用NeoPixels实现Arduino函数的不正确循环

Question

在我工作的地方，我正在用Arduino + NeoPixels来点亮一个万圣节的标志。我的两个功能之一(缓慢，传播，红色辉光)工作良好。另一个--心跳减慢--从来没有慢下来，似乎陷入了一个无限的循环。

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);
}

从数学上讲，我应该每分钟交一定的拍数，计算出每拍秒数，光脉冲超过60%，脉冲再超过30%，然后保持10%的静音。这应该发生20次，每个节拍逐渐变慢，直到完全停止。

相反，我正以每秒一次的速度稳定地闪烁。

我确信它最终会被我完全忽略，或者在NeoPixel文档中被忽略了。但是，由于我不是忽略了它，就是完全错过了它，我将感激你的帮助。:)

在这里，您试图在声明void diastolicDown(int i) { beatSeconds = 60000/i; uint16_t beatSeconds, secondPulse, secondIncrement, j, k;之前将一个值赋值给beatSeconds。
