PTS200 ESP32 based iron possible ironos port

[pykpkg47]

the PTS200 is a esp32s2 based iron sold by some chinese shops. it looks like the github user [Edddddddd](https://github.com/Eddddddddy) is behind this device. there exist a public repo with the source code of the firmeware(sadly license file missing so no true open source firmeware).

Is it possible to port ironos from stm32/riscv to esp32.

Hia,
Absolutely this could be supported.

It would require a fair amount of hacking to make the esp-idf framework want to work in the current build system but it could be done. ESP32 already supports FreeRTOS so there is no porting there to be done, would be a fairly simple port apart from figuring out a build system setup for it.

Only problem I can see is the dumb USB-PD controller wont let IronOS read out the current limit; so it would be possible to overload power adaptors.

At this point in time i dont have a huge amount of time to do a new port; but if there is sufficent interest I can look at picking one up.

I notice some vendors are selling a "PTS200 v2" but I can't find any information online about whether this is actually a different hardware revision to the soldering iron.
