Feather RP2040 - built-in NeoPixel - PIN number?

by SOlson on Tue Dec 07, 2021 10:26 pm

Hi. I'm trying to access the built-in NeoPixel on the Feather RP2040 using the Arduino IDE. What parameters do I use in the "Adafruit_NeoPixel" Constructor?

Example:

// Argument 1 = Number of pixels in NeoPixel strip
// Argument 2 = Arduino pin number (most are valid)
// Argument 3 = Pixel type flags, add together as needed:
Adafruit_NeoPixel strip = Adafruit_NeoPixel(1, 6, NEO_GRB + NEO_KHZ800);

Thanks.

According to the pinout diagram https://learn.adafruit.com/assets/105204 it's on pin 27, GP16.

Is such a diagram also available for the ItsyBitsy Rp2040?

No, but the tutorial guide has a description of the pins, as well as the schematic. See https://learn.adafruit.com/adafruit-itsybitsy-rp2040.

Thanks Dave. I would have loved to get the pinout schematic to pin it on my desktop, it's a bit of a shame that the ItsyBitsy Rp2040 is not getting the same treatment as other boards ;)
