Thanks for the replies! The FastLED works with no "ghost LEDs", but I still have some questions:
When changing leds[some_led_index].r, it actually changes the green value of the led. leds[some_led_index].g changes red. blue works normally. Is there anyone having same problems? Thanks.
This is the current settings I'm using:
#define M5_NEO_NUM 10
#define M5_NEO_PIN 15
CRGB leds[M5_NEO_NUM];
void setup()
FastLED.addLeds<SK6812, M5_NEO_PIN>(leds, M5_NEO_NUM);
// other setups...
}
Compiler complains that No hardware SPI pins defined. All SPI access will default to bitbanged output, so I also tried WS2811, but the same problem continues.
The revelant code:
void setLedSingleChannelValue(int led_no, String channel, int val) {
Serial.println("led_no " + (String)led_no + ", channel " + channel + ", val " + (String)val);
if (channel == "R") {
if (led_no < 10) {
leds[led_no].red = val;
}
else {
if (led_no == 10 || led_no == 11) {
for (int i = 0; i < 5; ++ i) {
leds[i].red = val;
}
}
if (led_no == 10 || led_no == 12) {
for (int i = 5; i < 10; ++ i){
leds[i].red = val;
}
}
}
}
else if (channel == "G") {
if (led_no < 10) {
leds[led_no].g = val;
}
else {
if (led_no == 10 || led_no == 11) {
for (int i = 0; i < 5; ++ i) {
leds[i].g = val;
}
}
if (led_no == 10 || led_no == 12) {
for (int i = 5; i < 10; ++ i){
leds[i].g = val;
}
}
}
}
else if (channel == "B") {
if (led_no < 10) {
leds[led_no].b = val;
}
else {
if (led_no == 10 || led_no == 11) {
for (int i = 0; i < 5; ++ i) {
leds[i].b = val;
}
}
if (led_no == 10 || led_no == 12) {
for (int i = 5; i < 10; ++ i){

}
}
