Microcontroller › 8051 › Interfacing AT24c64 with 89c52 problem while reading & writing
Hai…..
while reading the eeprom it shows some garbage values.can anyone please tell me why is it so?
Hi Jenifer,
So many things could go wrong, like in your hardware make sure that you have connected the SDA and SCK lines to VCC through a resistor. Check you have connected the address pins A0, A1 of the EEPROM.
In your code make sure that you are using the same address to access the EEPROM.
Dear sir,
I am using AT24c64 and AT89c52. the resistor value am using is 22k. Is that enough or i have to make some alterations in resistor value? if it so means please tell me the resistor value……
Thanks in advance….
