Hello, I know this question has already been asked a couple times but the solutions do not work for me.
I have this circuit (sorry, not really professional, it's just for cosplay purpose).
I use this code:
#include <Adafruit_NeoPixel.h>
class Strip
{
public:
uint8_t effect;
uint8_t effects;
uint16_t effStep;
unsigned long effStart;
Adafruit_NeoPixel strip;
Strip(uint16_t leds, uint8_t pin, uint8_t toteffects, uint16_t striptype) : strip(leds, pin, striptype) {
effect = -1;
effects = toteffects;
Reset();
}
void Reset(){
effStep = 0;
effect = (effect + 1) % effects;
effStart = millis();
}
};
struct Loop
{
uint8_t currentChild;
uint8_t childs;
bool timeBased;
uint16_t cycles;
uint16_t currentTime;
Loop(uint8_t totchilds, bool timebased, uint16_t tottime) {currentTime=0;currentChild=0;childs=totchilds;timeBased=timebased;cycles=tottime;}
};
Strip strip_0(40, 6, 40, NEO_GRB + NEO_KHZ800);
struct Loop strip0loop0(1, false, 1);
//[GLOBAL_VARIABLES]
void setup() {
//Your setup here:
strip_0.strip.begin();
}
void loop() {
//Your code here:
strips_loop();
}
void strips_loop() {
if(strip0_loop0() & 0x01)
strip_0.strip.show();
}
uint8_t strip0_loop0() {
uint8_t ret = 0x00;
switch(strip0loop0.currentChild) {
case 0:
ret = strip0_loop0_eff0();break;
}
if(ret & 0x02) {
ret &= 0xfd;
if(strip0loop0.currentChild + 1 >= strip0loop0.childs) {
strip0loop0.currentChild = 0;
if(++strip0loop0.currentTime >= strip0loop0.cycles) {strip0loop0.currentTime = 0; ret |= 0x02;}
}
else {
strip0loop0.currentChild++;
}
};
return ret;
}
uint8_t strip0_loop0_eff0() {
// Strip ID: 0 - Effect: Rainbow - LEDS: 40
// Steps: 40 - Delay: 20
// Colors: 3 (255.0.88, 255.67.255, 113.0.255)
// Options: rainbowlen=40, toLeft=true,
if(millis() - strip_0.effStart < 20 * (strip_0.effStep)) return 0x00;
float factor1, factor2;
uint16_t ind;
for(uint16_t j=0;j<40;j++) {
ind = strip_0.effStep + j * 1;
switch((int)((ind % 40) / 13.333333333333334)) {
case 0: factor1 = 1.0 - ((float)(ind % 40 - 0 * 13.333333333333334) / 13.333333333333334);
factor2 = (float)((int)(ind - 0) % 40) / 13.333333333333334;
strip_0.strip.setPixelColor(j, 255 * factor1 + 255 * factor2, 0 * factor1 + 67 * factor2, 88 * factor1 + 255 * factor2);
break;
case 1: factor1 = 1.0 - ((float)(ind % 40 - 1 * 13.333333333333334) / 13.333333333333334);
factor2 = (float)((int)(ind - 13.333333333333334) % 40) / 13.333333333333334;
strip_0.strip.setPixelColor(j, 255 * factor1 + 113 * factor2, 67 * factor1 + 0 * factor2, 255 * factor1 + 255 * factor2);
break;
case 2: factor1 = 1.0 - ((float)(ind % 40 - 2 * 13.333333333333334) / 13.333333333333334);
factor2 = (float)((int)(ind - 26.666666666666668) % 40) / 13.333333333333334;
strip_0.strip.setPixelColor(j, 113 * factor1 + 255 * factor2, 0 * factor1 + 0 * factor2, 255 * factor1 + 88 * factor2);
break;
}
}
if(strip_0.effStep >= 40) {strip_0.Reset(); return 0x03; }
else strip_0.effStep++;
return 0x01;
}
When I connect my prop to the PC via the USB cable everything works but when I plug it off and turn on my switch the animation is gone. The LEDs still light up but without the animation.
