EEPROM read

Posted: Tue Jan 12, 2010 11:32 am

Code:

//FRONT SENSOR DETECTION ALGORITHM
set_adc_channel(0);
delay_us(20);
val1=read_adc();
delay_us(20);
read_eeprom(0x2100);
delay_ms(200);

if (val1<vref)
{
write_eeprom(0x2100,val1);
delay_ms(200);
}

F1=read_eeprom(0x2100);
delay_ms(50);

while (TXIF == 0);
TXREG = printf("%2x", F1);
TXREG = printf("\r\n");
delay_ms(10);

Hello guys, i am having some problem to read the data at EEPROM. I have send the "F1" value by using RS232 communication, but i'm get "0" as an output at the hyperterminal. Is there any problem with my read code. Hopefully u guys will help me.

Which PIC do you have?

Code:

write_eeprom(0x2100,val1);

0x2100 is an awfully large EEPROM address. You sure your EEPROM is that big?

Read this thread about using the correct address range for the eeprom
