Maths help: log() - Programming - Arduino Forum
Oct 6, 2015 · On the Arduino the log () function is the natural log, not log base 10. So you need to use log10 (). Pete. The log () function expects a floating point number to be passed to it. You're passing an int. What happens with: a = log( (float) i); instead? You want log base 10. You need to divide by log (10) to convert to common log.

Mar 26, 2023 · You can set the log level from the Arduino IDE via Tools -> Core Debug Level. By default it is set to NONE. I just had to add my thanks to hcheung! Changing the #defines and using esp_log_level_set() made no apparent difference. Setting Core Level Debug made all the difference, seeming to override the #defines mentioned above. -- John B.
