Frekvencmetar -pomoc-

[Dragan83]

Ja imam ovaj fajl pisan u C programu i sad polako skapiravam sta je sta sad pokusavam da uparim izlaze sa pica na ulaze na lcd posto nisu isti na ovom mom instrumentu sa kesat net i sa ovog sto je ovaj c fajl , nisam prekopirao ceo fajl da nezauzima veliki prostor za pisanje samo pocetne detalje..
