PrintSize
Arduino library to determine the length of print statements
Description
PrintSize is a minimal library to determine the length of a variable when printed. This includes printing of floats, integers in decimal or hex notation.
Works for print(), println() and if supported printf() e.g. ESP32.
Finally since 0.2.0 it has a total counter to add up the characters "printed" since the last reset() call. (see example)
Operational
Example shows the right alignment of 10 random numbers
Example shows (elementary) line fitting
Can be used to calculate the needed space.
- to properly do a right alignment e.g. for numbers or variable text
- do left alignement and overwrite previous output with just enough spaces.
- centering of numbers
- see if output will fit into a line / display
