# PrintString
|
|
|
|
Arduino library to print to a String.
|
|
|
|
|
|
## Description
|
|
|
|
PrintString is a class that buffers a number of print statements in a String.
|
|
This String can be requested to process later.
|
|
|
|
- buffer slowly generated data, and send it with minimum time between bytes
|
|
e.g. to maximize packets for Ethernet.
|
|
- print to buffer to see how many chars the output is;
|
|
use to prevent "display line overflow"
|
|
(e.g. floats)
|
|
|
|
There is a relation to https://github.com/RobTillaart/PrintCharArray and https://github.com/RobTillaart/PrintSize.

|
## Interface
|
|
|
|
- **PrintString()** constructor.
|
|
- **size_t write(uint8_t c)** workhorse I of Print interface.
|
|
- **size_t write(uint8_t \* str, uint8_t length)** workhorse II of Print interface.
|
|
- **void clear()** wipes the internal String buffer
|
|
- **int size()** current usage of the buffer.
|
|
- **String getString()** to access the buffer.
|
|
|
|
|
|
## Operational
|
|
|
|
See examples.
|
|
|
|
|
|
## Future
|
|
|
|
- testing
|
|
- examples
|
|
- add new ones
|
|
- rename examples
|
|
- add functions like **repeat(char c)** to inject e.g. 7 spaces etc.
|
|
- add error flag
