Salut!Imi puteti spune daca este posibil sa redau sunete folosind un microcontroler precum PIC16F877A sau PIC18F4620 si un convertor digital- analog? Daca da, recomandati-mi niste DAC-uri pt asa ceva.Multumesc

nu ai neaparata nevoie de dac. vezi la http://www.romanblack.com/picsound.htm este cum se pot reda sunete folosind una sau mai multe iesiri digitale.

ceva mai simplu gasesti la http://www.mikroe.com/ro/product/books/ ... lavlje.htm

de asemenea, la http://www.beyondlogic.org/pic/ringtones.htm mai gasesti ceva informatii.

toate asta ar cam fi destule pentru a face un pic sa cante. ramane sa mai si danseze...

bafta!

pai uite, DAC gasesti la microchip, de exemplu MCP4921 nu e tocmai scump. Acum depinde ce intelegi prin sunet. Poti folosi metodele de mai sus pentru anumite aplicatii limitate. Alternativ, DAC-ul poti sa il faci si din rezistente, iti trebuie R si 2R, eu am facut cu 10K si 20K, dac pe 8 biti pentru redat un wave. Calitatea nu e exceptionala, cel putin la 8 biti ai un zgomot destul de mare, dar poti mari rezolutia.
