以下是一个8051 读/写EEPROM的简单小程序，希望大家能够喜欢。

char buffer[32], ii; // Data buffer, loop variable
void main(){
P0 = 0;
P1 = 0;
P2 = 0;
for(ii = 31; buffer[ii] = ii; ii--) // Fill data buffer
;
EEPROM_Write(2, 0xAA); // Write some data at address 2
EEPROM_Write(0x732,0x55); // Write some data at address 0x732
EEPROM_Write_Block(0x100, buffer); // Write 32 bytes block at address 0x100
Delay_ms(1000); // Blink P0 and P1 diodes
P0 = 0xFF; // to indicate reading start
P1 = 0xFF;
Delay_ms(1000);
P0 = 0x00;
P1 = 0x00;
Delay_ms(1000);
P0 = EEPROM_Read(2); // Read data from address 2 and display it on PORT0
P1 = EEPROM_Read(0x732); // Read data from address 0x732 and display it on PORT1
Delay_ms(1000);
for(ii = 0; ii < 32; ii++) { // Read 32 bytes block from address 0x100
P2 = EEPROM_Read(0x100+ii); // and display data on PORT2
Delay_ms(250);
}
}
