I usually use atmega128 codevision

I finally finished coding and exactly write the speaker code sound scale output if i press swtich

Please help me.

#include #include int AD_volt=0; int position=0,BJT[4]={0xFE,0xFD,0xFB,0xF7}; int number=0,segment[10]={0xC0,0xF9,0xA4,0xB0,0x99,0x92,0x82,0xF8,0x80,0x90}; int msec=0, sec=0, min=0;
