arduino library for universal "char*"-compatible string: transparent access to ram(rw), flash(ro), eeprom(rw)
this library indroduces two types: ustr ucstr
- ustr is made to behave like "char*"
- ucstr is made to behave like "const char*"
they both can point to ram, flash(PROGMEM,PSTR) or eeprom.
of course this is slow, but sometimes simple code is better.
