使用c语言对msp430写一个流水灯程序，一共有四个灯引脚分别是p10.6，篇。7

在MSP430微控制器上编写一个包含四个灯的流水灯程序，可以利用它的P1.6和P1.7端口，我们可以使用定时器和位操作来实现。下面是一个简单例子：

#include "msp430.h" // Include MSP430-specific headers
#include "driverlib/timer.h"

// Define constants for P1.6 and P1.7 pins
#define LED1_PIN BIT6
#define LED2_PIN BIT7
#define LEDS_ON_PORT P1OUT
#define LEDS_OFF_PORT P1IN

void set_led(int led_num, bool state) {
    if (led_num == 1) {
        if (state) {
            LEDS_ON_PORT |= LED1_PIN;
        } else {
            LEDS_OFF_PORT |= LED1_PIN;
        }
    } else if (led_num == 2) {
        if (state) {
            LEDS_ON_PORT |= LED2_PIN;
        } else {
            LEDS_OFF_PORT |= LED2_PIN;
        }
    }
}

void blink_all_lights(int on_time_ms, int off_time_ms) {
    TimerAConfigure(TimerA_BASE, TIMER_A_UP_MODE, (FREQUENCY / 100), FALSE); // Configure timer A for up mode
    TimerASetTimer(ACTIVE偏低16位计数, (on_time_ms * (FREQUENCY / 100)) - 1); // Calculate initial timer value for desired on time

    while (!TimerATimerExpired()) { // Loop until timer expires
        TimerAStop(TimerA_BASE); // Stop the timer
        LEDS_ON_PORT ^= LEDS_OFF_PORT; // Toggle all LEDs
        TimerAReset(TimerA_BASE); // Reset the timer to start counting again
    }

    TimerAStart(TimerA_BASE); // Restart the timer for the off period
    TimerASetTimer(ACTIVE偏低16位计数, (off_time_ms * (FREQUENCY / 100)) - 1);

    // Repeat this cycle indefinitely
}

int main(void) {
    WDTCTL = WDTPW + WDTHOLD; // Disable watchdog timer
    P1SEL |= (LED1_PIN | LED2_PIN); // Configure pins as outputs

    while (1) {
        blink_all_lights(500, 500); // Blink lights on and off every second
    }
    return 0;
}
