I have a functioning prototype that works on UNO (ATmega328P). When I switch over to NANO (ATMEGA328), the behavior is all wrong. The project uses the FASTLed library with APA102 LEDs
I was getting a upload issue with the Arduino IDE (1.8.13) , updated the drivers and that issue appears to have been resolved. I get good compilations and uploads now.
Code is as follows:
#include <FastLED.h>
// How many leds in your strip?
#define NUM_LEDS 60
// For led chips like Neopixels, which have a data line, ground, and power, you just
// need to define DATA_PIN. For led chipsets that are SPI based (four wires - data, clock,
// ground, and power), like the LPD8806, define both DATA_PIN and CLOCK_PIN
#define LED_PIN 11 //GREEN
#define CLK_PIN 13 //BLUE
#define LED_TYPE APA102
#define COLOR_ORDER BGR
#define NUM_LEDS 58
#define BRIGHTNESS 150
#define FRAMES_PER_SECOND 10
// Define the array of leds
CRGB leds[NUM_LEDS];
const TProgmemRGBPalette16 MyLavaColors_p FL_PROGMEM =
{
CRGB::DarkRed,
CRGB::Maroon,
CRGB::DarkRed,
CRGB::Maroon,
CRGB::DarkRed,
CRGB::Maroon,
CRGB::DarkRed,
CRGB::DarkRed,
CRGB::DarkRed,

CRGB::DarkRed
};
const TProgmemRGBPalette16 MyForestColors_p FL_PROGMEM =
{
CRGB::DarkGreen,
CRGB::DarkGreen,
CRGB::DarkGreen, //DarkOliveGreen,
CRGB::DarkGreen,
CRGB::DarkGreen, //DarkOliveGreen,
CRGB::DarkOliveGreen, //DarkGreen,
CRGB::DarkGreen, //DarkOliveGreen,

};
CRGBPalette16 currentPalette(CRGB::Black); //initialize to BLACK for fade on affect
CRGBPalette16 targetPalette(MyLavaColors_p); //initialize target palette to LAVA colors
//CRGBPalette16 targetPalette(HeatColors_p);
//CRGBPalette16 targetPalette(ForestColors_p);
String palette = "Lava"; //used for debuging
const unsigned long lavaDur = 600000; //show lava for 600 seconds (10 minutes)
const unsigned long forestDur = 30000; //show forest for 30 seconds
unsigned long currentTime = 0; //initilize current timer
unsigned long previousTime = 0; //initialize previous timer
unsigned int x = 0; //used for debugging
void setup() {
/* used for debugging
Serial.begin(9600);
Serial.println("resetting");*/
delay(3000);
LEDS.addLeds<LED_TYPE, LED_PIN, CLK_PIN, COLOR_ORDER>(leds, NUM_LEDS); // APA102, WS8201
LEDS.setBrightness( BRIGHTNESS );
}
void loop() {
currentTime = millis(); //start timer
/* debugging, curious what is going on under the hood
EVERY_N_SECONDS(1) {
x++;
Serial.print(x);
Serial.print(": ");
Serial.print(" palette: ");
Serial.println(palette);
}*/
/* After 10 minutes, set color palette to Forest */
if (currentTime - previousTime >= lavaDur) {
targetPalette = CRGBPalette16(MyForestColors_p);
//palette = "Forest";
}
/* After 30 seconds, set color palette to Lava */
if (currentTime - previousTime >= lavaDur + forestDur) {
targetPalette = CRGBPalette16(MyLavaColors_p);
//palette = "Lava";
previousTime = currentTime;
}
/* Fill LEDS with noise colors */
fillnoise8();
/* fade colors from current palette to target palette */
EVERY_N_MILLIS(10) {
nblendPaletteTowardPalette(currentPalette, targetPalette, 48); // Blend towards the target palette over 48 iterations.
}
/* show LEDs */
LEDS.show(); // Display the LED's at every loop cycle.
}
void fillnoise8() {
#define scale 30 // Don't change this programmatically or everything shakes.
for (int i = 0; i < NUM_LEDS; i++) { // Just ONE loop to fill up the LED array as all of the pixels change.
uint8_t index = inoise8(i * scale, millis() / 10 + i * scale); // Get a value from the noise function. I'm using both x and y axis.
leds[i] = ColorFromPalette(currentPalette, index, 255, LINEARBLEND); // With that value, look up the 8 bit colour palette value and assign it to the current LED.
}
} // fillnoise8()
I suspect it is something that is not quite compatible in the FASTLed.fillnoise8() method.
Any ideas what may be going on?
