Hi,
I have nt used I2C before and need someone to help! I have connected a second EEPROM to the one that I use to download a program to the microcontroller.
My question is quite naive. How do I address it and what part do the pins A0,A1,A2 play. What part does the unique address that is built in at time of manufacture and how does that assist me ?
The first EEPROM has all A0,A1,A2 pulled to ground. I think its addressed at 000
I have the second EEPROM connected to SCL and SDA and the pin A0 is pulled high because I think it must be hardwired unique on pins A0,A1,A2.
Am I correct ? What would the address of the second EEPROM be ?
Thanks.
