I picked up the book ‘Developing IoT Projects with ESP32’ and am working through things. After struggling to get anything to work with PlatformIO on my Windows machine I switched over to my Mac and got past a good number of hurdles getting as far as working on the first FreeRTOS example. With my project directory found in github.
Things seem to start off but end up in a panic loop and new to this platform I am not sure if I missed some configuration step, if the books instructions are dated, or if I should just write the example off as being busted and move along to the rest of the book. If anyone could give direction it would be appreciated. There is a Discord channel for the book but it appears to be unmaintained and defunct…so asking here.
