Why is the color function from adafruit keep failing with millis() in arduino (c++)?
I tried to make a alexa device with the wemos d1 mini and the arduino ide. I started by using the example called "fauxmoESP_basic" which is included in the fauxmoESP library. I then implemented the adafruit neopixel library to controll some of my ws2812b rgb leds. At this moment i can turn all leds to one color. But i wanted to make this rainbow effect like in the example sketch from the adafruit neopixel library that was called "strandtest".
The function looks like this:
void theaterChaseRainbow(int wait) {
int firstPixelHue = 0; // First pixel starts at red (hue 0)
for(int a=0; a<30; a++) { // Repeat 30 times...
for(int b=0; b<3; b++) { // 'b' counts from 0 to 2...
strip.clear(); // Set all pixels in RAM to 0 (off)
// 'c' counts up from 'b' to end of strip in increments of 3...
for(int c=b; c<strip.numPixels(); c += 3) {
// hue of pixel 'c' is offset by an amount to make one full
// revolution of the color wheel (range 65536) along the length
// of the strip (strip.numPixels() steps):
int hue = firstPixelHue + c * 65536L / strip.numPixels();
uint32_t color = strip.gamma32(strip.ColorHSV(hue)); // hue -> RGB
strip.setPixelColor(c, color); // Set pixel 'c' to value 'color'
}
strip.show(); // Update strip with new contents
delay(wait); // Pause for a moment
firstPixelHue += 65536 / 90; // One cycle of color wheel over 90 frames
}
}
}
But because you cant use delay you need to use millis() to get it running. As soon as I decide to use the millis() I realized that you cant use millis() together with for-loop's. So i tried rewriting the whole function. That's my solution:
if(a < 30) {
if(b < 3) {
strip.clear();
if(c < strip.numPixels()) {
int hue = firstPixelHue + c * 65536L / strip.numPixels();
uint32_t color = strip.gamma32(strip.ColorHSV(hue));
strip.setPixelColor(c, color);
c += 3;
} else {
strip.show();
unsigned long currentMillis = millis();
if(currentMillis - previousMillis > 50) {
firstPixelHue += 65536 / 90;
b++;
c = b;
}
}
} else {
b = 0;
a++;
}
}
It should work. I dont see a mistake. I hope you can help me. everytime i execute this function it crashes and i get this over the serial monitor:
Exception (28):
