Ok, I am really trying to give [Platform.IO](http://Platform.IO) a chance as I respect the advice of people with much more experience than I but so far I hate it. Can anyone kelp point me in the right direction of what might be causing these errors when I attempt to build the latest WLED Master? I really am trying to like it.

I tried to upload after this and it did succeed in uploading the code albeit extremely slowly but then it just kept re-uploading and I had to terminate the process and Vstudio crashed. ---

What board you have? ---

Thanks for the reply! I have several, 8266, ESP32, and I’m trying to get ESP32-Pico to work reliably. I think the cause of the ussue is this statement in Platformio.ini default\_envs = d1\_mini, esp01, esp01\_1m\_ota, esp32dev I commented it out and now I can specify just one board at a time. Now I’m trying to understand how the board definitions work and see if I can get something stable for the ESP32-Pico. ---

You might have a problem with ESP32 pico. Board have one core and as I recall somebody already has tried to flash such a board with limited success. Better if you use ESP8266 MCU or similar. Just uncomment Platformio.ini line with your board. ---

I really want to get this M5Stack operational, 8266 isn’t packaged like this is. > **[ATOM Matrix ESP32 Development Kit](https://m5stack.com/products/atom-matrix-esp32-development-kit)** > > Description Description ATOM Matrix is the most compact development board in the M5Stack development kit series yet with a size of only 24 \* 24mm. It provides more GPIO pins and is very suitable for handy and miniature embedded device... Funy thing is, compiling with [Platform.IO](http://Platform.IO) it has been perfectly stable but the button does not work. Arduino the button works but wifi connectivity is an issue. ---

Anyone ever see a guide for setting up/using [Platform.IO](http://Platform.IO)? I’m interested in taking a peek. ---

And by the way, the issues I was having was with an 8266, not the Atom. The Atom is a separate topic. ---

I’d love to see one as well. Learning curve is a little steep. I can’t even figure out how to force specify a board from within the project. ---

for me [https://github.com/Aircoookie/WLED/blob/master/.travis.yml](https://github.com/Aircoookie/WLED/blob/master/.travis.yml) was a good starting point. ---

Thanks @pille for the info. I’m still not sold on PlatformIO. Im still having an issue where I get build errors about files missing but then after 1 or 2 fails, it builds properly. Twice I’ve has to restart PlatformIO to get it to successfully build. Any advice on making it wasy to switch back and forth on hardware platforms for the build? Just manually editing the platformio.ini for each build? ---

If you press platformio icon on the left side you will see list of the tasks. Choose one at the time and you don’t have edit \*.ini file 🙂 Be patient and soon you will realize that you can do a lot more with Platformio than with Arduino IDE. ---

Thank you, that is very helpful. Now if I can figure out the inconsistencies in the build success/failure I’ll be set. ---

I found out if there are any GLOBAL libraries configured, they override any project library version requirements. I removed all the global libraries and suddenly could succeed 100% with compiling using PIO and WLED. ---

Thanks all. Ok, so I think I’m comfortable with PlatformIO and building for multiple boards and getting used to it. How do you all keep current with the changes to WLED-Master? Can you point PaltformIO to the Git repo and automatically update or do you just manually maintain a local project folder? Also, for a shared folder/computer scenario, what do you keep shared and what do you keep on the local computer? ---

If it helps anyone, I now have 3 computers sharing a common Onedrive shared file structure by setting the following 2 Env variables on the systems to point to local dirs. `PLATFORMIO_CACHE_DIR` Allows one to override [“platformio.ini” (Project Configuration File)](https://docs.platformio.org/en/latest/projectconf/index.html#projectconf) option [cache\_dir](https://docs.platformio.org/en/latest/projectconf/section_platformio.html#projectconf-pio-cache-dir). `PLATFORMIO_BUILD_CACHE_DIR` Allows one to override [“platformio.ini” (Project Configuration File)](https://docs.platformio.org/en/latest/projectconf/index.html#projectconf) option [build\_cache\_dir](https://docs.platformio.org/en/latest/projectconf/section_platformio.html#projectconf-pio-build-cache-dir).
