You seem to have some weird workspace setup. You have 3 workspace open at once and you have .code-workspace files in your src – these are not generated by PlatformIO. Where do they come from? Any third-party extensions installed which might conflict here?
First you should right-click on every folder in your work space and remove them from the workspace. Then use the left-side PlatformIO Icon to open PIO Home and re-open the project you want to work on.
Thanks for the quick response. Obviously I still have much to learn about Platformio.
I only see the one workspace - Radio_Mailbox_Master Workspace. Each of the subheadings (folders?) under the this Workspace are cloned GITHUB repositories for arduino programs (radio_mailbox_red, radio_mailbox_green, radio_mailbox_Yun_yellow- i deleted the 4th respository).
I have been modifying each of these programs, compiling, uploading, testing, updating GITHUB successfully until now when I no longer see the blue toolbar that you have at the bottom of your screen, which allows me to compile & upload to arduino boards and sync Github.
I am not aware of any conflicts and haven’t loaded any new components to PIO that I’m aware of.
I did as you suggested and then opened an old project I found at PIO home ( I couldn’t find the projects I was working on at PIO home, but they are in a folder on my PC).
Here is what it looks like now. Still no blue toolbar at the bottom of the screen.
Am I supposed to have one workspace for each program/project?
