Thank you for the examples! I now have a lot to study.
1) I got the external_rtc to compile successfully! The code was fine but in my windows environment in VSC I had to enable to set the kits to load as the included libraries were not being recognized. (see below)
[variant] Loaded new set of variants
[kit] Successfully loaded 1 kits from C:\Users\Steve\AppData\Local\CMakeTools\cmake-tools-kits.json
2) Also had to make make sure the project in the CMakeList.text was set to project(external_rtc).
3) I’m so new to this environment so I have a few questions: What is a good source to learn more about the VCS debugger? Where do the LOG_INF logs display? I put some printk statements in the code. Where do they display?
