Seeed nRF52 mbed-enabled board - compiling error

[Loaded-Dice]

Hi everyone,
I got one of the XIAO BLE Sense - nRF52840 Boards and got compiling issues with fastLED.
My board library is the mbed-enabled version (Seeed nRF52 mbed-enabled board > Seeed XIAO BLE Sense - nRF52840) because it's the necessary board version to get the IMU to work properly.
Has anyone got this issue before?
I also tried the neopixel library, which works fine with this board.
I already looked through all nRF52 related issues here but had no luck.
Can I create a workaround where I "trick" fastLED into compiling without FastLED using any Hardware outputs?
I already got a lot of code from another project with a different platform/controller, and I want to use my old fastLED based code to fill the CRGB array and instead of using FastLED for the output, I copy the data to the neopixel structure.
Is this possible? And if so, how to implement this?
I also read about the planned implementation of a "null" platform, but also couldn't find more details about it.
Any help would be appreciated.
Best Regards

did you get this to work? im having the same issues and really need fastled

Hey there,

Unfortunately, I had to use a very sketchy solution to use FastLed features with the nRF52

If you just want to control addressable RGB LEDs in an easy way and could go without the advantages of the FastLED
library (like fast math-/ timing- / noise - / color - functions), then you can simply go with the
Adafruit_NeoPixel library -> https://github.com/adafruit/Adafruit_NeoPixel

But if you want to use those mentioned functions in particular, then you may have to do it with this
workaround:
Use this core: Seeed Studio nRF52 Boards v1.1.1 (not mbed)

include the FastLED library

And create an CRGB leds[NUM_LEDS]; array for your LEDs
and don't initialize the hardware ( = avoid FastLED.addLeds... ) otherwise the build will fail.

Also include Adafruit_NeoPixel.h
and here you initialize
Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LEDS, LED_PIN, NEO_GRB + NEO_KHZ800);
Or whatever LED controller you might have.

Then you can use the FastLED color functions on your CRGB array and copy the data from the virtual CRGB array to the Neopixel strip.

void fastToNeo(){for(int i = 0; i < NUM_LEDS; i++){ strip.setPixelColor(i, leds[i].r, leds[i].g, leds[i].b); }}

you can find my working nRF52 + FastLED & Neopixel project here

good luck & regards

awesome, thanks! the idea is understandable, but the execution is rather complicated. Would it be possible for you to write a blink sketch for me? it would be highly appreciated!

[kakapo5140cc0]

i am reading through the whole project.. its awesome! definitely going to take some snippets of your code later... just trying to digest it as good as possible

[kakapo5140cc0]

i got it working!! thanks so much

[Loaded-Dice]

Great job! :)

But writing down a simple example to a workaround, that I found years ago, might be a great Idea anyway.
Just in case anyone else stumbles across this problem:
Here is a simple workaround to get FastLed working with the XIAO nRF52:

Whats your sketch?

I'm about to push a fix that will make the compiler errors not be 20 pages long for this chipset. The problem is that we only define valid pins. Invalid pins go through a default FastPin template which is missing function/value definitions that the compiler is expecting will exist and you get a weird error that is very very long.

For the NRF52 series I'm introducing an invalid pin specification that binds to a specialization of the FastPin<> type that will static_assert in a clean way.

I suspect that you used one of these invalid pins and that this was causing your issue and it's not obvious what the fix is to the average user.

[Loaded-Dice]

Hi,
the sketch that caused the issue in the first place is this one:
https://github.com/Loaded-Dice/Nightstick/tree/main/Nightstick-Arduino
Which boils down to a Xiao nRF52840 Sense Board, where I used pin D1 ( P0.03_AIN1_LOW_A1_D1 )
Which didn't work, apparently.

I'm looking forward to your updates.
Best regards

[zackees]

It's an invalid pin because it's used for UART RX. It probably works but kills external Serial output? Or maybe it just doesn't work at all. Hard to tell. Anyway, master now has this fix and it will compile and attempt to run. No idea if it will generate a core panic, but if it does that, you'll get a nice message on the output console that the pin isn't supported and a 2 second delay before it attempts to run.

Good luck!

I'm missing something because it still won't compile.

Btw, you should convert your project to platformio, which features a real build system and a real IDE. If your project was platformio then I could just open it up and everything would just download and install. No selection of board, no selection of packages, no finding out which port I need. Everything just works. The entire Arduino package ecosystem is also available.

It works with *.ino files and should just be 100% compatible with your source code, though you might have to move all your files except the root *.ino file to the src/ directory.

Anyway, here's the error code. To continue working on this I need to know either what the ArduinoIDE steps are or have you do a quick conversion to PlatformIO.
