@huggy-d1 Thanks. Let me know if anything is not correct…
Let’s say you accept all the default settings when installing VS Code & Platform IO’s IDE.
Go to Open Folder, then navigate to the wled folder you want and select it. It will then load everything. Click on Terminal, New Build Task. You can then select your board and the bin will be built. The bin will be in the same folder \ .pio\build, then by device and called firmware.bin.
Everything is correct. You can attach your board and upload your bin file without even looking to pio folder. On left side of your interface you have few buttons one of the button open for you bunch of the tasks you can perform with a project.
Next question: How do we set/partition flash in platformio? In the Arduino IDE there are choices for splitting flash into “regular” and file-system space.
