The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino ...

The Arduino Compile Phase So we’ve got C/C++ code. Compiling it into an Arduino project is surprisingly straightforward, and it’s well-documented in the Arduino docs wiki.

I have been delving (groping blindfold, more accurately) into the Arduino compiler adaptation code to try to determine how it handles the switch-over between its pwm activities, its set-I/O-to-output ...

However, the Arduino compiler tends to convert smaller switch/case structures into if/then assembler. With Arduino C, small if/then state-machines generally come out smaller a switch/case version.

I'm trying to compile example #13 for ESP32 Dev Module, without changing anything. Below are the compiled messages and errors. Would anyone be able to help? `In file included from ...
