Re: [EE] Saving "printf" arguments for later? Real-time on slow processor.

I had been following this thread with some interest. Some time ago I ran 
into something quite peculiar involving printf. In recent years I have 
used, almost exclusively, ESP devices, mostly ESP32. My code is full of 
Serial.print Serial.println statements so I can follow the program flow 
in trial runs. I would occasionally get a device that compiled well 
apparently with plenty of resources to spare but the device would get 
into a continual reboot loop at runtime. Somewhere I read that this was 
caused by the Serial.print statements and replacing them with one printf 
statement would fix the problem. To me this seemed counter-intuitive. I 
expected printf to have much more overhead. But it works! I now use 
printf whenever there is more than one variable to display and sometimes 
even for only one. I have no idea why this is. Does anyone know? Thanks.

My IDE is Arduino with which I have had an ongoing love / hate 
relationship. I keep saying I need to get something better but I really 
don't want to endure another learning curve.

Thanks again,
