I am trying to make a program to control matrix LED using fastLED library. I have 4 buttons where each button activate the corresponding animation. But I want the program to be able to start animating one of the animation functions I made once the program is starting before any button is pressed. I already wrote a working LED matrix animation program that works individually but when I put it in the setup it only runs the first frame and won't animate. I also tried putting the function inside while(1) it won't get interrupted and transition to another animation when the button is pressed. Anyway where I can animate the first initial animation before other buttons are pressed?
The code is as shown below and 'firstanimation()' is the function I want to animate on start up. I won't post the code for the animation as it is very long.
void setup()
{
pinMode(tx, INPUT);
pinMode(rx, OUTPUT);
delay(50);
Serial.begin(9600);
BT.begin(9600);
pinMode(btn1, INPUT);
pinMode(btn2, INPUT);
pinMode(btn3, INPUT);
pinMode(btn4, INPUT);
pinMode(btn5, INPUT);
FastLED.setDither(1);
FastLED.addLeds<NEOPIXEL, DATAPIN>(leds, LEDNUM).setCorrection(TypicalPixelString); // tone down the blue. more warm
FastLED.setBrightness(BRIGHTNESS);
FastLED.setMaxPowerInVoltsAndMilliamps(5, 39500); // power management in v and mA
}
void loop()
{
BT.listen();
int c = BT.read();
delay(30);
if (digitalRead(btn1) == HIGH && is_fog != 1)
{
Serial.println("btn1 pressed");
is_fog = 1;
is_rain = 0;
is_rlight = 0;
is_sun = 0;
is_wind = 0;
}
else if (digitalRead(btn2) == HIGH && is_rain != 1)
{
Serial.println("btn2 pressed");
is_fog = 0;
is_rain = 1;
is_rlight = 0;
is_sun = 0;
is_wind = 0;
}
else if (digitalRead(btn3) == HIGH && is_rlight != 1)
{
Serial.println("btn3 pressed");
is_fog = 0;
is_rain = 0;
is_rlight = 1;
is_sun = 0;
is_wind = 0;
}
else if (digitalRead(btn4) == HIGH && is_sun != 1)
{
Serial.println("btn4 pressed");
is_fog = 0;
is_rain = 0;
is_rlight = 0;
is_sun = 1;
is_wind = 0;
}
else if (digitalRead(btn5) == HIGH && is_wind != 1)
{
Serial.println("btn5 pressed");
is_fog = 0;
is_rain = 0;
is_rlight = 0;
is_sun = 0;
is_wind = 1;
}
if (is_fog == 1)
{
state = 0;
animation1();
}
else if (is_rain == 1)
{
state = 3;
animation2();
}
else if (is_rlight == 1)
{
state = 0;
animation3();
}
else if (is_sun == 1)
{
state = 0;
animation4();
}
else if (is_wind == 1)
{
state = 2;
animation5();
}
For your reference, the firstanimation function is as follow:
#define FASTER 1
#define TIMING 1
byte bump[LEDNUM];
void generatebumpmap()
{
uint16_t t = millis() / 11; faster
int index = 0;
for (int j = 0; j < ROWS; j++)
{
for (int i = 0; i < COLS; i++)
{
byte col;
uint16_t u, v;
u = i * (36 + 4) + t / 5;
v = j * (23 + 6) - t / 3;
if (!FASTER)
{
col = inoise8(u, v, t);
col = map(col, 0, 255, 0, 255);
}
else //FASTER==1
{
col = 76 + inoise8_raw(u, v, t);
}
bump[index++] = col;
}
}
}
void Bumpmap(int8_t lightx, int8_t lighty)
{
int yindex = COLS;
int8_t vly = lighty;
for (int y = 1; y < ROWS - 1; y++)
{
++vly;
int8_t vlx = lightx;
for (int x = 1; x < COLS - 1; x++)
{
++vlx;
int8_t nx = bump[x + 1 + yindex] - bump[x - 1 + yindex];
int8_t ny = bump[x + yindex + COLS] - bump[x + yindex - COLS];
if (!FASTER)
{
byte difx = abs8(vlx - nx);
byte dify = abs8(vly - ny);
int col = 255 - sqrt16(difx * difx + dify * dify) * 3;
if (col < 0)
col = 0;
leds[XY(x, y)] = CHSV(250, 255, col);
}
else
{
uint16_t sumsquare = (vlx - nx) * (vlx - nx) + (vly - ny) * (vly - ny);
byte col = 0;
if (sumsquare < 7225) // 7225 == (255 / 3)²
col = 255 - sqrt16(sumsquare) * 3;
leds[XY(x, y)] = chsv[col];
}
}
yindex += COLS;
}
}
void firstanimation() {
/////COLORRR
for (int i = 0; i < 256; i++) {
chsv[i] = CHSV((i / 1.5 ) + 16 , 255, i); //+60
//chsv[i] = CHSV((i / 1.5) + 16 , fogvar, i);
}
int time = millis() / 8;
int8_t lightX = 1 - (sin8(time / 3) - 128) / 3.2; // beatsin8(20,0,80);
int8_t lightY = 1 - (sin8(time / 2) - 128) / 3.1; // beatsin8(25,0,80); //
unsigned long t1 = micros();
generatebumpmap();
unsigned long t2 = micros();
Bumpmap(lightX, lightY);
unsigned long t3 = micros();
FastLED.show();
if (TIMING)
{
static unsigned long t2_sum, t3_sum;
t2_sum += t2 - t1;
t3_sum += t3 - t2;
static byte frame;
if (!(++frame % 64))
{
t2_sum = t3_sum = 0;
}
}
}
I tried putting multiple function in void loop and and void setup and none of it worked.
