Just installed build 2023 (latest) to try testing with it. I was looking for MrlComm.ino and friends to upload to the Arduino, but that used to be present in the resource/Arduino/MrlComm directory but there is no resources directory in teh 2023 installation either on Linux or Win10. And a search of the directory tree for 2023 doesn't yield anything.
Was this an accidental omission? I'm using the version from build 1.0.2020 which was the newest I had before downloading 2023 and at least for the servo service that one appears to be working.
I also was finally able to get things installed on a Win10 64 bit box for testing, so we will see how it works there.
