Arduino Tiny

with newsoftwareserial, and the attiny85 at 8mhz, the uart could not work, if so...
in the NewSoftSerial.cpp file , search the line:
void NewSoftSerial::enable_timer0(bool enable)
and then change this

{

  if (enable)

#if defined(__AVR_ATmega8__)

    sbi(TIMSK, TOIE0);

#else

    sbi(TIMSK0, TOIE0);

#endif

  else

#if defined(__AVR_ATmega8__)

    cbi(TIMSK, TOIE0);

#else

    cbi(TIMSK0, TOIE0);

#endif

}

in this

{

  if (enable)

    sbi(TIMSK, TOIE0);

  else

    cbi(TIMSK, TOIE0);

}

and then it should work.
hope this help :slight_smile:
