Run on a esp8266?

[vaaski]

First off a big thanks to Dave and everyone else who worked on this project, this is exactly what I've been looking for!

I immediately wanted to try it out, but I only have a nodemcu/esp8266 laying around. From what I can tell, the 8266 is similar to the esp32, with lower performance. I've tried adding a dev_ as well as an env: section for it in the platformio.ini, but my knowledge in this area is pretty limited as of now and I am pretty much just guessing things.

The build unfortunately failed, log below.

Has anyone tried to make this work on a esp8266 or should I just be patient and order some esp32?

p.s. It builds fine with the default config, but takes a weirdly long time on my M2 MacBook Air, running time pio run takes exactly 10 minutes, with my CPU in the high 90°C range the whole time. I feel like it should be faster considering it takes the M1 MAX only 20 seconds

edit: On my Windows i7-9700K machine it took a whopping 27 minutes, is this normal?

I have not tried to make this work on an esp8266; my device is a M5StickC Plus. However, it seems ESPmDNS.h is part of the espressif32 platform, as this is where it is located on my system: ~/.platformio/packages/framework-arduinoespressif32/libraries/ESPmDNS/src/ESPmDNS.h. My guess would be it is just not included in espressif8266.

The thing you're running into on your M2 vs. your M1 I can't comment on, because I have neither machine/CPU. What I do know is that the default setup - that being the one you get when you clone this repo and do not set default_envs in platformio.ini - builds all projects. That can indeed take a fair amount of time. This is because each project has its own build configuration (like its own set of build_flags), which means each project and all of its source code dependencies needs to be built from the ground up. Because of this, the GitHub CI runtime on this repository is now about an hour.

Then I just won't bother and pick up a esp32 somewhere, thank you.

Regarding the build times that makes a lot of sense as I had the feeling that I saw a lot of duplicate dependencies scroll by while building, running pio run -e demo took 23 seconds on a fresh clone.

[rbergen]

Yes, 23 seconds for a build of demo only sounds about right to me. :)

Not much hope on that one, we already used multiple cores and other ESP32 features. You’re welcome to try to make it work if that’s possible by putting everything on the same FreeRTOS core, etc, but I’ve never tried it! I’d suggest you get some ESP32s, they very cheap now! If you can afford it, the M5StickC Plus is likely the best one, about $20, and it has a screen and mic and lots of hardware inside… - Dave
