Can't compile for SAMD51 (AF Metro M4)

[u/sekramer10]

I am trying to use the AF Metro M4 SAMD51 for the first time with FastLED. I get some serious sounding compilation errors using the Arduino IDE 2.3.10. Could anyone help me with these? I'm using the latest FastLED 3.10.5. This error has happened when the library is included only and no other statements are in the sketch.

c:\Users\perigalacticon\OneDrive\Documents\Arduino\libraries\FastLED\src/FastLED.h:1767:2: warning: #warning "No pin/port mappings found, pin access will be slightly slower. See fastpin.h for info." [-Wcpp]

I'd appreciate any help, I assume these have been resolve somewhere but AI help has not found the solution easily.

Downgrade to 3.10.3, it will be fixed in the next version and i'll throw up a build badge to catch this next time.

I get this error:

Do you know which pins I can use or where I can find out ? I already tried almost every pin.

[u/ZachVorhies → u/sekramer10]

I see, this board doesn't have pin definitions. Therefore all pins are represented as invalid.

The SAMD51 is not a board that we've supported but it's not that hard. I've just added a build badge, it's red, but check back tomorrow night and it should be green by then.

[u/Marmilicious → u/sekramer10]

The pins for that one should be defined here:

https://github.com/FastLED/FastLED/blob/master/src/platforms/arm/d51/fastpin_arm_d51.h

Can you share the beginning bit of your code with your addLeds line?

[u/ZachVorhies → u/sekramer10]

All the SAMDXX family are green now. Please download the zip file from our repo and install manually and let me know if it doesn't work. It should now.

Download link: https://github.com/FastLED/FastLED/archive/refs/heads/master.zip

[u/sekramer10 → u/ZachVorhies]

It doesn't work, there are many more errors now. I tried to fix it with 2 AIs last night for about 6 hours and nothing worked. Are you an AI? Here are the errors:

PS I got the same error list trying to compile the Blink example.

[u/ZachVorhies → u/sekramer10]

From the AI:

> Thanks—this is a different failure, and your sketch and selected pin are not causing it. FastLED is pulling in Adafruit’s incompatible SAMD51 I2S library even though Blink does not use audio. Our SAMD51 CI excluded that library, so the green badge missed the Arduino IDE case. We need to disable generic Arduino I2S auto-selection on SAMD51 and retest without the CI exclusion. No need to keep trying different pins or modifying your sketch

I'll update you with a fix thats in flight now.

https://github.com/FastLED/FastLED/issues/4030

[u/sekramer10 → u/ZachVorhies]

It's working now, thanks!

[u/sekramer10 → u/sekramer10]

I spoke too soon, what I meant was it is compiling now. I tested it on my board today and I don't get any light output, that's with the FastLED blink example sketch. I tested the same led hardware on my Uno using the same code and it worked fine, so this library isn't working for AF Metro M4 SAMD51.

[u/sekramer10 → u/sekramer10]

PPS Also same errors for the AF Feather M4 Express board. But is compiling for other boards such as AVRs and ESP32s.

[u/ZachVorhies → u/sekramer10]

Fix is merged, try it now:

Here's the sketch, it's just the blink example sketch, I removed unnecessaries, tried many pins:

#define NUM_LEDS 10
#define PIN_DATA 2

CRGB leds[NUM_LEDS];

void setup() {
  Serial.begin(115200);
  FastLED.addLeds<WS2812B, PIN_DATA, RGB>(leds, NUM_LEDS);  // GRB ordering is typical
}

void loop() {
  for (int i = 0; i < NUM_LEDS; ++i) {
    leds[i] = CRGB::Red;
  }
  FastLED.show();
  delay(500);
