Intrebarea nu-i foarte clara. Tastatura e musai sa fie una tip PS2 (seriala) ?Nu-i mai simplu trei butoane (pe trei pini IO) R, S si D ?

da...trebuie comunicatia sa fie prin tastatura de la PC...la apasarea unor taste precum(P,D,S...)sa se genereze semnalele .Adica daca apas P sa se genereze un semnal panta daca apas S ,uC scoate semnal sinusoidal....si tot asa

Tu esti sigur ca PICul asta scoate semnal sinusoidal ?Ai putea sa documentezi cumva afirmatia.

Poti sa scoti semnal PWM modulat in forma sinusoidala, il filtrezi si ....

Picul nu scoate semnal dreptunghiular, da s-a dat un potentiometru electronic, si cu ala poti aproxima sinusoida...
