adafruit feather rp2040 scorpio / CMakeLists.txt

[StefanD17]

Hello,

Thank you very much for all your work.
I have a working setup so far:

Raspberry PI 3 B
+
adafruit feather rp2040 scorpio
+
SK6812

SingleSegment is now working. I downloaded the firmware directly from https://github.com/awawa-dev/HyperSerialPico/releases/download/v4.0.0.0/Adafruit_Feather_RP2040_Scorpio.zip.

I would like to use Multi Segment.
It is described here:
https://github.com/awawa-dev/HyperSerialPico/wiki

In my case with the rp2040 scorpio, I am not sure about
set(OUTPUT_DATA_PIN 2)
.

Would the following be correct for me?
set(OUTPUT_DATA_PIN 16) -> Since it's on Scorpio GPIO 16

Multisegment should then be clear, the second segment will be on GPIO 17, right?

Thank you very much for your help!

Hi
Well, it’s technically described in the manual which GPIO is used, but you can also verify it here where we build the release for this board:

HyperSerialPico/.github/workflows/push-master.yml

Line 47 in 40f8b6b

- name: Build packages for Adafruit Feather RP2040 Scorpio (release-only)

For Neopixel, the following elements are key for Scorpio::
-DOVERRIDE_BOOT_WORKAROUND=ON -DOVERRIDE_DATA_PIN=16
So OUTPUT_DATA_PIN=16 (if second segment is enabled it uses next GPIO=17, but you do not need to configure it) and enable BOOT_WORKAROUND as first revisions of this board are known to have a problem with unstable start-up.

@awawa-dev Thank you very much. The LEDs are now lit, but I have one last stupid question about the multi-segment. Does it matter whether I have the two ends of the LED strip at the top or bottom of the TV? Or does it not matter because I can configure the input position in HyperHDR?

[awawa-dev]

It doesn't matter, as you've noted you'll configure the appropriate settings in HyperHDR later. It's usually easier to avoid gaps between the two segments at their ends than at the beginning, where there'll be a tangle of cables. So I simply suggest placing the ends at the top, as there's usually a stand at the bottom that will obscure the gap anyway.
