i want to run normal program with class type of program #2
Comments

Hello,
You can just load any example code into the arduino controller. There is
one parameter only - pin number pf neopixel ring. Change the pin number
on neopixel ring in the sketch you like and load it.
That's all you can do.
You can also write another sketch if you want.
Best regards, Alexander.
… Can i run "class" code with normal example code.
i try but only one of them is running. what should i do please tell me.
class example
class colorWipe: public animation {
public:
colorWipe(void) { w = random(256); }
virtual void init(void);
virtual void show(void);
private:
byte w;
int index;
bool fwd;
};
void colorWipe::init(void) {
int p = random(2, 4);
w += p*16 + 1;
fwd = random(2);
index = 0;
if (!fwd) index = strip.numPixels() - 1;
}
void colorWipe::show(void) {
uint32_t color = Wheel(w);
if (fwd) {
if (index > int(strip.numPixels())) { // Start new sequence with the
new color
init();
complete = true;
return;
}
strip.setPixelColor(index++, color);
} else {
if (index < 0) { // Start new sequence with the new color
init();
complete = true;
return;
}
strip.setPixelColor(index--, color);
}
complete = false;
}
//Normal example
void theaterChase(uint32_t c, uint8_t wait) {
for (int j=0; j<10; j++) { //do 10 cycles of chasing
for (int q=0; q < 3; q++) {
for (uint16_t i=0; i < strip.numPixels(); i=i+3) {
strip.setPixelColor(i+q, c); //turn every third pixel on
}
strip.show();
delay(wait);
for (uint16_t i=0; i < strip.numPixels(); i=i+3) {
strip.setPixelColor(i+q, 0); //turn every third pixel off
}
}
}
}
//only mgr.show is running in this loop
void loop() {
mgr.show();
theaterChase(strip.Color(127, 127, 127), 50); // White
theaterChase(strip.Color(127, 0, 0), 50); // Red
theaterChase(strip.Color(0, 0, 127), 50); // Blue
}
//what should i do please tell me.

thank you sir, void loop() { delay(wait); for (uint16_t i=0; i < strip.numPixels(); i=i+3) { |
|
It seems boring sequence. Just switch between three colors. It would be
better to change the color like the raindow sequence, smoothly. Drawing
each third pixel, like the original theaterChaser function.
What do you think about this improvement?

… thank you sir,
but i want to add more effects in your code but i don't know how to
convert that in class type
can u tell me how to convert this example like your code
void loop() {
theaterChase(strip.Color(127, 127, 127), 50); // White
theaterChase(strip.Color(127, 0, 0), 50); // Red
theaterChase(strip.Color(0, 0, 127), 50); // Blue
}
void theaterChase(uint32_t c, uint8_t wait) {
for (int j=0; j<10; j++) { //do 10 cycles of chasing
for (int q=0; q < 3; q++) {
for (uint16_t i=0; i < strip.numPixels(); i=i+3) {
strip.setPixelColor(i+q, c); //turn every third pixel on
}

yes u r right sir... |

Hi!
If you are still looking for the theaterChaseporting into the ws2812
strip. Here it is (see the attachment). You need one more time to fix
the 'randomize feature'. For your favorite animation i have created new
class -
theatChase.
Best regards, Alexander.
yes u r right sir...
this is the simple one that's why i choose this to learn how to
convert it class type or fit in u r program please tell me.....how can
i run this with u r program.

thank you so much sir........ i have one more request sir can u provide me lots of neo pixel examples which is written in regular type like gives in neo pixal library examples. |

i have this examples which is given in this link but i need more........ |

Hello!
You have sent me a great link to animation examples. Thank you very
much. I need some time to investigate them. Maybe some of them i could
add to the Xtmas strip.
Sorry, i have not much time to translate the animations from the class
to the 'regular' procedures.
As you can see, each class have two functions: init(), which is run
before the animation to initialize the animation parameters, and show(),
which performs ONE animation step. You could put the show() function
into the body of the loop.
…
thank you so much sir........

ok thank you sir, |

hello sir, i try the theater chase function but only one color(Green) is running. what should i do for other colors. void theatChase::init(void) { void theatChase::show(void) { if (++stp >= 3) stp = 0; |
|
As you can see, random color is generated by Wheel() function. Maybe the
issue is that he random generator was not initialized?
And you can replace w = random(265) to w = random(256); in the init()
function.

Can i run "class" code with normal example code.
i try but only one of them is running. what should i do please tell me.
class example
class colorWipe: public animation {
public:
colorWipe(void) { w = random(256); }
virtual void init(void);
virtual void show(void);
private:
byte w;
int index;
bool fwd;
};
void colorWipe::init(void) {
int p = random(2, 4);
w += p*16 + 1;
fwd = random(2);
index = 0;
if (!fwd) index = strip.numPixels() - 1;
}
void colorWipe::show(void) {
uint32_t color = Wheel(w);
if (fwd) {
if (index > int(strip.numPixels())) { // Start new sequence with the new color
init();
complete = true;
return;
}
strip.setPixelColor(index++, color);
} else {
if (index < 0) { // Start new sequence with the new color
init();
complete = true;
return;
}
strip.setPixelColor(index--, color);
}
complete = false;
}
//Normal example
void theaterChase(uint32_t c, uint8_t wait) {
for (int j=0; j<10; j++) { //do 10 cycles of chasing
for (int q=0; q < 3; q++) {
for (uint16_t i=0; i < strip.numPixels(); i=i+3) {
strip.setPixelColor(i+q, c); //turn every third pixel on
}
strip.show();
delay(wait);
for (uint16_t i=0; i < strip.numPixels(); i=i+3) {
strip.setPixelColor(i+q, 0); //turn every third pixel off
}
}
}
}
//only mgr.show is running in this loop
void loop() {
mgr.show();
theaterChase(strip.Color(127, 127, 127), 50); // White
theaterChase(strip.Color(127, 0, 0), 50); // Red
theaterChase(strip.Color(0, 0, 127), 50); // Blue
}
//what should i do please tell me.
