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

Re: ItsyBitsy RP2040
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?

Re: ItsyBitsy RP2040
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?

Re: ItsyBitsy RP2040
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/.
