so i have a working code for 32 channel relay broad running on one of the megas
const int numChannels = 32;
// List Arduino pins in Channel number order
int channels[numChannels] = {2,3,4,5,6,7,8,9,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45};
int incomingByte[numChannels];
void setup()
{
Serial.begin(9600);
for(int i = 0; i < numChannels; i++){
pinMode(channels[i], OUTPUT);
// Start with lights turned off
//digitalWrite(channels[i],0);
digitalWrite(channels[i],0);
}
}
void loop()
{
if (Serial.available() >= numChannels)
{
for (int i=0; i<numChannels;i++)
incomingByte[i] = Serial.read();
for(int i = 0; i < numChannels; i++)
//digitalWrite(channels[i], incomingByte[i]);
digitalWrite(channels[i], incomingByte[i]);
//LED STUFF
}
}
fastled test works fine.
but this code and vixen do radom things.
what did i do wrong with the code?
void setup() {
FastLED.addLeds<WS2811, PIN, RGB>(leds, NUM_LEDS);
Serial.begin(115200);
}
void loop() {
for(int i = 0; i < NUM_LEDS; i++) {
if (Serial.available() > 2) {
Serial.readBytes( (char*)leds, NUM_LEDS * 3);
}
FastLED.show();
}
}
one of the main things it will do is start at light 2 for light 1, even though i made sure the controller points to the right spot
any help would be aprecited thanks
this coden works for pixels 1-21 then the rest are wierd
#include <Adafruit_NeoPixel.h> // This is the Neo-Pixel library (ws2812)
// Change to the library for your pixel types
// Suggest using a library created by Adafruit
// so the function names will be the same
#define DPIN 6 // Change this to the pin# connected to your pixels DataIn
// Will probably need to define a ClockPin for other pixel
int PixelCount = 150; // Set this to the number of Pixels connected
int bugLevel = 0; // This is just a way I manage turning debugging over serial on/off
/* Sets up the NeoPixel Strip object
Replace with proper Object initiation for your pixel types */
Adafruit_NeoPixel strip = Adafruit_NeoPixel(150, DPIN, NEO_RGB + NEO_KHZ800);
void setup()
{
delay(50); // A delay for a reason I can't remember. I can live with one in the setup.
strip.begin(); // Get strip started
strip.show(); // Initialize all pixels to 'off'
Serial.begin(115200); // Start the Serial communication
bugit("Setup Complete",0); // DEBUG: Confirm setup is complete
}
void loop()
{ // START LOOP

for (int pixCount=0; pixCount<PixelCount;pixCount++) // Do this for as many Pixels defined in PixelCount
{
int RGB[3]; // Create array to hold this pixels RGB value
for (int color = 0;color<3;color++) // For the next 3 incoming bytes
{
while (Serial.available() < 1) // Wait for bytes to be received
{
delay(10);
}
RGB[color] = Serial.read(); // Save this byte to the correct RGB value
} // Repeat until bytes for this pixels RGB value have been recieved
strip.setPixelColor(pixCount,RGB[0],RGB[1],RGB[2]); //Set this pixels new color
} // Repeat untill all pixels have had new RGB value set
strip.show(); // Update the strip and show with new color
} // YAY! DO IT AGAIN!
} // END OF LOOP
