(I know I am supposed to post source, but my project is too large, and this is an IDE issue I believe.)
Ok, bonehead move this evening. I went to open my project and selected the wrong IDE. I have been using 1.8.16 but it opened in 2.2.1. And the 2.2,1 IDE decided to start updating things. I tried to build the project anyway, but there were a very large number of C++ warnings I never saw before (not a warning setting, I checked that.) But it uploaded to the board. But it does not work well. (The project is too large to post here, but it is driving LEDS using FastLED, and now they flicker light crazy.)
So I closed the 2.2.1 IDE, used Dropbox to rewind the libraries folder and project folder to yesterday before tonights changes (hopefully undoing any library changes), and relaunched the project in 1.8.16. But now, that IDE shows all the same compiler warnings (C++ issues) that never showed up before. Also, the output of the 1.8.16 IDE when compiling looks very different than it used to, looking just like the output of the 2.2.1 IDE. For example, the end of the compile used to display a bunch of white text with stats about the build (ram and program space use, etc.). Now there is a bunch of red text with very different info. It's like the complier from 2.2.1 is now running on 1.8.16.
The same target board is elected as before.
Any idea what else might have been updated that is not in Libraries or project folder? I am trying to get back to the build that work perfectly (the source code has not changed) but the compiler changes are preventing that from happening.
Any ideas what I have not backed out? Maybe the board files? (Where are those kept?)
I can post warning messages or anything else that might identify what changed.
Thanks
