Request: Add support for RP2354 chip with wireless module

[bixxewoscht]

Similar to a PICO2W I made a small PCB that has the RP2354 Processor variant with the Raspberry Pi Radio Module 2.
So it basically is a PICO2W without external flash memory.

It would be great if that could also be supported. With the original OGXMini from wiredopposite its possible to connect and inputs are registered, but after a minute or so the controller disconnects, possibly due to a memory issue.

With your version for the 2W I was able to connect but no buttons were registered.

If you need one of my PCBs to test let me know.

Thanks for your effort so far!

I'd be interested in getting a PCB from you and adding support at a later time. I'm mid moving so I'm just getting back into the project in my spare time.

Ok, I'm happy to send you a unit! You can reach me via mail bixxewoscht@outlook.com once you're ready to give me your adress.

Just to confirm, have you confirmed there are libraries to support your given chip and module? Because if Bluepad32 and TinyUSB dont support your board then this wont work for you and Im not able to redo their drivers just for a specific build to your board.

As its just a variant of the processor of the Raspberry Pi Pico2W, tbh. I just assumed it works.
The only difference is that it has 2MB internal flash memory instead of the 4MB external memory chip that is on the PICO2W.
So in theory, if 2MB of flash are enough, everything else should be work exactly the same.

With the original version of OGXMini by wiredopposite, my PCB works fine until the controller disconnects after ~1min.
So it looks like hopefully only a small adaptation is needed.

Thanks for pointing out the dependencies though, I have asked on the GitHub pages of the projects if this processor variant is supported.

I didnt realize I already had a build option for this board in my project, it must have been one of the first things I added when I started. Try this build and see if it works for your board.

I just tried it, but it didn't work. The XBOX One Controller I'm using was not able to connect.
After the flashing was done, the LED also didn't blink.
In comparison, when I flashed wiredopposites version again, the LED blinked after flashing was done.
The board is using the same IO for the LED as the PICO2W.

Does it have the same wireless module as the Pico W models?

[bixxewoscht]

Yes, it uses the Raspberry Pi Radio Module 2, which is a standalone version of the radio module on the Pi Picos.

The connection GPIOs to the host processor and everything else should be 1:1 the same.
You can find information about it here, including the datasheet: https://www.raspberrypi.com/news/raspberry-pi-radio-module-2-available-now-at-4/

RP2354 Test 2.zip

Try this for me and let me know if it works for you.

Success!! There is progress now, thanks!
With your new version pairing works. The connection drops again a bit randomly after a short while (between a few seconds and 1 - 2 minutes). But I was able to reconnect again and repeat. This was not possible with the version from wiredopposite.

If I can provide you anything else to make your life easier let me know.

Are you on the discord? Please feel free to message me so I can send you my PO box to get one of your boards so I can do testing with it. Thank you.
