RPi PICO mPyEasy support

[Budman1758]

Just bought a couple of these new Raspberry PICO units. Will this software run on them? Haven't received them yet. Just curious.

I am curious too. Native micropython runs on it and API is something similar than ESP32. Basic functions may work on Pico but i do not see any network interfaces. Maybe W5500 can be coded to work on Pico but currently W5500 is only works with STM32 chips.
2MB flash is not too much but as i see OTA will never be supported, so it may be enough - as changing firmware needs physical button press and copying firmware onto them manually.

In theory W5500 will compile with RP2 but i am unable to make it yet. Maybe micropython official will be added soon.
micropython/micropython#6819

Micropython STM32 driver for W5500 LAN is not compatible with RP architecture.

But i've succesfully modified Adafruit_CircuitPython_Wiznet5k to work with micropython and run a subset of mpyeasy.. although there was an even larger problem, as _thread (multiprocessing) module is working very strangely, differs from any other ports such as ESP32, resulting in constant freezes. So i have to say that Pi Pico in its current state is absolutely not usable with mpyeasy. :(

Current status:

• adafruit wiznet5k circuitpython driver works with micropython, with static IP address. dhcp is untested, but may not work.
• microWebSrv requires working threading implementation, which is unstable at Pico port without GIL, unusable
• picoweb requires uasyncio, which works at Pico, but adafruit wiznet5k socket driver somehow works only blocking IO mode, so this is also unusable
• Adafruit WSGI minimized webserver finally looks like its working with wiznet5k socket, but may fail with larger html files, as the whole response has to be fit in the memory, testing in progress

Finally Wiznet driver works with micropython. Although threading is not really work on RP2 platform, so i had to partially rewrite the code to asyncio:

Releases can be reached here:

And this is for W5100S-EVB-Pico (W5500 is still not working on micropython)
