1) ok
2) avcc tai prie vcc. Vref pagal konfiguracija (programinimui dzin). Kondikas ten i gnd rekomenduojamas.
3) neponial ka klausi. Siaip generatorius turi buti pas programuojama auka (jei per ISP).
4) reseta reikia pakelti per ~10k i pliusa. Nes atjungus programatoriu, priklausomai nuo situacijos, resetas aktyvuosis ir mega neveiks.
5) pofig. Jei mato programatoriu. Tik ar to reikia USB programatoriui?

Pagrindines problemos buna su programinimu, kad yra net kelis generatoriaus variantai pas MCU. Fabrikinis- vidinis RC, taciau zaidziant fusais galima prisiprograminti iki isornio CLK, isorinio RC, isorinio greito ar leto kvarco ir panasiai. Ir jei nebus suorganizuotas atitinkamas clock, tai nelabai ir programuosis.
