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) #### Related - https://github.com/RobTillaart/PrintCharArray captures data in a char array buffer. - https://github.com/RobTillaart/PrintSize counts length of a number of print commands. - https://github.com/RobTillaart/PrintString captures data in a String. ## Interface ```cpp #include "PrintString.h" ``` - **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 #### Must - documentation #### Should - keep in sync with PrintCharArray class - testing - examples - add new ones - rename examples - add functions like **repeat(char c)** to inject e.g. 7 spaces etc. - add error flag #### Could - PRINTSTRING_LIB_VERSION #### Wont ## Support If you appreciate my libraries, you can support the development and maintenance.
