Buna seara!Pana acuma am programat in ASM , insa vreau sa incep sa invat si ceva C, folosesc MPLAB + High tech C si nu gasesc un "macro" ( librarie ) buna si nu as vrea sa o folosesc tot pe cea din ASM :) . Daca are cineva una care sa aiba si configuratia pinilor cat mai usor de customizat :) .Multumesc mult :)!P.S.: Daca exista vreun compiler C mai bun ca asta dar atentie , FREE , astept pareri , multumesc .Din cautarile facute asta parea cel mai bun...

O librarie pe care am scris-o in AVR32 studio ... se poate porta usor si pentru PIC doar modifici pinii unde sunt definiti .
