Question

我在我的工作地点使用Arduino + NeoPixels为万圣节制作动画/点亮标志。我的两个功能之一（缓慢，扩散，红色发光）工作正常。另一个 - 心跳减慢 - 从不放慢速度，似乎陷入无限循环。

以下是完整的相关代码：

void loop() {
    // HeartBeat Test
   for(int bpm=60;bpm >= 0;bpm=bpm-3) {
       systolicUp(bpm);
       systolicDown(bpm);
       diastolicUp(bpm);
       diastolicDown(bpm);
       restBeat(bpm);
   }
}


void systolicUp(int i) {
    uint16_t beatSeconds, firstPulse, firstIncrement, j, k;
    beatSeconds =  60000/i;
    firstPulse = beatSeconds * 0.6;
    firstIncrement = firstPulse/170;
    for(j=0; j <= 255; j=j+3) {
        uint32_t redShade = strip.Color(j, 0, 0);
        for (k=0; k<strip.numPixels(); k++) {
            strip.setPixelColor(k, redShade);
        }
        strip.show();
        delay(firstIncrement);
    }
}

void systolicDown(int i) {
    uint16_t beatSeconds, firstPulse, firstIncrement, j, k;
    beatSeconds =  60000/i;
    firstPulse = beatSeconds * 0.6;
    firstIncrement = firstPulse/170;
    for(j=255; j >= 0; j=j-3) {
        uint32_t redShade = strip.Color(j, 0, 0);
        for (k=0; k<strip.numPixels(); k++) {
            strip.setPixelColor(k, redShade);
        }
        strip.show();
        delay(firstIncrement);
    }
}

void diastolicUp(int i) {
    uint16_t beatSeconds, secondPulse, secondIncrement, j, k;
    beatSeconds =  60000/i;
    secondPulse = beatSeconds * 0.3;
    secondIncrement = secondPulse/170;
    for(j=0; j <= 255; j=j+3) {
        uint32_t redShade = strip.Color(j, 0, 0);
        for (k=0; k<strip.numPixels(); k++) {
            strip.setPixelColor(k, redShade);
        }
        strip.show();
        delay(secondIncrement);
    }
}

void diastolicDown(int i) {
    beatSeconds =  60000/i;
    uint16_t beatSeconds, secondPulse, secondIncrement, j, k;
    secondPulse = beatSeconds * 0.3;
    secondIncrement = secondPulse/170;
    for(j=255; j >= 0; j=j-3) {
        uint32_t redShade = strip.Color(j, 0, 0);
        for (k=0; k<strip.numPixels(); k++) {
            strip.setPixelColor(k, redShade);
        }
        strip.show();
        delay(secondIncrement);
    }
}

void restBeat(int i) {
    uint16_t beatSeconds, rest, g;
    beatSeconds =  60000/i;
    rest = beatSeconds * 0.1;
    for (g=0; g<strip.numPixels(); g++) {
        strip.setPixelColor(g, 0, 0, 0);
    }
    strip.show();
    delay(rest);
}

通过数学计算，我应该每分钟交换一定数量的节拍，计算每次拍子的秒数，光脉冲超过60％，脉冲再次超过30％，并且然后沉默10％。这应该发生20次，每次拍打逐渐变慢，直到它完全停止。

相反，我每秒钟都会稳定闪烁。

我确定它最终会成为我在NeoPixel文档中完全忽略或遗漏的东西。但是，由于我要么忽视它，要么完全错过它，我们将不胜感激。：）

Answer 1

void diastolicDown(int i) { beatSeconds = 60000/i; uint16_t beatSeconds, secondPulse, secondIncrement, j, k; 在这里，您尝试在声明之前为beatSeconds分配值。

使用NeoPixels的Arduino函数无法正常循环
