How to use under Windows?

[Deous]

Couldn't find how to compile ulp asm file under Windows and then how to integrate with f.ex. esp-idf project. More documentation would be nice

The steps for Windows are same as for other OSes: download the toolchain, add it into PATH (https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/ulp.html#installing-the-toolchain). Support for ULP programs is present in ESP-IDF, please refer to system/ulp example. Build system integration is described in https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/ulp.html#compiling-ulp-code.
