Good morning!
I want to install on an RP2350 2W (labeled as “PICO2W”) the version of BASIC that comes “by default” with the PicoCalc (on an RP2040).
Which is the correct UF2 file?
I’ve tried some that I found by googling, but in every case the screen stays black and the device doesn’t work (the LED remains green, but there’s no image).
I assume I’m not using the right UF2.
Can you help me?
Thanks in advance.
These are PicoCalc specific releases maintained by @adcockm
[WebMite_PICO2W_V6.00.03_PicoCalc.uf2]
Dont works for me… : (
Ups!
The PicoMite_PICO2_V6.00.03_PicoCalc.uf2 woks on my Pico2W.
Thanks!
WebMite works here after a nuke.uf2 and it’s required if you want wifi without dns yet…
Also try the command : option cpuspeed 252000
And feel the power (and the heat) of a 252Mhz pocket computer 
With that speed, is a heat sink recommended/needed?
No, it’ll stay cool regardless. This isn’t a performance-at-all-costs application processor, and the clock speeds will always be too low for significant power dissipation.
I’m running at 378Mz, Pico2 with ceramic heatsink (can’t short anything if detaches). When really busy it can reach high 40’s C, without the heatsink it was approaching 60C (causing corruption, especially at even higher clocks). I’m working on a better heatsink (below) and will post the result when completed….
Higher clocks are not possible on the W versions due to a slow chip under the WiFi heatsink, rumour has it there’s another controller in there.
Wow, is that a heatsink of your design?
I’ll be waiting for that post.
Yes. My original milling setup wasn’t stable enough, wrecked the original when the crazy Mrs interrupted me with a drink and the bit snagged ripping through the first heatsink. This is the 2nd heatsink. I’ll be having another go at finishing ASAP now I have a much stronger and more stable setup. Mrs told off and well out of the way…. Others have managed stable 861Mhz with crazy cooling 
.
whether PicoMite_PICO2_V6.00.03_PicoCalc.uf2 will be turned up to the processor to cpuspeed 252000. Is it possible to turn on WIFI? Or somehow install packages? WebMite does not work, it resets all the time.
I had a 2W running at 252, the limit of its wifi module. They’re not all the same though so maybe yours is not capable. Try lower speeds, slowly increasing till there’s an issue. Don’t forget to backup all your programs !
Webmite works for me but I had to nuke.uf2 before, also I was playing with uf2loader before…
