Dilema oko 16F628
#4
Svaki PIC ima vise opcija za svoj "master" oscilator, programski se bira da li koristi interni R/C, ekterni Quartz ili Clock Input iz nekog drugog izvora.
Kada se izabere tip oscillatora, interno ima PLL koji dize taj clock na recimo 20MHz ili neki drugi modeli na 40-60MHz i to se koristi za pokretanje "programa".
Fleksibilno je u smislu da se moze uzeti neki standardni kristal i da se njegova frekvencija tacno umnozi onoliko puta koliko je potrebno i to podesavanje se postavi u program/HEX.
Ako je izabrano npr 4MHz i vec imas gotov program (HEX) onda mora da se koristi taj kristal, a ako se poseduje source-code onda je moguce da se izmeni program i postave neke druge kombinacije vezane za oscilator.

Inace pohvale za taj SWR/POWER metar, vidis da to nije toliko strasno sa PIC-evima, samo da se napece ispravno, nabodes to na plocicu i vozi Misko Wink
