How do I split text in Arduino?

How do I split text in Arduino?

In an embedded environment like Arduino (even for a Mega that has more SRAM), I’d rather use standard C functions:

1. strchr() : search for a character in a C string (i.e. char * )
2. strtok() : splits a C string into substrings, based on a separator character.
3. atoi() : converts a C string to an int.

How do I split a string into a substring in Arduino?

You can use this function as follows (with “;” as separator): String part01 = getValue(application_command,’;’,0); String part02 = getValue(application_command,’;’,1); String part03 = getValue(application_command,’;’,2); EDIT: correct single quotes and add semicolons in the example.

How do I find the first character of a String in Arduino?

The String object indexOf() method gives you the ability to search for the first instance of a particular character value in a String. You can also look for the first instance of the character after a given offset. The lastIndexOf() method lets you do the same things from the end of a String.
