ItsyBitsy RP2040

Post by Mor »

Hi,
I have new Adafruit ItsyBitsy RP2040 board https://www.adafruit.com/product/4888.

When I connect him to my computer with usb, I can see the board drive(RPI-RP2)
The problem is when i try copy + paste any UF2 (Even Blink.uf2) to board drive,
when the copy finished, the drive automatic close, and nothing not occur.
When i oppen this again(with the bootloader) the new file not appeared.

The another problem is wich the neopixel never turn on

Where did the blink.uf2 you are copying come from?

Have you tried blink from within Arduino? https://learn.adafruit.com/adafruit-its ... 40/blink-2

The RPI-RP2 "drive" is essentially a place to send firmware files to so they get stored in flash to be executed. You can consider it write-only for all intents and purposes.

Are you running code that would turn the NeoPixel on?

Hi,
Thank you about your quick answeer,
I am try copy the UF2 From https://www.raspberrypi.com/documentati ... c_sdk.html

About your sample from arduino, is great, Now i know the problem is not in the board.
But the problem is that I have a task that I don't know how to do,
I need to write firmware for the board, so that I can turn LedtStrip on and off from a computer connected to it via USB by c# code.

I used to use the FadeCandy https://www.adafruit.com/product/1689 board, but it is no longer sold.
Maybe you can advise me how to start?
Maybe you have an example of such a project?

You say you have an ItsyBitsy RP2040, but that UF2 is for a Raspberry Pi Pico. These are different boards.

Fadecandy is a standalone NeoPixel controller. You can build something similar with your ItsyBitsy. However if you really need to control 8 strands, I suggest a NeoPXL8 Friend https://www.adafruit.com/product/3975 but you'll need a SAMD21 or SAMD51 board to run it. There are specific versions (https://www.adafruit.com/product/3249 and https://www.adafruit.com/product/4537) for the Feather M0 and M4, respectively.

There are many NeoPixel projects at https://learn.adafruit.com/.
