我的代码:
#include <stdio.h>
#include <stdlib.h>
#include <p18f2550.h>
#include <delays.h>
//#pragma config WDT = OFF //Disable watchdog timer
// LED Configuration
#define LED_PIN_0 LATAbits.LATA0 //RA0
#define LED_PIN_1 LATAbits.LATA1 //RA1
#define LED_PIN_2 LATAbits.LATA2 //RA2
#define LED_PIN_3 LATAbits.LATA3 //RA3
#define LED_PIN_4 LATAbits.LATA4 //RA4
#define LED_PIN_5 LATAbits.LATA5 //RA5
#define LED_PIN_6 LATAbits.LATA6 //RA6
// Push Button Configuration
#define PUSH_BUTTON_0 PORTBbits.RB0 //RB0
#define PUSH_BUTTON_1 PORTBbits.RB1 //RB1
#define PUSH_BUTTON_2 PORTBbits.RB2 //RB2
#define PUSH_BUTTON_3 PORTBbits.RB3 //RB3
#define PUSH_BUTTON_4 PORTBbits.RB4 //RB4
#define PUSH_BUTTON_5 PORTBbits.RB5 //RB5
#define PUSH_BUTTON_6 PORTBbits.RB6 //RB6
// Global Variables
int led_array[7] ; // array storing the pin outs
int button_array[7] ;
void main()
{
int i;
ADCON1 = 0b11111111;
TRISA = 0; // sets the LED pins to output
TRISB = 1; // sets pushbutton pins to input
PORTA = 0;
PORTB = 0;
//sequence
led_array[0] = 1 ;
led_array[1] = 0 ;
led_array[2] = 1 ;
led_array[3] = 0 ;
led_array[4] = 1 ;
led_array[5] = 1 ;
led_array[6] = 0 ;
// Configure the LEDs
LED_PIN_0 = led_array[0] ;
LED_PIN_1 = led_array[1] ;
LED_PIN_2 = led_array[2] ;
LED_PIN_3 = led_array[3] ;
LED_PIN_4 = led_array[4] ;
LED_PIN_5 = led_array[5] ;
LED_PIN_6 = led_array[6] ;
// Configure the push button array
PUSH_BUTTON_0 = button_array[0] ;
PUSH_BUTTON_1 = button_array[1] ;
PUSH_BUTTON_2 = button_array[2] ;
PUSH_BUTTON_3 = button_array[3] ;
PUSH_BUTTON_4 = button_array[4] ;
PUSH_BUTTON_5 = button_array[5] ;
PUSH_BUTTON_6 = button_array[6] ;
if ( PUSH_BUTTON_0 == 1 )
{
led_array[0] = 0;
}
if ( PUSH_BUTTON_1 == 1 )
{
led_array[1] = 1;
}
if ( PUSH_BUTTON_2 == 1 )
{
led_array[2] = 0;
}
if ( PUSH_BUTTON_3 == 1 )
{
led_array[3] = 1;
}
if ( PUSH_BUTTON_4 == 1 )
{
led_array[4] = 0;
}
if ( PUSH_BUTTON_5 == 1 )
{
led_array[5] = 0;
}
if ( PUSH_BUTTON_6 == 1 )
{
led_array[6] = 1;
}
}
任何帮助是极大的赞赏!!
