Si5351 + PIC16F1455 USB controller
Da ovo je super, vec mogu u i da zamislim onaj sklop sto si radio sa Macolom da ima u sebi i precizan Cref preko kojeg znate koji je tacan otpor pt senzora i onda ovo sve po redu preko freq..
Ne mogu samo da napravim figuru u glavi kako bi se to moglo odraditi preko pwm compare-capture, nekako bi valjalo dovesti oba kristala na pribliznu vrednost pa kroz taj pwm kompare dobila razlika frekvencija na osnovu koje dalje odradila autokorekcija tamo nekog drugog preciznog pwm koji koji je prikljucen recimo na ovaj freq2napon, verovatno da moze da se ostvari komparacija neke dve frekvencije preko lmk da se dobije razlika u frekvenciji na osnovu koje dalje stelujemo neki fini pwm koji kontrolise ovaj freq2napon, i to tako zakljucano u loop i ovom rezolucijom 0-3.3V @ 0.1C bi izuvalo sve ove dacove i vrefove bez pogovora : )

Edit: mesam ja tu babe i zabe, pwm compare nema ovde sta da trazi jer tu je razlika jako mala izmedju dva kristala zato si stavio taj xor koji hvata tu finu razliku od 10Hz dok ne dodje do faznog poravnanja. Xor ustvari tu ima svrhu da posalje interupt mcu i da kaze da su dve frekvencije spojene fazno, to mi je jasno. Jasno mi je i upotreba lmk, sa njim bi se stelovala frekvencija dobijena s jednog od kristala do tacke gde xor dalje preuzima. E sad nije mi jasna ta treca stvar koja treba da kontrolise oven, odakle se dobija ta treca stvar, pwm ili sta vec, isto iz lmk samo sa drugog izlaza? To mi je malo nejasno ako bi sad tu frekvenciju prosledili na freq2napon, tu je rezolucija ravna nuli, jer za rezoluciju 0-3.3V treba nam promenjiva frekvencija od recimo 0 do 100k ili od 100k do 200k nebitno na freq2napon sklopu. Kako si zamislio ovu trecu stvar? Ja bi se usudio cak i da krenem sa crtam sheme da se to eventualno i prakticno proba, ali mi je nejasno i dalje. : )
