lệnh ghi eeprom nội của pic ntn?

[Mr.Bi]

đây là 1 cái code ng bạn mới đưa cho tui !

void write_ext_eeprom(unsigned char address, unsigned char data)
{
start();
write(0xa0);
write(address);
write(data);
stop();
DelayMs(11);
}

/****************************** ****************************** ******************************/

unsigned char read_ext_eeprom(unsigned char address)
{
unsigned char data;

start();
write(0xa0);
write(address);
repStart();
write(0xa1);
data=read(0);
stop();
return(data);
}

while(i<=10) /* Viet 10 so vao eeprom */ //dung yeu cau roi nhe
{ 
PORTB=i; // xuat ra cho nao do. de de nhan biet moi lan vietnao eprom cho xuat ra led
