Well readCSV. I had no idea about atof, strtok, etc. They don't appear in the Arduino ref. Thanks.I wonder if this can be easily adapted to use String, Serial.readString(),.parseFloat() etc.
This is a very old Thread. Have a look at Serial Input Basics
It is not a good idea to use the String (capital S) class on an Arduino as it can cause memory corruption in the small memory on an Arduino. This can happen after the program has been running perfectly for some time. Just use cstrings - char arrays terminated with '\0' (NULL).
If you have any more questions I suggest you start your own Thread (Topic).
