Question regarding custom components and threads on ESP32

[yawor]

Hi,

I'm new to esphomelib, Platformio and Arduino framework. Up until now I've been working directly with ESP-IDF.
I'd like to implement a custom component which would need to use threads. Is this possible in in esphomelib? I've found some examples of using pthreads with Arduino framework, but it was implemented on top of ESP-IDF and FreeRTOS. If I'm not mistaken, esphomelib doesn't use ESP-IDF at all.

The ESP32 arduino framework uses the esp-idf framework. So you do have access to all esp-idf stuff (esphomelib internally also uses a lot of esp-idf components rmt, ble, pulse_counter, ...)

Ah that't great. I've been looking for downloaded esp-idf but I couldn't find it so I've wrongly assumed that it uses some other implementation.
After your comment I've tried adding #include "freertos/FreeRTOS.h" into main.cpp (I should have done this in the first place) and it didn't complain during compilation.
BTW if I'm going to use SPI, should I use SPI abstraction from Arduino framework? Or can I use it directly from ESP-IDF? I don't intend to use another SPI device on that node.

I haven't tried either abstraction yet, but I think the esp-idf one works - except of course if you use the SPI controller that's responsible for the flash memory.
