Hello I'm new to RP2040
I have a YD-RP2040
And it have a built-in WS2812
I have already test "Adafruit_NeoPixel.h"'s example but nothing happens
I'm Using Arduino IDE 2.0.2
Does "Adafruit_NeoPixel.h" compatible YD-RP2040?
I'm Using Arduino IDE 2.0.2
Thank you very much for your help!
Hi Eric, I just received the same board and struggled a bit to make that led functionning. I found the schematic there: https://99tech.com.au/mx-m/rp/rp2040-yd_schematics.pdf
By default the RGB resistor (written R68 on the board) is not connected to allow you to use GPIO23 freely. If you want to connect that pin to the RGB led you have to solder the two pads together.
Hope that helps!

Hi mate, just making sure I understand correctly.
If I want to make use of the addressable RGB led via the WS2812 protocol, I then need to solder the two pads indicated by the R68 resistor on the board. This means that that the GPIO23 will always be linked to the RGB led and as opposed to its factory status, which is independent. When you solder the pads, you make a naked soldering, without any actual resistor, right?
If you could please confirm that, I would highly appreciate it.
