I got my t-beam 1.1 yesterday and flashed both today using platform.io following the short write-up. I could add a few things like “wait for a few minutes for the build” which seems like a long time considering I’m using a beefy Mac. I guess I’m used to interpreted languages these days - instant gratification!
I have to say the platform.io integration to Visual Studio is really slick and being able to upload and monitor the logs (even though I don’t know anything about arduino) is very nice!
