Re: I2C Problem
Hi,
For example in a serial eeprom like 24LC128, there are 3 pins (A2,A1,A0) on the IC which allows the user to assign an adress from 2^3=8 different adresses to each device. According to the device adressing section of its datasheet, the adress of each device is in the form of 1010 A2 A1 A0. This means if you connect all three pins to GND, then the adress of that device will be 1010000. Similarly, it will be 1010111 if you connect all three pins to VCC.
If you have 3 serial eeproms like 24LCXXX in your circuit, you should wire these three pins differently in each device so that they all have a unique adress you can use to read/write.
I've given this as an example, the adressing scheme may vary for different device families.
Regards.
