(Solved) : Already Made Source Sound Scale Cdefgabc Rae Mi Fa Sol Ra Si Working Usually Use Codevisio Q29788387 . . . .

Ialready made a source but the sound scale (cdefgabc do rae mi fasol ra si do ) is not workingI usually use codevision and proteus (simulationprogram)Avr atmega 128Here is my program source help..PORTG is piezzo buser speaker
