Nov programski jezik sa nazivom "HACK" Smile

http://hacklang.org

Zasniva se na PHP ali je nadogradjen sa striktnim tipovima promenljivih kao sto to ima u C, C++, Java ...

omogucava da svaki atmel AVR cip postane USB kompatibilan

cak i oni od 100din i manje...

:frantics:  Big Grin

Nisam bas ljubitelj SW USB implementacije, ima dosta mana ...

Ali zato mnoooogo gotivim ovaj vrlo vrlo zanimjiv PIC16F1455! To je redak mikrokontroler koji ima HW USB implementaciju a nije mu potreban kristal za rad!

Probao, radi odlicno! Sa njim moze da se napravi odlican minimalisticki interface USB<>RS232 ili USB<>I2C ili vec nesto trece sa dosta brzom USB komunikacijom.

Dakle nije to isto kao sto ima Cypress ili oni cuveni FT-ovi koji rade bit-bang, taj PIC ima neku specificnu foru za sinhronizaciju USB clock-a ...

I cenam mu je nesto smesna, ja sam ih ovde nabavljao cinimi se za oko 150din ...

Sve su to kontroleri sa SW USB implementacijom koja radi bit-bang (inace to radi i ona LIB sto si pokazao) i to je cca 10-15x sporije nego onaj spomenuti PIC Smile

Nekima (meni npr) je jako bitno sto nemam kristal a imam bas finu brzinu komunikacije, nije mi sporan kristal zbog cene ili prostora na PCB nego sto mi pravi harmonike (uzasne smetnje) u radio prijeminku koji je cca 5 milimetra od kontrolera Smile

Zvizde ti oscilatori samo tako po celom radio spektru …

<p><strong>USB connectivity</strong><span style="color:rgb(68,68,68);font-family:Verdana, Geneva, sans-serif;font-size:11px;">&nbsp;— Delivers full-speed operation without the need for external crystals... na ovo si mislio?</span></p>
<p>svi su napravljeni kao USB cipovi tako da nema potrebe za softwerskim budzevinama...</p>
<p>&nbsp;</p>
<p>inace pola njihovih cipova moze da radi sa unutrasnjim oscilatorima, i pola su USB, otud neki zadovoljavaju oba kriterijuma</p>

Nisam proveravao (ne trosim AVR) ali vecina bar PIC-eva koja ima USB a ima i interni oscilator NE MOZE da radi USB! To je frka … probao ja na nekoliko modela i nece, samo ovaj spomenuti PiC16F1455 mi je radio!

Problem je zbog stabilnosti oscilatora (i jitter), USB je vrlo zahtevan po tom pitanju a kod ovog PIC su to resili sa specificnom sinhronizacijom sa hostom.

Video sam neke jos novije kontrolere koji su slicno poceli da praktikuju za taj USB clock, uglavnom neki veci 16/32bitni.

<p>ljudi izvinjavam se sto vas prekidam, jel ima neko da se razume u tv prijemnike i signale? o cemu se radi? e ovako imam u sobi tv ei nis b40 sasija model 5140color bez txt on ima scart ulaz ali ga nikada nisam testirao, ne znam uopste ni kako da ga pokrenem verovatno na 0 jer jedino tu nema smetnji, znaci jedno pitanje je da li moze on da koristi taj skart a drugo da li bo mogao da gledam recimo hrvatske kanale ako bi stavio dvb t-2 prijemnik preko skarta i standardnu antenu sa pojacalom nalazim se prilicno blizu hr granice?

Nisam tv mehanicar ali imam scart na tv i spojen je na dvd . Scart sluzi za prenos slike i tona a trebao bi da radi na AV tipki ako imas na daljinskom , i ako imas reciver za prijem tv signala trebalo bi pratis hr signal.
