Raspberry Pi Pico uf2 build help?

[Zaf]

Hi Folks,

Not sure if anyone can help me, but I'm looking for someone who can build some code from GitHub and generate a uf2 file please?

Here's the main repository - https://github.com/fortizc/retro-pico-switch

There's a fork with the change I wanted but didn't have a uf2 build - https://github.com/fortizc/retro-pico-switch

Unfortunately, it looks like its 8 commits behind

I basically need it changing from GP18 to GP2 or GP3 so I can use a Seeed XIAO RP2040 instead of a Pico

Under Setup of the readme in the main repository it says "The pre-built .uf2 file assumes the data pin is on the Pico's GP18 pin."

Any help would be much appreciated, I tried compiling it using the Arduino IDE but couldn't get it to compile

Thanks for trying, I did reach out to DavidPagels but he said he does not do customer builds! It's just frustrating he decided to choose such a high pin rather than a lower one.

Had some success this morning, I can now build DavidPagels project. I thought I had changed it from the pico_w to a plain RP2040 and set the pin to 2 (from 18) however it appears I didn't save the change to the board type! If I attempt to build for a plain RP2040 it barfs and fails to compile.

You can download the picw_w / pin 2 uf2 file from https://www.avonrise.co.uk/retro_pico_switch/retro_pico_switch.uf2

Edited to correct my build boo-boo

Thanks so much, I'll give it a go now!

To answer your question regarding why I want to use a Seeed board rather than a Pico, is because it's smaller. The smaller the footprint the better

Only just got round to testing it, unfortunately it's not getting picked up by windows. I am trying it with a standard Pico and not a Pico W, would that make a difference?

Edit/ Just tried with a Pico W and I have the same issue, it's not showing in Windows.

I've just had a look using another adapter I've built, and I can't see anything obvious in Device Manager, when I unplug it and plug it in, nothing new appears. But when I look at 'Setup USB game controllers' it's listed in there. Using your build it's not listed.

Don't worry about it mate, I feel like I've wasted enough of your time, I really do appreciate you trying though
