6/10/2023 0 Comments Fast serial print arduino![]() Any string does this, of course, but prints can eat up string space quickly, especially if you add a lot of debugging code.Īnother problem when I mentioned the code to others seemed to be the waste of space for the buffer character array. for one thing, the memory they used for the format string is in RAM, which means it contributes to ‘eating up’ the 2k memory that the ATMega328 on the Arduino has to use. ![]() However, while I found they did the job, they weren’t quite what I wanted. In a previous article I described how to add the old-fashioned print() function to Arduino to improve debugging – after all, it gets tedious to use a separate Serial.print() function for each type – and inserting information into a string is printf’s specialty.
