[参考译文] MSP430F5659：等待外部时钟脉冲计数

我告诉你,我走错了轨道。

#include <msp430.h>

void main(void) {
    WDTCTL = WDTPW | WDTHOLD;   // Stop watchdog timer

    // Configure P6.4 as input
    P6DIR &= ~BIT4;             // Set P6.4 as input
    P6REN |= BIT4;              // Enable pull-up resistor
    P6OUT |= BIT4;              // Set pull-up resistor

    // Initialize variables
    unsigned int lastState = 0;
    unsigned int edgeCount = 0;

    // Main loop
    while (1) {
        // Read the current state of P6.4
        unsigned int currentState = (P6IN & BIT4) >> 4;

        // Check for rising edge
        if (currentState == 1 && lastState == 0) {
            edgeCount++;
        }

        // Update the last state
        lastState = currentState;

        // Check if 89 edges are detected
        if (edgeCount == 89) {
            // Take action when 89 edges are detected
            edgeCount = 0; // Reset the counter if needed
        }
    }
}

我想我自己已经解决了这个问题
