| 1 | + | ## About | |
| 2 | + | ||
| 3 | + | UnoLib is set of routines translated to Pascal from Arduino sources dedicated for Arduino Uno (ATMega328p). Although the library is distributed with AVRPascal, it can be used independently by for example FPC IDE or Lazarus with FPC built for use with AVR microcontrollers. | |
