ai mai pus intrebarea asta si la PIC, crezi ca din cauza Microchip nu sti tu ce e aia pwm si intrebi la "alte microcontrolere" . Daca tot suntem la alte controlere faci asa : iei un "alt controler" citesit datashet ca sa sti sa generezi pwm, daca nu sti ce e pwm ai google, si generezi pwm cu controlerul respectiv, sau cu altu, semnal ce printro rezistenta il bagi in baza unui BD235 de exemplu; al carei emitor e la masa iar colectorul prin bobina ta la plusul de 12, sau 24 sau cu cat se alimenteaza bobina . Nu uita de dioda 1N4001 din paralel pe bobina cu minusu diodei la plusul de 12,24 etc .
