Facts:
- esp-idf v4.0
- macOS 10.5.4
Problem:
I want to get time based interrupts (timer / alarms). So I studied this example: https://github.com/espressif/esp-idf/tr ... imer_group
I can compile it and flash it a ESP32-WROVER-V DevKitC board. As soon as I copy the content of the above mentioned example to my own project code, I cannot compile it anymore using
