将结果从寄存器保存到数组 [1000] 中，无需用户每次输入

问题描述

这是我正在使用的示例代码，

#include <msp430.h>

int main(void)

    WDTCTL = WDTPW | WDTHOLD;               // Stop WDT

    // GPIO Setup

    P1DIR |= BIT0;                          // Set P1.0/LED to output
    P1SEL1 |= BIT1;                         // Configure P1.1 for ADC
    P1SEL0 |= BIT1;

    // disable the GPIO power-on default high-impedance mode to activate
    // prevIoUsly configured port settings
    PM5CTL0 &= ~LOCKLPM5;

    // Configure ADC12
    ADC12CTL0 = ADC12SHT0_2 | ADC12ON;      // Sampling time,S&H=16,ADC12 on
    ADC12CTL1 = ADC12SHP;                   // Use sampling timer

这是修改后的版本，我无法让它工作。

    if(i = 0; i < 1000; i++){
     //result[i] = ADC12MEM0;
      ADC12CTL0 |= ADC12ENC | ADC12SC; // Sampling and conversion start
    }
    else{
        ADC12CTL0 &= ~ADC12ENC;

   //result = ADC12MEM0;

   break;                // Clear cpuOFF bit from 0(SR)
  default: break;
 }
}

所以，这是我正在尝试修改的 ADC 的 MSP430FR6989 示例代码。我想把存入寄存器ADC12MEM0的转换结果保存到int result[1000]中；用 if 语句。但是，我觉得我遗漏了一些部分，它也不会运行我的代码并给出错误消息。

**我最近刚刚从 YouTube 学习 C 语言，我遇到的所有数组教程都使用 printf 和 scanf 来存储来自用户输入的值。就我而言，我不需要用户输入。我需要在没有用户输入的情况下将存储值保存到数组中 1000 次。我在这里缺少什么？我在哪里可以找到有关我的案例的信息？

 case ADC12IV_ADC12IFG0:         // Vector 12: ADC12MEM0 Interrupt
    if(i = 0; i < 1000; i++){
     //result[i] = ADC12MEM0;
      ADC12CTL0 |= ADC12ENC | ADC12SC; // Sampling and conversion start
    }
    else{
        ADC12CTL0 &= ~ADC12ENC;
    }
   //result = ADC12MEM0;
   //ADC12CTL0 |= ADC12ENC | ADC12SC;
   break;                // Clear cpuOFF bit from 0(SR)
  default: break;

解决方法

我会将示例代码的 while (1) 替换为 for (i = 0; i < 1000; i++)，即。 e.保留在 main 中循环并在 ADC12_ISR 中一次处理一个转换中断的代码结构。您只需在 result[i] = ADC12MEM0; 之前插入 // Exit from LPM0 and continue executing main。
