juk viskas prasyta prie projekto:
kompiliuoti hex nereikia, ji tik su avrdude ar kokiu kitu softu irasyti i attiny |

the frequency of the interrupt overflow is determined by the
prescaler and overflow value.
freq = clock_frequency / ( 2 * prescaler * overflow_val)
where prescaler can be 1, 8, 64, 256, or 1024
clock_freq is 8MHz
and overflow_val is 16bit
the overflow value is placed in OCR1A, the prescale is set in TCCR1B
so for example:
A good POV frequency is around 400Hz
desired freq = 400Hz
clock freq = 8MHz
8MHz / (400Hz * 2) = 10000
since 10000 is less than 655536 (largest 16 bit number)
OCR1A = 10000 and the prescale is 1
*/
TCCR1B = (1 << WGM12) | TIMER1_PRESCALE_1;
OCR1A = (uint16_t)10000;
TIMSK |= 1 << OCIE1A; // Output Compare Interrupt Enable (timer 1, OCR1A)
sei(); // Set Enable Interrupts

tai susikelk AvrStudio ir po to WinAVR
is programatoriu valdymo softo gal koki PoniProg ar IC-Prog, kuris labiau tiks tavam varinatui arba mokykis su avrdude dulkintis  tiesa jam yra kazkokia amzinai neveikianti grafine aplinka. |

| asm yra tekstinis failas, o i mcu flashinasi binarinis (bin, hex, raw ir t.t.) |
