First - thanks to all contributions here about the PicoCalc firmware and thanks for the neat device really arriving after some wait time!
I now fiddled around a bit and want to implement a simple tool showing me the wlan’s in range to see why my own wlan sometimes does not behave like expected.
After pluggin the pico pi 2 w into the device i only found one firmware that works for what i want to achieve - its the micropython_pico2w.uf2 from the original clockworkpi PicoCalc sd card - which can be found here as well PicoCalc/Bin/MicroPython/micropython_pico2w.uf2 at master · clockworkpi/PicoCalc · GitHub
To make a wlan scan i found to use the network.WLAN(network.STA_IF).scan() - don’t forget to activate network.WLAN(network.STA_IF).active(True).
To display some graphics i used the module picocalc.display drawing functions .fill(color), .rect(x,y,w,h,color) - but found only 16 colors possible, even the build in lcd can show more colors.
For my simple tool its enough, but could be nicer.
Nice finding was the battery level - can be read with picocalc.keyboard.battery() - bit 8 is charging indicator lower bits are level in percent - nice.
zenodate firmware got a boot loop on my device - no idea what’s wrong (with or without filesystem, for then pico 2 w)
picomite for pico 2 w has no wifi support yet - nice basic interpreter - can show more colors
Anybody a hint how to get more than 16 color or which firmware give a try?
