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
